hey /diy/
there wasn't a /sqt/ or qtddtot so I'm creating one with this post.

My stupid question: I have a rough idea for an engineering project but I'm not an engineer. Eventually I'll present my idea to an actual engineer to analyze and correct the numerous mistakes, but before I do that - how detailed should I get with the rough draft of my design? Should I attempt to design it in FreeCAD or would isometric sketches be sufficient? Can mechanical object CAD files be downloaded somewhere so I can "easily" put things together without having to design every part by hand? Thanks for any information you can provide.

>> No.1510882

If all you have is a rough draft I'd just make a clean and clear sketch or set of sketches. If you go "designing" a bunch of parts just by your best guess it will probably just make more work for the engineer.

Can you be more specific here? Are you inventing a jet engine or something simple like a hammer?

I have an electric scooter, and I want to secure second battery.
Electrical part works fine, I connected in parallel with a fuse. Good enough.
But I don't know how to secure battery on the steering wheel. I tried screwing food container, but PP plastic is too fragile and battery cracked it.
What should I use? I don't want to do a box myself, since my woodworking and metal working skills are garbage. A bag?

Alright /diy/ I got a fucking problem, big fucking problem
I was fucking around in my shed and I found an old Dewalt DW281 screwgun that must have belonged to either my dad or granddad
It's old and dirty and beat up so I say what the fuck I'll fix it up and "restore" it. I go inside, clean up the exterior with toilet paper and baby wipes and then I decide to test it. I plug it in and pull the trigger, I hear an extremely faint humming and after a few seconds smoke starts coming out of the drill. I open the drill up and I find a fucking colony of Dirty Ant Whores.

You don’t have the navigation screen, do you? If not, it should be simple enough. Head unit, faceplate kit and wire harness adapter for your car, speakers, sub(s), amp, power and speaker wire. They sell sub kits that will come with a matching amp and all the wires and connections, the other speakers should be simple, the wiring harness to the head unit is the one thing that people get caught on their first time.

And you will be straight with one battery unless you’re going full nog.

what does "ventilation" mean. And how long are those electrical cord runs?

>>1513376
I'm not an electrician, so someone correct me here. Personally I would:

1) find the circuit breaker for this cable - see how many amps it is
2) you want heavy duty extension cords, and you want short runs. you can find ones that are rated for 20 amps.
3) that power strip is going to fucking fry. Go buy some real outlets - they are cheap - and wire them up.

I think it is a bad idea to have all that crap on the same circuit, you'll probably blow it all the fucking time. or go away for the weekend, come back and find your food spoiled. or apartment burned to the ground.

either you are renting in which case, call your landlord or

>> No.1515330

it isn't as easy as that. normally you add an amplifier, which requires an additional power line from the car battery. So you have to get 10 ga wire through the firewall or whatever it is called. Then run wiring from the head to amp to speakers. You can probably do it yourself, but be prepared to watch lots of videos and invest a bunch of time into it.

Gold-plated connectors aren't supposed to oxidize. Either your connector is just filthy (use solvent and some elbow grease) or it is damaged. In the latter case you can try scraping the shitty contact gently to get rid of the black crud.

Either way, it's pretty limited what sprays can do.

Meh, the wiring isn’t that bad. It’s one audio cable and one power cable. Normally we would end up tucking the wires in the carpet along the center console and trans hump. Last one I did it on was an older BMW so the battery was in the trunk and that made the power thing way easier.

I believe you - all the stuff inside the car was easy, but going out to the battery was too intimidating for me. I did an upgrade to separates for my speakers on my own, but the battery connection was too much. I took it to a professional, and they fucked it up too - they nicked something going through the firewall I guess. Audio shop said it couldn't be them... I took it to dealership since it happened the day after I got this done, and I wanted some proof it was them. Dealer found the issue, audio shop covered it, all worked out in the end.

Yes. The amount more the power supply draws is mostly a factor of the efficiency of the supply.
However, the efficiency of the supply varies by the load placed on it.
'Usually' most efficient at near full load.

Depends on the load it needs to carry, the dimensions involved, and how it's used to support the load. And do you mean solid or square tube? Wall thickness matters in the latter case. Specific alloy matters in principle, but I'm guessing mild steel.

Seems like overkill. I'm hoping to keep it light to allow the woman homeowner to use it.
Green being the square steel (yup, hollow - I was thinking 0.12") and red being where it'll rest on. My gut says 3/4" would be fine, even likely 1/2", but I don't have anything to base that off of.
It's a small deck that shouldn't have more than 2 people standing on it at a time, but I'd like to exceed that for safety sake. It'll certainly never see a heavy load like machinery.

If you are able, I would cut a few inches of the wood on all sides away to give it a clear lip to rest on, this should prevent future problems after repaired, at least major bowing problems. I would personally suggest some plywood backing instead of 10 different pieces of wood. If you want this to be easier on yourself, discolor the top a bit and don't put real weight on top of it. at least that's my two cents on it.

That sounds counter-intuitive. I'm reading 'cut the door so it misses the jamb'
See this pic above - I'm planning to scrap all those 2x4s on the door, lower that 2x4 framing (thankfully it's just screwed in place) and weld a frame for the door.
That steel frame running underneath will take out any sag - my focus is how thin of metal can I go with and keep it safe while keeping it as light as possible.

It's actually underkill. That's the result without any deflection limit, meaning that it's using the plastic section modulus. That is, that's the size of tube that will barely hold the load without failing outright, and it will be permanently and seriously bent after a single load cycle. The deflection-limited column is fairly close to my estimate for a maximum stress of 36ksi (the yield stress of typical mild steel). It probably either has a modest safety factor or a larger safety factor relying on the somewhat greater strength of formed steel.

Some factors to consider though. That calculator is about a single beam carrying all the load. The replacement bracing will need multiple beams to reduce the unsupported span of the planks to an acceptable amount. 16" is a standard floor joist spacing distance.

Another thing: the stiffest part of a structure carries the greatest portion of the load, proportional to its stiffness in relation to other parts that could carry the load. Running any tubes along the 60" length won't do much. They would help distribute the load between the 30" tubes, but if they're the same kind of tube, it won't distribute very much because they would flex twice as much for a given load, and resting one end on the 30" span would add the 30" tube's flex to its own. The ones you have running along the 60" edges don't do much at all structurally, since the support boards are right there. Something like pic related would be a more efficient arrangement. The plank ends on the right don't need a tube under them since they rest directly on the support board.

A standard design point for live loads in residential floors is 40 pounds per square foot, so right on your 500 pound estimate load, but that's applied continuously rather than at a point. However, for something this small, I'd go with a point load consideration. A person jumping produces a load on the floor of several times the person's static weight.

>> No.1519080

A couple more considerations: Steel is very strong and cheap by metal standards, but cheap (mild) steel's strength to weight ratio is not very impressive. Aluminum tubing could produce equivalent strength with a larger but lighter (and more expensive) tube. A structural alloy like 6061 would be suitable.

Also, how do you plan to connect the tubes to the planks forming the surface of the deck? Bolts/screws through drilled holes would work, but the holes would reduce the strength of the tubes.

True, I had initially approached this as a welding project and don't have the capacity to weld aluminum. 6061 would be best for the application - especially when you factor in rust.
That's another good point the calculators couldn't factor in. I intend on screwing from the underside to keep the clean appearance.

>is there a diy method for clearing a house of ants?

I've tried sprays and baits and the technique that actually works for me is this: either buy borax powder in the laundry detergent section, or buy boric acid; both seem to be very effective. Mix about 1 part borax or boric acid with 8 parts sugar, then add just enough water to make it syrupy.

put a small puddle, less than a teaspoon, in the ant trail. within hours there should be hundreds of ants feasting on it, and carrying it back to the colony to poison the larvae and the queen. don't kill any of them because they'll die later on.

it seems that a day or two later a few ants show up. my theory is that they were far enough along in the larva state that they were not being fed, so they developed and came out. you can kill these or ignore them. in another day or so you should be ant free.

Grout, like other cement based products, is very porous. You can clean the surface, but good luck getting all the foreign material out.

Your best bet for color match is to grind it and then re-grout that area with the same grout you used initially, though this is no guarantee. Old grout is dirty and therefore usually darker than new grout.

Another option would be to try to flush the area with paint thinner. Absorb the run off as much as possible, and repeat. You will only ever fade the stain using this method.

Muriatic acid is another thing to consider, but I'd only use it as a last resort.

Good luck.

Since it's only 1.25" aluminum, I'm more concerned with compromising the structural intergrety by drilling 12 holes in each 33" piece - or 24 if we use bolts.
>>1521076
>the point it will fail is when someone accidentally steps on it.
Doesn't matter. The downward force is applied to the aluminum which is seated in the 2X6, so no harm, no foul.
>>1521100
We went with #10 self tapping screws and nuts and bolts in the front (pops being controlling and making everything into an all day project. Still love him tho)
A little putty and paint and it'll look fine. My calculations are the aluminum should hold 2,500 lbs total. With holes, the limit is 3/4 of that. For safety sake, cut that by 1/3. So we still have a weight limit of 550lbs. Unless you're moving a fridge or have a couch on top, it came out alright.

unless he wants to put something overkill on it, almost all of the stress points will be on the sides that don't get cut at all, there should be very little issue with these and stress.

lets put it this way, the flay side that is attached to the wood, there is a good chance I could bend that with my hands much less body weight, but even one of those sides the way they are, I could jump wand kick down with all my weight and its unlikely to do significant damage if any at all, and given you have 5 of them bracing the thing I honestly doubt they would fail structurally at all. as long as he not hogging out all the material from side to side to put a bolt in itat its at most a 1/4th the width the hole... there should be no issue.

A cheap stick welder would be appropriate. Don't get the very bottom of the barrel, but basic machines of decent quality can be had new for pretty cheap.

Drum roll please. Walmart. Yep. Only for one reason. They keep in stock 5/64 6013 or maybe it's 6011. Either way either of those rods will work will over less than clean steel (you steel should wire wheel or at least wire brush it) and being so small they will help keep a noob from accidentally blowing through because of the low amps they can run on. They also allow to weld vertical down, again good for a noob. Get an appropriate extension cord for your new machine. AKA heavy duty.

Jesus man who cares if the weld or the parent metal broke the puzzle concept still works.

Put a bunch of weld on it for extra reinforcement.

Out out if the position it was in before. Where it worked is the only appropriate spot for it to be again. A 1/8 scab plate will throw it out at least 1/8. If the gate is 3 times tallaer (verry common ratio) than wide that's 3/8 out. Pretty bad.

One of mine doesn't have a card slot but it does have bluetooth.

I was working alone trouble-shooting a bad ground or neutral.
>difficult to tell which until the actual problem was located
I noted a voltage of a couple of volts between the ground rod and a test rod I had stuck in the ground a few feet away.
I found the voltage varied depending on which breakers were on in the panel(s)
I went to the panel room and turned off all double pole breakers in all three four panels.
Then I started flipping them back on on at a time and walking the fifty yards it took to get from the panel room to the exit on the other side of the house and back around just to read the meter that was five feet away from the panels but outside.
After all the trips (probably twenty) back and fourth I decided I was going to have a meter I could read remotely.
I ordered it. I tested it. I was happy with it.
I haven't needed it but if I do, it's there for me.

Pretty sure the vacuuming is just a precautionary test as leaks in refrigeration systems can sometimes occur while under vacuum but won't appear from being positively pressured.
t. work for a custom refrigeration company and the only time we vacuum the systems is when we put it under vacuum to and hold it for 10 min to see if it maintains the same pressure level.

>what's the difference between hot wood coals, charcoal and coal?
Coal is a mineral mined from the ground. It's mostly carbon, but lower-purity grades can have a lot of other things in it. High grades of coal can be suitable for forging iron.

Charcoal is wood that has been heated with limited oxygen exposure to drive the water out of the carbohydrate molecules forming it, leaving a nearly pure carbon structure behind. It burns hotter than wood, and can be used for forging iron.

Just burning wood in air can leave mostly-carbon hot-burning coals behind, but they've already been burning for a while and so don't have as much energy left to sustain high temperatures. It has a hard time getting hot enough to forge iron. Some wood forges bake wood into charcoal using hot oxygen-depleted gases as it makes its way towards the center, but this is not the same thing.

>can you melt iron with a wood fire?
No. Dry wood usually burns at around 1100 degrees. Coals burn at around 2000. Iron melts at 2800. Note that above I mentioned forging rather than melting. 2000 degrees is hot enough to soften and forge weld iron and steel, but it's a long ways from melting it.

>what metal are the metal melting containers made of
Depends on the metal. Steel can be used for holding liquid aluminum and some other low-melting-point metals. Liquid iron is usually contained in refractory ceramics. Construction techniques vary depending on the scale and process involved.

If you want to get into backyard metal casting, there are guides for it. Keep in mind that casting iron is not something to do as a novice in the area.

Why do short breaker bars exist?
Halfords advanced set I've got came with a 3/8 breaker bar that's the same size as the ratchet. I thought it was so it's compact and fits in the case nicely and you're just supposed to stick a pipe on the end or wack with a hammer. However it has a sticker saying do not impact or use an extension bar.

Is this the intended use and they just put the sticker on so that you're not returning it under the lifetime guarantee all the time?

>> No.1523802

>>1523778
Breaker bars are cheaper and more robust than a similarly-sized ratchet. A stuck nut might be more than a ratchet should be tasked with, but a same--sized breaker bar can be abused a lot more without damage. Cheater bars on breaker bars are usually fine within reason. Hammers are less desirable, since they apply large shock loads that largely go into flexing the bar rather than turning the nut.

>the lifetime guarantee
That guarantee makes assumptions about loads, typically something like a strong guy with good leverage and the full length of the bar but not more. A cheater bar can exceed the design loads without breaking it, but that may subject it to metal fatigue and eventual failure. I suspect that the guarantee says something about using a cheater bar voiding it. They're cheap though. Do what you have to do if you just have a short bar, like you might have in a mobile toolkit.

>> No.1523803

A brush is used to set the stain in after it is applied with a rag. You want a wet rag to really have the stain soak into your grain.

There are benders that help but even using them requires some practice.
I have both styles of pic related in several sizes.
If the end of the tube is just a cut with no fittings I prefer the springs.
If the spring won't slide over the tube I use the formed tool.
Most of the time I don't need to make a tight bend and just form it between my hands.
>grip each side of where I want the bend and twist my wrists...

If a kink happens and isn't too severe, you may be able to take part of it out by using pliers to 'reform' the tube.

I'd try to find info about the saw or motor. this pic implies that your motor uses two lines of a three phase supply, which might be very wrong.

>> No.1525053

Will try to find about motor, but it doesnt have any info on it, maybe from some parts inside, that could have serial.
I'm thinking it could be 2 speed motor (maybe for something like 2 differend loads - IEC duty ciycles) because i saw in some catalogs table saws with 2 power values and like S2/S6 rating. This could be true because if u wire it black+blue+GND or brown+blue+GND, but will get someone check coil wiring inside. TY for pic.

good practice
when you do it 'for real' - don't forget the nut

and if you're going to bend it after flaring, put the nut close to the flare before bending.
if the nut is left past the bend it can sometimes be difficult to slide all the way to the flare.

Hey guys, I need to get an ethernet cable as well as some camera cables from the exterior (stucco) of the house into the interior. I've been trying to look for the best solution considering I don't have a hammer drill. I have an impact driver laying around but couldn't find a 5/8" bit (standard RJ45 is like 16mm or so) that could go with it. Would the cheapest option be to just rent a hammer drill or is there a solution for impact drivers?

>> No.1525825

>>1525820
Mang... what brand impact driver do you have? Home Depot still has all of their Xmas power tool sales going on and it might be worth getting a hammer drill. It was one of those things I never thought was a big deal until I moved into a house with concrete interior walls. You can try a regular drill or impact for hours, but then a basic compact hammer drill with a masonry bit will chomp through it in 10sec.

>>1525820
You'll need a hammer drill. Impacts are for delivering rotational impact to knock a nut open, a hammer delivers a thrusting impact, which helps a masonry bit chisel its way through the material. For what sounds like it's going to be a once off job getting a few holes done, any cheap piece of shit will get you over the line.

Also, don't be a faggot, get an RJ45 crimper and some jacks, cut the heads off and feed your cable without the plugs on. Will be much easier to feed it around without a rectangle on the end to get caught on every little edge it encounters and smaller holes will prevent vermin from using your cable run as a freeway through your house. I tend to wrap the end of the cable in electrical/masking tape to form a conical point before I start feeding it as well, again, one less hard edge for your shit to catch on as you feed.

>> No.1525863

>>1525820
Why you need 16mm hole?
Make smaller (idk diameter of wire) and re-terminate it.
Btw, for small hole you might not even need an impact drill. I made with cordless drill holes in concrete (2-3 cm thickness) without any problems, but it was definitely long

So far this is the most DIYish way. How would you ensure its centered, round and straight? I have a small vice ( cant secure the part well enough for machining ) and 600w hand drill. What could i do from there? I was thinking of using the seal grooves for centering (e.g. make 32mm disk) and then a sandpaper brush on drill.

Just really fine grit and polishing wheel afterwards. But from experiance sandpaper tends to eat away where it prefers (eg. Closer to edges, around the grease hole, near any survace grooves).

No, but they're relatively standardized within brands. Take it to a hardware store, there will be a section with a bunch of different ones. Odds are one of them will match.

May be a model stamped on the valve itself, which could help, but don't count on it.

We actually used that in the joists of the house I worked at as well, along with any joists that weren't thick enough.
So, there were 9" pockets next to the joists. We used (1.5"?) foam board, then foamed, then rockwool-ed the cavity, giving it an R-22.5 rating. One more round of Rockwool and it'd be more than what's in the attic. The only pic I have is of before we started.
