/diy/ - Do It Yourself

Hi diy,

Got some reclaimed wood.

Can someone tell me what kind of wood it is?

>>1588976

>>1588901
>hydrofluoric acid
Where the fuck did you get this stuff?

>>1588976
My impression is cedar of some kind. The grain, color, and that it was chosen for a fence post tell me this...

>>1589039
Thanks!
It was used as construction wood. I salvaged it from a demolition site, hoping it would be oak.
Now after seeing it in daylight I'm leaning more towards soft wood

>>1588901
No. If you want cheap refrigerant use propane.

>>1589066
I can't use propane, since shit will explode.
Also, r134a will be banned soon too.

Bit time sensitive, I need a storage solution for little shit, likely getting it off amazon, does anyone know any deals on alot of storage for the 25$+-5 range?

I know next to nothing and these people go out of their way to not give you a sense of scale for their products. I need something to store miscellaneous dremel, solder, and tools and these seem like the best way.

open to all suggestions

>>1589069
To explode it you need sparks and air.

There are no sparks and air inside of coolant lines, it will not explode unless you have leaks that are confined in a space and the concentration of propane is high.

Hydroflouric acid as OP mentioned is 1000 times more dangerous than propane.

>>1589069
Dust Off air dusters
4pk for $16 (4 - 10oz cans)
1,1 difluoroethane (R152A)

>>1589089
Hm... Where can I get big tank of this goodness? I know a person with EPA, who had donated me a tank of R-410A for leaky (once in 3 years I need to refill it) AC I have. I think he can do it too.
>>1589074
My car AC has leaks, and has sparks, so propane is not an option. And I think isobutane would be more appropriate for this. It is much closer to R12

>>1589113
Oh wait, R152A is flammable...
You know what? Fuck AC. I will use R2WD (roll two windows down) refrigerant.

>>1589117
Or wait... Can I convert system to butane or propane, keep flammable stuff outside, and use coolant to transfer heat between heater core and some sort of heat exchanger?

>>1589138
Hm... This seems like real legit idea.
Will it work?

>>1589072
Just go to Walmart and find something you lazy nigher.

I wouldn’t do an actual tackle box for misc parts. You can get the Plano style flat boxes for a couple bucks and they come in all different configurations. 3700 style is the larger one, 3600 is medium, 3500 and smaller are little ones.

I like pic related. I think it was $11 for a 2-pack from Wally World and you can stack them and they lock together. They’re deeper than typical Plano boxes and you can take lots of dividers out if you want a large storage area.

Otherwise Dollar Tree has tons of little tupperware crap.

>>1589113
>has sparks, so propane is not an option
>>1589113
>isobutane would be more appropriate
isobutane is flamable
The correct replacement using isobutane is a blend of ~20% isobutane and ~80% propane by weight

>>1589199
Problem I have is simple, live to far away from well stocked walmarts, while they do have the bigger ones there, i'm not paying 80$ for plastic boxes.

apparently the box you mentioned is 100% out of stock everywhere, however I do like that format of expandability. happen to know any other brands that do this?

>>1589208
>isobutane is flamable
I know. This is why I want to have a heat exchanger, somewhere under hood, and use evaporator as radiator.
>The correct replacement using isobutane is a blend of ~20% isobutane and ~80% propane by weight
I will keep that in mind.
AFAIK charge should be 40% of R12, right?

>>1589235
So I don't even need high grade R290 and R600a, and I can use stove shit with smelly chemical?
This is actually brilliant.

I smoked crack once with a blind homeless guy. He had a food addicted seeing eye dog.
He was cool, but I could see what was going on.

>>1589028
I just know a man, who works in uni lab, who can get whatever I need.
Have you ever wondered what niggers in order to etch glass on buses and shit? They use HF since it is cheaper than special HF-free cream

>>1589113

can you not just go buy a redtek kit from your local autoparts store and be done with it

>>1589069
>Also, r134a will be banned soon too.
R134A isn't banned from manufacture or import, it's banned from being used in new products. (autos, refrigerators, etc.)
The replacement gas is 1234YF and it's $70 per pound.
R134A should be available for many years.

>>1589384
Hmm. That is isobutane/propane mix.
Considering that I have leak somewhere, I better put normal gas with smelly chemical, so I won't explode

isn't there some sort of US building code which states that any sort of electrical fixtures need to be stationary, unless it's designed to be on a swivel or something similar?

Can I use activated carbon labelled "for aquariums" to replace the ones on a kitchen hood filter?

>>1589117
Who gives a fuck if it's flammable? The chance of it igniting is smaller than your chances of crashing your car.

A leak big enough to start a fire will leak out so fast that it won't matter.

Is there any reason not to use metal drill bits when drilling wood?

Is there a reason not to use impact sockets (or whatever those black strong ones are called) for regular handtools?

>>1589519

I've never seen a twist drill bit labeled "for wood", so I use the same ones for metal and wood.

I also use impact sockets with hand tools when I don't have an ordinary socket handy. Same with extensions, adapters, u-joints, whatever.

Sounds great. Got a bunch of used drill bits from a mechanic, can't properly drill metal anymore without sharpening, figured I could use them around the house.

So as long as the sizes are available, is there any reason to keep regular sockets around?

>>1589544
Sharpen them, even shitty sharpenning will work for wood.

>>1589519
Bits for metal tend to break out and leave splinters on the exit side of the hole. You can drill halfway from each side to stop this, if it even matters, or you could clamp a piece of waste wood where your bit will exit. In deeper holes, especially in harder woods, a metal bit (with no "spur") will tend to follow the grain worse than a dedicated wood bit. Again, halfway from each side will help. All that said, I use metal bits all the time for wood, you just have to know your tools.

>>1589514
>Who gives a fuck if it's flammable?
I do, since I suspect that I have a leak inside the dash, and I'm too lazy to remove it.
>The chance of it igniting is smaller than your chances of crashing your car.
There were cases, where new R600a fridges exploded just because someone had opened the door and light switch made a spark. Also they don't braze them anymore, but use shitty compression fittings.
Fridges have just 70-100 g of R600a, while in car AC you will have 200-300g of R12a.

>>1589505
It’s all the same shit.

>>1589523
I snapped a 1/2” impact extension the other day using it on the breaker bar. It was a wobble extension so a little thinner, but I imagine a regular chrome one (even from HF) may have held up better.

Main downide to using the sockets on hand tools is probably the thick wall.

>>1589519

>Is there any reason not to use metal drill bits when drilling wood?

sometimes they grab too much and start going fucking insane cork screwing into the wood and sometimes its nice to have a nice hole. those spade bits are bretty gud for to make of the holes into woods

>Is there a reason not to use impact sockets (or whatever those black strong ones are called) for regular handtools?

lots of times because impact has a thicker wall they dont fit. recessed lug nuts come to mind if you need an example. other than that whatever keeps your watercraft bouyant

>>1589069
Shut the fuck up
Just use r134a it's not going anywhere anytime soon
You can buy cans from Walmart at a decent price
R134a is not flammable and isn't harmful to you in anyway, just don't try to get high off of it you bitchy queen

>>1589934
I don't want changing oil and shit.

>>1589427

see that third can labeled "leak stop"

regardless, how many cases of AC blowing up cars do you hear?

>>1589938
Well it comes with the territory, man
What exactly is your current plan? Do you even have one?
You will have to change the oil anyway when putting a different refrigerant in anyway

>>1589519
The difference between an impact socket and a crome one is that the impact socket is a little more springy to withstand impact over and over. Chrome will be a little more brittle actually, but that allows for them to have a thinner wall (at least this is what I learned from another mechanic)

So, what I've always been told is impacts can be used by hand tools, chrome should not be used by impact because they'll crack. I've broken both rules, and crome sockets definitely break where impacts don't. But that's why you buy lifetime gaurenteed tools anyway

>>1589942
Not much, since most refrigerants are non flammable.
LPG conversions explode frequently though. But

I think that stop leak won't help.
>>1589956
I have three options
>Real man doesn't need AC
>Find old new stock of r12 on eBay
>Fix the leak and fill hydrocarbon mix.
R12a Is compatible with mineral oil they used on r12.

>>1589996
But it has much more gas*

>>1590000
Czech’d

>tfw fan won’t run
>seemed like there was lots of resistance on shaft at first, fucked around with it, think maybe I cleared some shit out of the bearing
>now trying to figure out if something else burnt up while it was jammed
Mains/AC power confuses me. DC power does too, but AC is way over my head. Any clue what these 4 wires going to the fan should read? I turned it on high and was seeing if I could get 115V across two of them, but it’s way lower.

NCV shows power at the motor. But I was also probing the voltage on the solder and not exposed wire so maybe that’s me being retarded

>>1590031

>one triwing screw holding the case together
Niggers. I guess that keeps retards without tools away from the electricity. But they never envisioned retards with the proper tools like me!

>>1590031
Tried the switch on L, M, and H and each time I was getting ~14VAC between brown and the other 3.

Fuck. How do I fix this. Silicon caulk residue and nothing will stick to it...

I want to build a keyboard with some kind of screen on the caps so that the layout can change when I switch languages, preferably backlit somehow but not required.
Not considering power consumption, what kind of screen should I make the caps out of. First thought was e-paper but open to suggestions.

>>1590245
I mean to say... Paint and primer won't stick to it. There isn't any visible and the surface is too rough to try to scrap and sand it off... Not that sanding silicon works for shit in my xp...

>>1590245
It's on rough-sawn siding
use a wire brush to remove it going with the grain of the siding - up and down
use a regular wooden handle wire brush to get most of it
use a detail brush to finish the left over bits
solvents don't work well on dried silicone so just do it dry
the only thing solvents would do is soften the wood

My grill grates are (flaking?) and rusty. I cover this grill every time I'm finished with it, but I live in Tennessee and it's really humid here. So how can I properly fix and maintain these?

I'm putting a new plywood table top on my workbench. 3/4 inch plywood. I want to screw it to the (thin) steel frame from the bottom. How long of screws should I use so they don't poke through the top but hold down the board well?

>>1590535
You need to brush it every time after use and get it clean, then spray some cooking oil on it. Won't hurt to let it wet with oil. It will burn off next time.

>>1588901
No. R12 isn't a "blended" refrigerant to begin with, plus you'd have no way to prevent moisture or contaminants from entering it. You can buy 1lb cans of R134a from Walmart for less than $10.

>>1589066
Using propane in any appliance not rated for it (a) will create an explosion hazard, (b) violate the Clean Air Act (for you fellow burgers), and (c) probably work really well before it explodes.

>>1589069
>I can't use propane, since shit will explode
Well, at least you have a LITTLE common sense
>Also, r134a will be banned soon too
True, but the ban is on the production of new, virgin refrigerant. It won't be illegal to use and most manufacturers have a serious stockpile of it. It shouldn't jump in price like R12 did.

BTW what is this refrigerant you want going to be used for?

>>1589074
Somewhat true, the odds of your appliance just exploding for no reason are slim. The problem starts when it inevitably starts to leak. Ironically, the EPA has greenlit both Propane and Isobutane for use as replacement refrigerants (with many restrictions).

>>1589089
A viable option depending on what OP plans to use it for.

>>1589113
Any refrigeration wholesaler could order your friend a jug but it'll probably be expensive.

>>1589117
Just get a can of R134a with leak sealer in it.

>>1589138
Wow you're seriously overthinking this.

>>1589208
Fun fact: most of the R22 replacement blends contain a couple percent of isobutane to aid in oil return.

>>1589217
You already have a "heat exchanger" if you have AC in your car. It's called the evaporator.

>>1589253
It actually works quite well. Until it leaks.

>>1589934
This guy gets it

>>1589938
Then don't.

>>1590245
Dremel with a wire brush?

>>1590535
>>1590537
This. If it's pretty far gone, use a wire wheel on a grinder to scrub the crap off of it.

Question: does anyone have a recommendation for a mig welder/generator? I don't need any processes besides mig, and my only other requirement is that it be cheap. Everything I've found so far has been a five process machine for $15000.

>>1590535
Like >>1590537 said, clean it up and season it like a cast iron skillet.
>>1590536
1/2" will probably be fine, you may want to pre drill so it doesn't split the wood.
I put tape around the drill bit so it stops when it hits duct tape.

>>1589544
>>1589546
This, learn to sharpen your drill bits. I do mine on a belt sander

I'm changing my electric oven and the new cable (220v 40a) is too short. I'd need to tie it to the old one to make it longer. Can I just cut both open and fix them together like I would a normal 110v cable?

>>1590653
>I'd need to tie it to the old one to make it longer. Can I just cut both open and fix them together like I would a normal 110v cable?

For high power devices you really should look for a longer cable, as splices are the weak link and the place where a bit of corrosion leads to high resistance which can lead to heat and fire.

Can I use a long roll of 22 gauge wire to drop the voltage from a UK plug to roughly 120? I have an American phone charger and access to a couple 1000 foot spools. Don't have any money for a converter or new charger.

>>1590691

Yes. That's basically what is in an inexpensive converter. The better designs use triac inverters but that's only needed to power big things which are not legal in the UK unless you go to school and earn a big-thing license.

>>1590684
Hmm thanks for the advice.
I'll see if I can move some stuff around to get the oven closer to close the gap, remove its power cord and plug the old one directly into it without cutting anything.

>>1590691
The voltage drop will vary based on amp draw. This is kind of dumb. Sell your kitchen knife to a criminal for $20 or something.

>>1590691
Back of your charger will tell (you) if it works up to 220.

if I become proficient with Fusion 360 would I be able to get hired as a "designer", even though I don't have an engineering degree? Like I'd take already engineered things and transfer it into Fusion 360? Even as a part time job?

>>1588901
will
https://origingps.com/products/hornet-org1510/
include an antanna that will send out signals indicating its location?

and what are the specs that let it send out signals, and not just recieve?

>>1590859
Attach examples of your work to your resumé. You can always apply but they’re probably going to take a shitty candidate with the degree over you. But the key is to get your foot in the door somewhere, even if it’s part time or shitty pay, then you have a work history related to that design and will be closer in value to kid with degree but no real work experience.

Networking too. You gotta try your best to hide your power level and go meet people who may be able to connect you to potential employers.

>>1590606
Anyway, how to sharpen them properly?
When you drill zinc, wood or aluminum - my sharpening sorta works. When it comes to steel, it is two times slower, than new drill. When in comes to copper...Forget about it.

>>1591005
Thanks for the reply. This is a indeed a stupid question, but if I become proficient with Fusion 360 and have a solid grasp on the concepts behind everything, how impactful would that knowledge be if I were to go into schooling for mechanical engineering?

>>1590707
Make a transformer

>>1590560
Actually the ban for 134a is on new equipment charged with it.. if I remember correctly they don’t plan to ban production of the refrigerant... they created an accidental black market with r 12 that way and don’t want to repeat it...

Going to buy a welder to fix the rust on my car, planning to buy this 120v model. Will I be fine with 120v or should I nut up for 240v?

How do plumbers (the kind actually fixing bathrooms) deal with the smell of shit all day? Shit water just smells so fucking bad, how do these martyrs keep chugging along?

>>1591193
I'm not a plumber, but respirators work pretty well to filter out smells

>>1591196
These guys are no masking it with shitstained boots and then they get in their truck and drive away.

>>1589211
Harbor Freight has a lot of storage stuff for really cheap

Need something to fill in the gaps between wood in my shed.

Is there some like cheap sheets of rubber on amazon somewhere? Even if it's only like 1/16th thick that's going to be enough

>>1591274
get cardboard from local businesses

>>1591193
>>1591220
They get used to it over time. Watched my uncle smoke a cigarette while cleaning out our grinder pump once, now that's fucking savage

>>1591193
>>1591353
Yeah, basically this. I started doing commercial installs, just the thought of turds made me gag. Then the economy took a dive and construction disappeared overnight in my state, I started working for a company that installed and repaired sewage treatment plants and lift stations, I got used to it quick, but hated the travel so I started working for a plumbing service company. Now I barely notice the smell anymore, you just get used to it. For some reason though picking up my dogs shit too early on the morning makes my stomach churn and almost puke.

I have stupid question.
Why they don't add stinky gas to refrigerants

What's a good outdoor coax connector? Preferably one that can be easily disconnected. I live on a boat and would like to hook my tv up to the cable connection ashore. And I'd like it to be as easily disconnected as my shore power hookup.

You'll want a secure connection around water, so make sure it's quad-shielded and keep several wrenches around so you can loosen it.

>>1591485
Idk but I remember posting a few images with similar filenames so I don't think it's unique to iPhones

How can I mount a road shower to my cars crossbars on the roof? Its made out of ABS tubing, 4 or 6 inches in diameter.
I dont have a roof rack and im planning on using a cargo bag like the one in the picture, so the pipe cant take much space inside the rails.
what would be your solution?

>>1591290
Cardboard is going to deteriorate and whatever

>>1591169

Nigger, I’m pretty sure anybody can buy from Grainger or McMaster Carr. Northern Tool has a lot of wheels like that, you may have one nearby otherwise check the website because it’s 20xx.

>>1591153
As somebody who did a couple semesters of ME, it will help but that doesn’t mean you will automatically pass everything. You still have to take your basic bitch college courses, and the college will probably use different software (although I’m sure it’s very similar) and then you have all the material science and chemistry and testing that goes into real engineering instead of just playing with CAD software.

I mean it will definitely make some of the early projects easier for you, but engineering isn’t like lots of other STEM programs where you take all bullshit classes the first year, we were 3D printing stuff at the end of the first semester. So it might only be 2 courses before the rest of the class is basically caught up with you and by the 3rd or 4th semester everything you’re learning is new.

>>1589211
The one I posted there is actually the old model I think. Just go to Walmart. Pic related is the one I got a couple months ago. And if you want larger totes, go steal some from behind a Walgreens or gas station. CVS has these big blue totes they use that fold flat if you’re not using them so it’s real easy to stack a dozen of them. Technically it’s stealing but nobody will really care if you grab a couple.

>>1591274
Most hardware stores sell multiple sizes of 'foam rope', or you could purchase the stuff they use to protect plates during transport.
Foam sheets or bubble wrap.

Thin wedges of wood might work.

>>1589505
I used powdered charcoal on my filter on my house to clear out wierd smells from previous owner, worked great.

>>1590535
like all anons have said but use a oil like lard or butter for seasoning as it will help protect better then others, at least thats what I do with my cast irons.

>>1591545
>How can I contact R12 dealer?
I have about ten cans.
I also have some small cans with dye in them for R12 systems.

There are some annoying birds than won't fuck off and keep hanging around my house and I want to get rid of them. Can anyone think of some creative ways to kill birds?

I don't live in the US so guns are sadly out of the question.

>>1591693
Choke them to death by spraying R12 on them

>>1591698
So far I am thinking either some kind of compressed air powered projectile launcher, or a snare/other kind of trap..

>>1591693
Just get a cat or like a hawk as a pet

>>1591707
I have two cats, but the birds are too big for them to want to fuck with.

>>1591708
get better cats

>>1591712
Maybe he can try a bobcat or a mountain lion.

>>1591712
Get hawk. This will work better, since it would be able to fly.
>>1591693
>Can anyone think of some creative ways to kill birds?
Nope. Those fuckers are unkillable. They literally drank anti-freeze and came back for more.
>There are some annoying birds than won't fuck off
Which sort of birds?

>>1591698
>R12
No, better give me that stuff, I need it for AC.
I think R32 will work better for birds.

>>1591722
>>1591693
You have seagull problem, right?
No. Those fucks won't leave at all. If you start killing them, more of them will fly to this place.

So is it illegal to get a predator species as a pet that can deal with them?

You could always try putting some kind of owl looking things on your roof

>>1591734
>So is it illegal to get a predator species as a pet that can deal with them?
Having a pet which happens to kill them isn't illegal, no.. Can't think of what you'd get to do that though. Don't think we're allowed to own hunting birds. So cucked here.

Slingshot or BB gun

I have a bobsweep robotic vac, but no charger. I'm supposed to use a 24v charger - can I use something lower, like 15v? The battery is

Battery Voltage: 14.8V

is using a 24v charger on a 14.8v battery a way to charge it up faster?

Pls halp, reayrd here!

I need to match the paint of my walls to repair a hole. I filled it with spackling and sanded it down but how do I mat h the paint at the store? Just take a piece of paint to the store? How big does the piece have to be

>>1591840

if you rent check in all closets/cabinets/under sink as usually leftover paint is stored there for cases like this

>>1591796
You have to obey the exact requirements for charging lithium batteriues your you will die in a horrible fire.

>>1591796
>can I use something lower, like 15v?
no
>>1591796
>Battery Voltage: 14.8V
If the battery is a depiction of the actual battery, it's a four cell Lipo pack.
It looks like four 18650s in series.
The 14.8 volts is the 'average' voltage of the pack.
(four cells at 3.7V per cell equals 14.8V)
Fully charged Lipo cells are 4.2 volts and it's critical to stop charging at 4.2 volts exactly.
The charger must be capable of more than 16.8 volts to reach that charge level.
Additionally, using an incorrect charger on most batteries just damages the battery or doesn't charge at all.
Using the incorrect charger on a Lipo battery can start a fire, explosive fire.
If the vacuum has battery monitoring built-in using a similar to original charger would probably be fine.
If the missing charger does the monitoring, you need the OEM charger.
>>1591796
>is using a 24v charger on a 14.8v battery a way to charge it up faster?
No, the extra voltage is 'overhead' to get it to charge at all.
Post a pic of the charge port on the vacuum.

>>1591796
How the fuck two-cell li-ion can produce 14.8? It should be 7.4, and also it should be 5 wires when you have 4 cells (14.8). That battery is shady as fuck.

>>1591796

nope. 14.8V is the nominal voltage. when they're fully charged, they're gonna be just over 16V, so your 15V cant even fully charge them. find a 24V transfomer, or use 2 in series: 15V and 9V.

>>1591796
>>1591883
His pic shows 3 cables coming out, it must be +, -, and temp so there is probably a balancing board in there.

In that case do you just do a regular CC/CV charge x4? So 16.8V @ 1C?

Also yeah anon should look at the charging port because it might have some management system that asks for 18V or 24V or some shit, like my little 2s printer that wants 9V @ 1A.

I figured it maybe was square shaped with 4 cells and it’s hard to see from the pic. And it could have some balancing stuff all packed up in there, hence the 3 wires.

>>1591884
>it should be 5 wires when you have 4 cells
That's correct IF the connector is tapped for each cell.
Sometimes the monitor board is in the shrinkwrap with the cells so all management is done at the battery.
The third wire could be temp monitor to tell the charger to "STOP. I'M GETTING TOO HOT!" as suggested >>1591890

You can use butane or propane... just need to spark proof your system... no clue how you’d make r-12 but I suspect due to the chlorine content youd have a good chance of gassing yourself if you made a boo boo.

How do I use a multimeter to find amperage of a lighting fixture on a residential 120v circuit? I'm looking to install an occ sensor in my guest bathroom but I dont have any of the old paperwork for the lighting fixture in it; the sensors they sell at Home depot say they work up to 2A

>>1591545

>>1591404
Wouldn’t really serve a good purpose ... it’s not like natural gas with there’s a leak it’s going to be coming out of a pipe until it’s found, if a refrigerant system leaks you just lose what’s in the system which will then stop cooling and inevitably lead someone to discover that there has been a leak. With the exception of some industrial applications there’s not enough refrigerant in anything you’re likely to encounter in residential or like commercial systems to pose a real hazard unless you’re really unlucky and happen to be in a small confined air tight space... Might change with the new flammable refrigerants but I doubt it... Also the less weird stuff you add to that the better for the system in my opinion.

Hey guys, how royally fucked am I?

I was draining my water heater to flush the sediment like I usually do twice a year (its a full-size Bradford White 2015 model). Except this time I completely forgot to shut off the power to it before draining it. I realized my mistake about 45 minutes in and immediately disconnected it, so maybe 30-60min of exposed heating elements total.

Right now the tank is filled back up and I still have the power disconnected (20-30min after). So give it to me straight, how bad is it? Did I fry the elements completely? There's two one at the top and one on bottom. Also, now that the tank is full again am I safe to connect the power again or should I wait awhile?

>>1592143
>amperage of a lighting fixture on a residential 120v circuit?
It's based on the size and type of lamp in use.
Two 60W incandescent lamps ~1A
Fluorescent and LED 'may' not work unless specified for dimmer use.
(depends on the sensor)
Either would be less than the incandescent lamps.

>>1592185
turn power back on
if it heats water you're ok
if it doesn't heat the water, you burned out the element(s)

>>1592185
Only one way to find out, if the tank is full again you are safe to reconnect everything and fire it back up. Worst case you burned out your heating element and you’ll need to replace it, they are only about $25 and shouldn’t be difficult to replace on a newer heater. Are you on a well or do you have city water?

>>1592186
It's a regular non-dimming occupancy sensor and I have a fixture that has four 14W CFLs hooked up to it. Was thinking about getting LED bulbs for it anyway however

I'm kind of an idiot, but how would you go about putting an iron on patch on a backpack? It seems simple, but don't you need to put the iron on both sides of the fabric? I wouldn't be able to reach it through the bag.
If it comes down to it, how would I sew through the bag?

I ordered some carbon steel (1080) music wire from mcmaster-carr, after I turn them into compression springs, what kind of heat treat should they go for?

450F for 30 minutes then shut off/let cool slowly?

What's the secret to getting these things onto the back of a dryer?

I've totally stripped the screw on a worm clamp trying to tighten it and ripped the (semi-rigid) tubing in the process. Still just pops right off at the slightest bump.

I've got a shower coming from the bath tap kinda like this one. For some reason, you can't mix hot and cold, it's either one or the other; and once you make it cold you can't turn it back until you shut it off and on again. Any idea what's up with it?

>>1592252
Sounds like you don't have the right size clamp or tubing for your dryer

>>1592306
It's pretty and there is a huge margin on it, so you should be able to get a nice deal. It's not always gauged at the same thickness, so it can be a little trickier to install.

>>1592205
>It's a regular non-dimming occupancy sensor
It's not whether the sensor is a dimmer or not.
Some sensors use a trigger circuit similar to a dimmer turned to full brightness instead of acting like a flip switch.
Some lamps act funky, flicker, make buzzing noises, or generally just don't like these sensors.
LEDs may glow all the time due to leakage of the sensor circuit.
Other sensors aren't this type and 'may' state explicitly "May be used with LED, fluorescent, or incandescent lamps."
The only way to know for certain is to install it and test the operation.
If it's rated for 2A you are not likely to overload it.
That's enough for four 60W incandescent lamps.

How can I sharpen my delica 4 with a mini whetstone?

I have this


https://aliexpress.com/e/gjtMcta

1000 grit

>>1592382
By buying a bunch more grits, and working your way up

>>1592382
Shitty fucking 4cuck thinks I'm spamming. Can't link

>>1592384
Can't I just spend more time on a finer grit?

Dimensions are like 6.3 inches long .8 inches wide. Does size matter

I am making my own mini curtain rods.
I need help finding some appropriately sized ball end cap things, like pic related.
I am using 1/4" brass tubing.

Essentially I got some decorative hand towels I want to hang on the wall, and the ends of the towel are sewn in a way that I can shove a 1/4 rod through them. I want to put the rod through and hang them like a wall scroll type thing, but I cant find any caps that would be suitable for something small as 1/4.

>>1592385
>Can't I just spend more time on a finer grit?

No, you are reprofiling the stock blade angle anon. 1000 grit is to put a mirror polish on you dingle. youll spend hours and hours and hours and get nowhere.

>>1592409
I have a decent edge probably I'm doing this alongside honing, I dont want to completely put a new edge on it.

Let's say I did though, let's say I bought a 400 and 800 grit as well, will those three be sufficient? Even with the miniature size of my 1000 grit?

I have leather strop as well for honing

>>1592414
>I dont want to completely put a new edge on it.

You pretty much have to take the shoulders off the stock grind, unless its a FFG variant.
But youll do much better by taking the shoulders down with 400 first.

>>1592419
I'm going to be honest I'm new to this and I dont even know what you mean by shoulder. I watched 2 videos on sharpening

>>1592420
Horrible picture, but the first one I found
From the factory the edge you have is slightly concave from being ground on a round grinding wheel in a machine.

The first time you hand sharpen it, you are re profiling the whole end of the blade into more of a flat grind. You will never be able to match the original grind with a stone, so it can be a lot of work. Thats why course stones exist to move metal.

You sharpen the primary back until the "shoulders" are gone and its a flat primary grind.

>>1592424
Wrong picture, I meant this one.
Absolutely horrible but gets the point across.

>>1592424
So is the black in that pic the factory and the green that I'm doing?

Should I hone the blade a lot first to see if I actually need to sharpen and put it off for as long as possible? Maybe I can get away with keeping it the same. I dont want to ruin the edge

>>1592427
>So is the black in that pic the factory and the green that I'm doing?

Thats a bad picture, showing a flat grind going to a convex grind.

But the principle is the same, the factory grind will be concave and if you want to sharpen it, itll have to take the shoulders down to make it a flat grind.
You can see hollow grind in this pic and how it would have to be re profiled in the same way looking at the other pic.

Putting it off isnt going to help you, you need to learn to sharpen sooner or later. Just do it, maybe buy a cheaper knife to start on though VG-10 is pretty forgiving.

I say just buy a Sharpmaker sharpening set and be done with it, they are designed to work great with spyderco stock edges, They reprofile them really quick

Not for long if you are getting into the knife hobby.
And better or worse is subjective depending on what angle you actually put on it and how you plan to use it on.

But the knife will dull, period. And you will need to sharpen it. Look up different angles and sharpening in general and youll get a much better grasp on the idea as a whole.

>>1592445
>getting into the knife hobby

I'm not. Im fine with just my delica, I might get wood working tools soon though.

I guess I'll just do the old school whetstone hand method. I still dont know if the whetstone I have is usable or not though with its size.

What size whetstones should I get? Ive got the 1000 assuming its usable. Should I go 400 grit 800 grit - 1000?

Besides, most discords posted on 4chan are to DOX users, but (you) already know that.

That transmitter should easily be usable well beyond that distance.
C4, C5, and L1 are somewhat critical.
You may have it tuned incorrectly and are picking up a harmonic.

>>1592521
I don't know if this circuit is legit, I've seen larger circuits I thought maybe it has a small range since it takes low power, I cant calculate the value of the capacitor since its too small (my cheap multimeter can't measure it) so i cant determine the frequency i should use, i just tune until i get something at 92 mhz.
I want to test other circuits but most of them are not verified and Iam not into radio science.

It is the battery that is listed as a replacement for the OEM one. I don't need it super well charged - I just want to get it up and running and test some functions. I would assume the wall wart doesn't have all that protection circuitry. It's just a wall wart ( the missing one ) .

>>1591883
>the extra voltage is 'overhead' to get it to charge at all.
Then why go all the way up to 24v to charge this thing.. like wouldn't 18 or 20 do the trick?

Would 15v get me a half charge?

>>1591884
>>1591891
>>1591965
battery from their site.

The vac asks for 24v @ 1A - but I don't want to drop $20 on a charger - I don't even know if this thing works. I'll get the charger if I need to but was hoping I could get it going with my own power supply or something.

I have one that will do 24v @ 1 amp - but I don't have an easy way to connect it to the power jack ( I guess I could cut off the connector from the 15v one ). I can get to the battery pretty easy, but it sounds like I need to be using the onboard circuitry so I don't burn the house down. That means taking the whole fucking little beast apart. Which I will definitely do - just hoping for an easier answer like

"you can charge it at 15v, it just won't get full "

That would be ideal for now.

>>1591883
Could I hook this up it will do 24v 1A (1A is max ). I guess I would open it up, and clip in just after the plug receptacle, since I'd rather not cut up the 15v laptop charger that has a matching plug size..

>>1591889
I sort of hate electronics, as I struggle to understand it. I do get you can add them in series. But shit like... How can something "draw" too much power/amps. Like I get the water metaphor, but how does the waterwheel somehow suck up so much water it causes problems upstream? ( isn't this what is happening when the bulb draws too much current? ). I mean why doesn't it just fucking go slower since it has less energy to work with.

>>1592569
Can you open up the case of the thing? Where the charger plug in the vacuum or whatever it was, maybe you can pop a plastic cover off and find a connector or soldered point inside and you can clip the power supply probes to that

Or take the 15v and go straight to the battery pack and you should be able to get like half charge out of it.

>>1592571
>But shit like... How can something "draw" too much power/amps

Always remember that volts, amps, and resistance (more accurately, impedance) are always related.

If the power supply produces too much electrical pressure (volts), the load will draw too much current.

If the impedance of a load drops too low for some reason, it will draw too much current.

In practical application, overcurrent situations are almost always a result of a failure of some component, or a poor design that allows it to happen in certain circumstances. What exactly happens afterward is entirely dependent on what you're working with. Ultimately, though, anything without some kind of protection (fuse, breaker, etc.) tends to just burn out whatever component is generating the most heat.

Friendly reminder to be careful around electricity.

How do I know if it’s the correct physical plug dimensions.

>>1592922
Measure it. Or type in the name of the device + charger. There’s normally only a handful of sizes of those power supply chargers so it shouldn’t be difficult. I’m sure your Chinese crap doesn’t have a custom built proprietary charging system.

>>1592922
>How do I know if it’s the correct physical plug dimensions.
measure the plug on the laptop charger you have (you said it fits) or look up the specs for it.
order one with the same dimensions and polarity.

I've just used this to charge a 12v sealed lead-acid battery. Now my voltmeter reads the battery as having 17v. Have I fucked up?

What did you measure it with?

>>1593066
A fairly inexpensive Schneider analogue multimeter. Also, what current should such a battery draw on charge? More than 500mA?

So this charger is suitable for this kind of battery? The reason I ask is that I read that it should take about 12 hours to charge but after less than 8 hours it's appearing to be fully charged. Should I hook it back up and leave it overnight, or will that damage it?

how do i discard of old stale gas?

>>1593107
>So this charger is suitable for this kind of battery?
The pic is so small it's difficult to tell what it is.
It looks like it has an 8 on the front implying 8 Amps
If it for auto batteries, it's not really ideal for such a small battery.
A 'wall wart' style charger of 1A or less would be a better match.
It that's all you have, it's what you have to use.
>>1593107
>Should I hook it back up and leave it overnight, or will that damage it?
Charging at 500ma it should reach a full charge in an hour or two depending on the state of charge when connected to the charger.
Leaving it overnight would likely damage it.

I say all of this without knowing what kind of charger you have.
If it's a 'smart' charger it may be possible to leave it on indefinitely.
Smart chargers monitor the battery closely and can estimate the capacity and adjust the charge rate accordingly.
They also know when to go into 'trickle' or 'maintenance' modes for keeping the battery at the correct state of charge.

What is the device the battery is used in?
Alarms and such have dedicated chargers most of the time.

>>1593126
Yeah it's a car battery charger but would that make a difference? I was under the impression that it was the same underlying technology in this battery of mine as in car batteries, which means the charger should give the battery the voltage it expects, is that right?

I'm making an assumption here but it could be wrong. I'm sure the old charger that came with it didn't reach anything like 500mA when charging this same battery.

I don't know if it's a "smart" charger but if it's meant to be used with a battery that has a defined charge cycle, then wouldn't it have to have some kind of charge level monitoring going on? Or are "dumb" chargers (i.e. PSUs) a thing?

>>1593130
>the charger should give the battery the voltage it expects, is that right?
lead-acid chargers are current limited and voltage limited.
The charger for the small battery is probably limited to a few hundred milliamps.
The auto battery charger is designed to stuff up to 8 amps into a several hundred Ah battery until it reaches a level off point.
The level off point of the auto charger is probably more current than the standard charge rate for the small battery.
They both aim for the same voltage level but the car charger is shoving it in faster than the little battery is designed to accept.
And the car charger is still pushing when the little battery is full.

>>1593130
Harbor Freight or Northern Tool or one of the other usual suspects will have small battery tenders for <$25. That may be the way to go. You can leave the tenders on indefinitely because lead acid batteries do well with the little trickle charge.

If you’re using a big old school charger for car batteries, yeah it’s probably too powerful and may not shut off at the right time.

Pic related works well for my small 4Ah scooter battery and can even charge a car battery (slowly) and goes on sale for $25 a lot. Charges at a fairly low current and goes into maintenance mode as soon as it gets up there in voltage. Only downside is the smart chargers don’t like to charge real flat batteries, it’s a protection thing so people aren’t forcing a battery with a dead cell or other charger, so make sure you don’t run that battery you have under 12.0V. Plus discharging so low isn’t good for a lead acid battery.

There’s a website called battery university that is super good at explaining anything you would want to know about charging and use.

https://batteryuniversity.com/learn/article/charging_the_lead_acid_battery

>>1593130
>I'm sure the old charger that came with it didn't reach anything like 500mA when charging this same battery.

These frequently go on sale for $5 - $6.
I have five or six of them maintaining different batteries.
They 'will' charge a car battery but it would take week(s)
This would be fine for charging the 1.2Ah battery. I may take 12 to 24 hours to do it but it won't damage the battery doing it.

Is it incorrect to refer to equipment lacking a grounding wire as "ungrounded"?

>>1593354

Now I'm going to worry about the one I've had on my garden tractor battery since 2011.

>>1593646
The reviews look good. For the price it’s worth a shot instead of risking it with the ancient one. But I’m not sure how the thing even works, my “4 Amp Fully Automatic Microprocessor Controlled Battery Charger/Maintainer” displays the voltage and as it charges, it gives the thing pulses like shoots up to 14V+, sends an amp or two to the battery for a few seconds, then drops back down. And then it goes into a maintenance mode once it’s full. It has a regular and AGM mode too because every battery chemistry is a little different. If you have a multimeter you can keep an eye on the charging with whatever charger you use, but if you find a decent “Smart” charger that is still low current, or even a higher current one if you want to use it on the car but is smart enough to not charge a 1.2Ah battery at 20A, that would probably be the best route.

Otherwise use the ol’ google and search for what other people are using to recharge their small lead acid packs. Riding mowers, smaller generators, little scooters, other yard equipment often use small 12v batteries and some may need a dedicated charger so look into those.

Depends on whether it was designed to be grounded or not.

Neutral and 'earth ground' are physically different but the electrical difference (volts) should be as little as possible.

Got this old generator off a junk pile and took it apart. Found pic related. Anyone know how this couldve happened? Is this due to knocking? Also found lots of rust in the fuel tank and old gummy gas in the carburetor.

>>1593921

depends on what kind of knock, there are a few;

detonation
fuel knock
bearing knock

so im going to say its possible definitely but unlikely. in this case its more likely just from fatigue. detonation is possible but in my experience the piston is the most damaged, never seen a snapped rod in anything other than reallllly houred out generators (40k hours+) or in one case an injector that had failed and filled the bore full of fuel causing a hydrolock scenario

just curious, do you live near a lot of boats?

Hi Jerry

Hello, Jerry

You're young and welding is gonna be in demand for a long time. It is profitable and the skill often comes in handy (depends on your life).

As for the health risks, I think we live in a time where bureaus and authorities like to show activity by caring about everyone and everything. What I want to say is that there are so many work safety regulations concerning your health, it is very risky for a company to not provide relevant PPE. Nobody wants to get fucking cancer; and technology has come a long way. PPE will 100% protect you against fumes/gasses and ultraviolet light. Most of danger people were in during my welding period came from them being lazy retards.
>too lazy to take gloves off when grinding or drilling
>too lazy to put on glasses when grinding so you just look away :-)
>too lazy to put on a helmet for a tac weld so you just safety squint and kinda look away


There are also the rare cases where you are welding a giant water pipe from the inside and some onsite technician decides you need your fair dose of good ol O2, so he brings out an oxygen cylinder...

Also be careful to not let heat radiate on your balls. People often forget because it doesn't hurt.

I'd say go for it if you like the labour of it.

I bought a new 12V motorcycle battery, filledit to thz upper line with acid, and then began charging it. The manual said that the battery is already fully charged but it's good to charge the battery for like 5 hours before using it.
When i started charging, i measured 12.54V. but suddenly after 3.5 hours i measured 18V. I immediately took the charger off the battery. I measured 15V on the battery and 18V at the charger. I was like wtf and let it sit for a couple of days. The battery stabilised at 12.54V, and i measure 12V on the charger when it's not connected to the battery. But as soon as i connect the charger to the battery i measure 15.5V and keeps increasing slowly.
I'm afraid that it will or already damage the battery or charger. Can someone explain what's happening? Pic related my battery and charger

>>1594214

isn't that normal?
car alternators hit about 19v to charge a battery?

I live close-ish to the coast, I guess, but the generator didn't look very corroded as I would've expected from living on a boat.

The generator actually looked kinda new - hence why I picked it up to try to fix it. It was a briggs & stratton 5000W.
Don't think it was a bore full of fuel either, as it's got a carburator and not fuel-injection.
Piston is also pretty beat up; a part of the outer portion of the metal (where the ring grooves are) is completely shattered

depends, there is no DC rating.

if the switch is on the AC side then it will be fine, if it's trying to switch the output (why? i don't know) then its unknown because no DC rating. switching DC is harder because no zero crossing.

you don't have to match the current, the new rating can be higher.

>>1594509

but are they connected to anything?

>>1594515
The switch is the one on the left

>>1594517
ok so you need something like
spdt, centre off.
if it says on-off-on thats fine
if it says (on)-off-(on) that is not fine.

just like both you posted are the same mechanism which is good.
but the DC ratings are slightly under. probably you will get away with it it seems like control so i wouldn't expect any huge current flowing.....but you never know.

>>1594497

>it's got a carburator and not fuel-injection.

oh sorry if i was unclear i did notice it had a carb and was unable to fill the bore with fuel, i was just rambling however irrelevant it may have been

>I live close-ish to the coast, I guess, but the generator didn't look very corroded as I would've expected from living on a boat.

the reason i asked about the boats, and this is just a guess, but it may have been on a boat running in shallow water, fell off the boat and hydrolocked

>Piston is also pretty beat up; a part of the outer portion of the metal (where the ring grooves are) is completely shattered

well in that case im going to go with fatigue as my final answer.

rod bearings first to go, causes a knock, connecting rod starts vibrating, which causes stress fractures and eventually just seperates entirely. will also causs piston to wiggle in the bore and cause damage as you describe

What does .750 silver content mean?
75% Silver?
Tried googling it but the results are so misleading

>>1594212
thanks friend

https://youtu.be/G0TZLSvFOQ0

>>1594552
you are correct, it is the purity (in parts per thousand). so, if the country origin is in North America or Europe 0.750 or 750 silver is 75% pure silver. therefore, Chinese silver that's rated as 0.750 or 750 silver is somewhere between 0% and maybe 30% pure silver.

Oh, my battery is only 3Ah, so i need to find a charger that supports that i guess.

I have a balcon that is kinda rotting. The concrete is exploding and the iron armor under it is all rusty. I've read how you should recover it, clean the concrete around, apply rust preventing dedicated product and then cover it with special fast grip concrete. Sadly i have no real experience on those jobs, beside covering a wall with concrete 10 years ago. Is it worth risking?
After i should impermeabilize the balcony if i understood correctly, but that seems easy, just apply the product over it and that's it.

>>1594656
dunno man, but encasing wood or iron when it hasn't been cleaned and treated properly can cause it to rot/rust faster. you really need to know what you're doing i think, especially for something that can kill people if it fails. might want to scour youtube for a how-to or find an episode of This Old House, or similar, where they teach you how it's done

>>1594658

I see a lawlsuit in his future.

>>1594658
Yeah that's my main concern, that it will look ok while it's rotting inside and everything crumbles costing me 10x what would have been the original cost.
I watched all the tutorials in my language i could find (so that the products they use can be found where i live) but it seems like a lot of the skill involved isn't incredibly high but only comes from direct experience.
My house is basically all like that, and i wouldn't want to pay for all of those works. But maybe i should stick to other outside walls, that only have esteticals deficits. If i fail, at worst the finiture will come off.
>>1594660
All on my property, so it would fall on my head at worst. But i agree with your concerns.

I have a short wall outside with this finiture on it that is detaching, leaving only bricks. I read it's a pretty simple job to do, gotta mix concrete with sand (depending on granulometry it will get rougher or more slim) and use a dedicated manual machine to splash it directly on the wall.
Is it true? Am i making basic mistakes? Does it need an actual first layer of concrete to grip on it?

>>1594992
>do you think McMansion?

I paint houses, and my definition of a McMansion is that house where you say "please unlock all the windows so we can paint them", and they can't find some of them, so we have to go in the house and show them the weird stairway and doors to those rooms they don't even know they have.

In other words, sane people don't need all those rooms. A living room that is never used. A dining room that is never used. All those upstairs bedrooms that are never used. Those "game rooms" over the garage that are never used.

A proper house is always a bit cramped, so you have to toss out shit you never use. If you really need a room for woodworking and another room for your machine tools, fine, but if you never go into one of the rooms you have fucked up.

>>1594992
kinda ugly, but it might be ok depending on the materials used
i mean, if the siding, roofing, windows and doors etc are all budget-level it's going to look like shit
if the location is nice and it's made with nice materials it might look pretty nice

Hey I was posting a while back about my smart panel and the wiring. Got all the keystones on, and the coaxial set. Now I've found either my switch is faulty or something else is going on. I only get internet in my office and thats because I have my router there. Any other room that I hard wire goes directly from wall jack->device and while the they're connected there is no actual internet access. The office goes wall jack->router->computer. If I wire it straight from wall jack->computer then no network access. I'm not sure what is going on here. Any ideas?

Current setup is Modem plugged into port 1 on the switch. Then ports 2-16 connect to the wall jacks in the rest of the house. Seems straight forward and like it should work, but none will carry the internet connection unless it goes into the router first. I could throw the router into the closet, but that defeats the whole purpose of the switch.

>>1595039
a switch is not a router

you need to go modem -> ROUTER -> switch -> clients

switch is the thing that allows the talking to one another, but it isn't smart and doesn't know how to share (route) internet to each of those separate clients. if you plug the clients and the ROUTER into the switch, the switch just needs to spread the router's love around, and the router is responsible for talking to the modem and then routing that info back to the correct client.

>>1595039
>>1595045
as an added tip, when youre doing small network setups like this, you should basically consider the modem and the router as one device. the router should always receive the modem and then be responsible for doing the networking from there. if you dont have them in the WAN->MODEM->ROUTER configuration then you will not accomplish what you want.

pretend the modem and router are a single device and they can only be used in MODEM->ROUTER layout. then go from that as square 1 for the rest of your networking plan.

>>1595045
>>1595048
Thanks. I totally misunderstood it then. My ISP provides a combo modem/router, the same one that is in the closet now, but I had them disable the router part since I used my own wireless router and my previous house was much older and didn't have anything like jacks in every room. I'll have to call them up and see if they can enable the router part and that should fix it then right? It'll go modem/router->switch->rest of the house.

>>1595052
yeah that would work fine as long as you remove the router that is currently in use. two routers in the same setup is asking for trouble.

fwiw, its important to remember that a "wireless router", both the kind that your ISP has provided [that PART of it, i should say] as well the incredibly common/popular kind you would buy for yourself - these are dual function devices. much like people with those ISP provided modem+routers dont understand they are a dual device.

a normal aftermarket "wireless router" is actually a router and a wireless access point. the routing function is separate from the wireless function. they would work independently if they were separate devices (and, of course, you can buy them as separate devices). in this scenario what is really happening is:

modem->router function->wireless access point->wireless client

simultaneously;
modem->router function->[optional switch]->wired client

youll notice that the wired client does not interact with the wireless function (why would it?) and that the wireless client doesnt access with the switch (it goes directly from the access point function/device to the routing function/device and then out to the modem and then the internet.)

i mention all this so you can make an informed decision on what to do next. you can have the ISP turn the routing functions back on (which means they will be turning on the routing AND wireless access point functions!). or, you could rearrange your current setup and have your current router do the same thing. youve indicated you wont be doing that, and im not sure why, but im guessing you have a reason.
(cont)

but, if you wanted to continue to provide wireless internet to wifi clients, you can. your two options are to let the isp device do it all, or you can turn your current wireless router into an access point only (usually called AP mode). this means it does not route in the traditional sense, it simply bridges wireless clients with the rest of the network. you can almost think of it as a wireless switch.

this is how large (usually mesh) networks handle it. you just slap up APs all over and make sure they are being properly served. clients hop on to the most convenient AP and then the AP joins them to the network and thus the internet.

this is why all of your clients saw the LAN just fine. you were all on the switch and could all talk to each other. great. but, the modem cant talk to more than one client at a time. and when the modem is in the switch with all of those clients, NONE of them work because none of them are properly configured.

with a router, the router makes the modem think that it is the sole client. then the router assigns identifiers to all the LAN and WLAN clients that it is connected to. it takes the information and requests and gives it to the modem as if IT wanted it, and then when that info comes back, the router knows which client asked for it and where to send it. thats the smart part of it. an unmanaged switch being dumb, thus all it does is act as a switchboard (hence switch) and allow a wire connection from client to client in a meaningful way.

does that all make sense toward reconfiguring your setup to do what you want?

>>1597293
Spray. If it's to high to reach hang a hotdog or similar sixed piece of meat 1/2 inch over a tub of soapy water nearby, they will attack it pretty fast especially this time of year and they drop to take off so instead of falling some in the air and taking off they drop into the water and since there's soap in it they can't climb out with the surface tension. Eventually the hive will run out of wasps.
