/diy/ - Do It Yourself

>>1238327
Power tools generally strike fear into the hearts of idiots everywhere. Bandsaws, not so much. I guess it is one of those irrational fears. Like being scared of babies or the color green or something.

Meanwhile, have a look at an old swing saw. No guard or anti-kickback protection at all.

those are safe things, assuming you use a pushstick.

for me, it was this, set up for steel cutting.

I have rather dodgy hand strength from tendonitis, and no tool has ever scared me just by turning it on before. I use 2.5kw belt grinders, pillar drills, bandsaws, anglegrinders, and a forge that's not far off being a flamethrower on start-up... but this is the only tool I've returned unused.

Generally not worried by spinning sharp things, very respectful of what they can do to limbs though.
High torque, spinning things though are fucking terrifying, abandon all hope ye who enter!

>>1238336
This is one of the first things I was warned about in OSHA training

>>1238327

I used to work at a place where I had a belt sander, it was 5hp and the belts were about 4ft long, I used 36 grit sandpaper belts to rip the covers off of HY-80, HY-100 and HY-130 steel test plates. The belts were held on by a pneumatic cylinder that even though the power was off, if you flicked the air cylinder, the belt would shoot off towards you. I got quite good at this it was kind of fun, it sped up changing the belt as it would be wound down by the time I repositioned the test plate. This white-knight do-gooder hired into our department and saw this, there was a bounty program where if you found a "safety" item they would reward you with $50. Well, they piped in this huge air shut off switch, so that it interlocked until the motor wound down.

For $50 this guy ruined my fun. Some people should never work around machinery. If you are terrified of power tools soon you will hurt yourself or others.

>>1238327
Bandsaws are predictable, not really that scary as its easy to operate it safely.

>>1238327
I think that's what one moron in shop class used to cut off the tip of a finger

lower the blade guide and don't run your fingers toward it, you'll be fine

>>1238332
People kill the fuck out of themselves with these. Take a leg off like it's nothing just because you slipped

Electric toothbrush is worse desu

>>1238336

What is this?

>>1238506
'PTO' power take off on a tractor, a large portion of the power of the engine in a spinning shaft you can hook various things to. like arms and legs and clothing.

Fairly much the best warning label ever

>>1238516

SECOND ONLY TO THIS

>>1238520
I blame single parent families, lack of responsible father figure in the home and not enough beatings when young

>>1238516
>he hasn't seen the workplace safety videos where this happens for real

Lathes. Table Saws. Angle Grinders when you think about what you're doing.


>>1238379
taking unnecessary risks like you were doing, and your carefree attitude means YOU shouldn't be around machinery.

Had a coworker who would do the same 'cheat' with millrolls winding down. Lost the tip of his finger in them.

Is you saving a minute in changing a belt and getting this stupid sense of bravado/pride over changing a fucking belt on a machine worth risking your health/safety? What if a new operator accidentally had hit that button.

>>1238327
For me it is the people juicer.

>>1238377

Know someone with a bionic leg from one of them. He was unconscious and almost died from bleeding out by the time anyone found him. And now he is a cyborg, some advances come with a price.

>>1238613
>he hasn't seen the Chinese video where this happens really for real

>>1238703
I was implying I had.

>>1238682
i wonder how long it takes to setup that crank in the 4 jaw.

think the centers are +/- a thou?

>>1238732
The centers might be, but that part isn't.

>>1238327
>tfw want to make your own bandsaw,
>tfw too afraid of having violently spinning blades of death near you.
>tfw afraid of freak accident due to something you forgot when making your own.

Table Saw. Not that it is inherently dangerous, but because it is used so often that it become just do instead of what I need to do.

>>1238815
For normal wood working? Radial arm saw or jointer. Jointers scare me because you are literally pushing your hands with force towards a heavy, spinning cutter. Radial arm saw for obvious reasons, but now a days, a table saw and compound sliding miter do everything a radial arm saw could.

For metal? Lathe.

Metal Chop Saw with a Carbide blade. Had a fellow classmate in welding that slammed down the saw and teeth flew off and lodged in me. What is the reason this tool even exist? Just use an abrasive wheel or a bandsaw.

>>1238821
abrasive wheels are also made out of silicon carbide and are just as dangerous. metal cutting bandsaws with deep throats are expensive as fuck

cold cut diamond saws are superior chop saws anyway.

>>1238821
>What is the reason this tool even exist?

Because it's objectively superior to an abrasive cutoff, in every way except initial cost.

You ever seen a damaged abrasive disc just outright disintegrate? Because that'll do a lot more damage than a few grains of loose carbide. Don't be a little bitch.

Honestly, no tool scares me anymore. I just always have a sort of background, subconscious respect for the fact that my hands/arms/face/dick/whatever is just inches from sharp/heavy chunks of metal going fast enough to wreck my shit.


Exception: Butcher's bandsaws. A normal bandsaw is fine; even if you managed to catch it bad, unless you've got a really aggressive blade on there (like a 3TPI resawing blade), you're probably going to walk away with a nasty gash and a good scare.

But a meat-cutting blade on a saw that may well not even _have_ a guard? You're going to lose a hand and you won't even feel it until it's too late. Those videos of people working a little TOO fast in the meat department on the saw pucker my butthole like nothing else.

>>1238874
bandsaws are far more versatile than a chop saw

>>1238888
this guy gets it. just set and forget.

No one did the meme

>>1238938
memes are so 2016

*screams internally*

>>1238819
ive never heard of anyone injuring themselves with a jointer, that would be pretty special. its not like that piece of timber is going to magically disappear, and even then anyone with half a brain is using big push blocks

>>1238952
Is that a press brake/punch/shear?
The sound is the scary part.

>>1238960
Yeah.
>The sound is the scary part.
m8
Try punching with improperly mounted dies and get back to us.
Actually don't.

>>1238964
The only scary part of punching with improperly mounted dies, is when you realize you just fucked up a very, very expensive piece of equipment.

>>1238966
Tell that to my former coworker who had a piece of die imbedded so deep into his arm the doctors didn't even bother trying to pull it out.

>>1238967
That sucks. Was the punch press ok?

>>1238969
Yeah I think it only broke the benis die.

Worked in a warehouse for 2 years and then as a carpenter for 12. The most dangerous thing ive come across is pic related.

>>1238952
Thats a wierd looking thicknesser.

>>1238874
Just get a portable bandsaw with a stand and table.

>>1239024
this.

For me it's the bench grinder but only because I have been bit.

>>1239077
How much of a fucking potatoe do you have to be to get your forearm in a benchgrinder?

>>1239079
I was young and dumb, working bolts on the wire wheel with my forearm in front of the grinding stone. Wire grabbed the bolt and pulled me in, stalled the 1/2 hp grinder because my arm was jammed between the stone and the grinding rest.
Got fucking lucky, it stopped ~2mm from the artery and I could see it clear as day before the graft covered it up.

>>1238819
What the fuck is wrong with a radial arm saw? Just keep your hand clear. Let go and it'll spring back.

>>1238819
>Jointer
>Radial Arm Saw
How irresponsible are you?

>>1239088
He is probably the reason all household fans now come with grills.

>>1238327

The most dangerous thing in the shop is a loss of focus. It doesn't matter which tool it is.

That said, even if you were trying to cut off parts of yourself on purpose, it wouldn't be that easy with a band saw.

>>1239106
Woodworking fag here, ive touched the blade a few times. You instinctively pull away long before you get even a minor boo boo.

>>1238698
>>1238327
Do you guys like mcchickens?

>>1239129
Anyone who's been here for more then 3 weeks already knows every meme for every board. Youre not special for getting the reference.

Wheel grinder and belt sander.

Wheel grinder I had to use was fucking loud as shit and has general feels like it wants to just kill you. Also if burning yourself when you don't realize the piece of metal you were working on

The belt sander is pure evil. Depending in it's use and abuse, a while can developed at anytime and fuck you hard. I've had a smaller piece I rounding the edge with when a hole formed and took the piece and my hand suddenly down into the base plate at a speed fast enough to split the skin on my thumb. Then there was the time the adjacent sand wheel grinded part of my nail away when and I only noticed after I smelled nail.

>>1239137
>every meme for every board
hit me with those /p/ memes senpai

>>1239225
Dont take my words seriously you dick!!

Scrollsaw, im incompetent amd have snapped so many blades and had them fly past me that i stopped using it and just use hand tools for that

>>1238327
this is my archenemy, fucker nearly took off a finger or 2. never wear a fluorescent jacket while using one of these

>>1239328
bitch please

>>1239361
Is that fixed angle grinder? Why don't you just buy circular saw ffs

>>1238327
An angle grinder with it's protection removed by my father, I don't know where it is and I don't have cash for a new one.

>>1238330
>Power tools generally strike fear into the hearts of idiots everywhere. Bandsaws, not so much. I guess it is one of those irrational fears. Like being scared of babies or the color green or something.

Accurate. Fear comes from a lack of knowledge, experience and competance. If you're fearful of power tools it's either because it's unsafe and shouldn't be used anyway or you're unsafe and shoudn't be using it without supervision who knows what they're doing.

I've cut the end of my thumb open with a bandsaw and I don't blame the bandsaw, I blame my own stupidity but I'm no longer fearful of it because I learned the hard way.

>>1239328
they're worthless anyway. flap disks or carbide grinding wheels are far superior for cleaning up steel

>>1238703
The thing i never got about those videos is why the fuck would you have your hands/feet there to begin with. If you're that much a retard to be hugging the work piece spinning at 2k rpm you deserve to be turned into rotini pasta.

The scariest tool in the shop is the clapped out milling machine with 200 thou backlash, because no matter what the fuck you do you will always end up with some sketchy set up right at face level and you never know if that 5 thou climb mill is going to look great or give you summerteeth.

Guess this would probably help explain why every old toolmaker i know is incredibly smart but borders on insane/paranoid.

>>1239462
Can confirm. Flap discs masterrace.

>>1238506
We always called it the bush eater lol
It's a 6 foot+ mower deck that is directly driven off the drive shaft of the tractor. The deck moves, the back of the tractor is a dangerous by itself, the 6" shaft is rotating with virtually unlimited torque, the blades are sharp as fuck, the whole thing is a goddamn death trap but there is nothing it can't mow through.

>>1239328
Never ever ever ever fucking forget your safety glasses Jesus Christ. Most pain I've ever felt, a wire went through my eyelid and right into my iris.

>>1239403
Its like you dont even want injury payout.

>>1238327
>the most terrifying power tool
I'm gonna go with lathe.

*Ruptures your ear drums*

>>1238698
What.. happen.. here

>>1238327
large circular saws are far more destructive because of all the kinetic energy the spinning blade has...
Bandsaws just do clean cuts, a circ saw will fling things at you if do something dumb.

>>1239743
>loose long sleeves
>lathe running
>sleeve get cought on work or chuck
>lathes are a lot stronger then humans, resistance is futile
>literally squeezed out like toothpaste

>>1239750
Anyone who's used a circ saw for more then an hour shouodnt have a problem with torque. Whats really dangerous is when people start fucking around with the gaurd, same with chainsaws anything that you can get tired with and swing past your leg is dangerous as all fuck.

>>1239751
My workshop teacher had that happen with a tablesaw. Giant scar down his hand and wrist (where you'd make a karate chop).

>>1239750
>>1239752

carpenters in our framing crew will hold a board in one hand and hold the circular saw in the other hand to make a cut, without using a saw horse or anything to steady the board. Not just 2x4s either, anything they can hold in one hand is fair game, plywood, whatever.

Looks scarey as hell to me, but they seem to think it's ok.

Had a bad experience with a table saw once, didn't get hurt but almost had an 8/4 oak grill. They still make me uneasy.

Fucking angle grinders, never had a bad experience personally but last year our plant had 11 recordables, 7 were related to angle grinders. One guy had to take an ambulance to an ER because they couldn't do anything for him on site, one guy got air lifted because a wire brush caught his shirt(after he let off the switch) and dug into an artery. Other injuries included a borken jaw, broken wrist, and several gashes.

>>1239754
Not normally too bad, the danger comes when you do this often and your arm gets tired.

>>1239751
Why so thick though? Was it a fat man?

Was this on an ordinary lathe that reach up to your waist? It seems the more incompetent a person is the more interested they are in telling others about horror stories.

>>1238327
I cant say any tool makes me nervous, but the one that makes me uncomfortable just so happens to be my favorite tool and my no.1 go to.. the angle grinder. I just always(usually) make sure that Im out of the shatter zone and I know Ill be fine

Lathe probably, baaically what
>>1238336
Said

A cut can heal, but a twist from a multiplied engine is probably going to cost you your life

>>1238327
Only bandsaw that gives me the willies is the one the guy from TipsFromAShipwright on youtube uses. It is a behemoth sized saw, which is fine, and not scary because of that. The scary but us that it has this wagon wheel thing on the front that he has to kick to get the motor started. That wheel continues to spin at high speed while the saw is running. No safety cover on it and it's very close to where you would be standing when using the saw.

>>1240411
Circular saws in angle grinders have a great way of ending up in people too. There's some fantastic injuries where they usually grab someone's shirt and then embed themselves into the operator's guts balls deep.
There was also a couple of gronks once that chucked a 12" wheel on a 6" grinder while cutting masonry, that came apart like a bad lie and sure enough the guy wearing the safety squints for PPE ended up with it right in his dome. While its not funny that he died, it really did look like something from a cartoon sticking out of the front of his head.

>>1240424
i always see people using cuttoffs on youtube without any ppe or a guard. not even safety glasses. Grinders scare the fuck out of me. My ppe includes a face shield, welding gloves, eropro, and a fucking carhart jacket.

i've got a diamond metal cutoff wheel that's always catching on the lip of a cut. every time it jerks itself backwards and up in the direction of the operators neck.

>>1239361
*screams externally*

>>1238330
Poorfag with no power tools here, whats "anti-kickback protection"?

>>1240493
Its a sensor that detects if the saw, grinding wheel or other wizzy device gets in a bind with the work piece and theoretically shuts it down in time to stop the operator being murdered by splinters of wood, steel, rock and if they're really unlucky, their meat clogging up the works.

Course, on something with a big enough mass, that doesn't matter so much because its going to keep spinning regardless of no power going to it.

>>1238327
I mean have you seen the videos of these.

>>1239022
This but the auto retracting ones.

>>1238336
yep, NEVER go near a running PTO. your shirt or something gets caught in it you're pretty much fucked. there's not a single piece of your body strong enough to stop a PTO, it will literally rip limbs right off your body no fucks given

>>1238613
damn my father kind of just started a small farm for his retirement. I can watch liveleak videos all day long no problem but if i would ever find him wound up on that shit i would probably just end myself too.

>>1239413
My father has one of those too plus the button broke so it's always on when you put the plug in.

>>1239546
Damn if wire wheels aren't great for removing rust though, but when the large diameter ones bite or catch they're a little scary.
It seems like if they got caught in your clothes they could do a bit of damage, especially on a 9 inch grinder or such.

Oh, easily belt sanders. You can get
fingers and shit lopped off real quick if you aren't careful

>>1239582
Fucking this, having to hold weatherboard while somebody is nailing it, while your head is close to the board. Ive shot quiter 30-06s

>>1240424
>diameter too large
>no problem, just remove the shield!
Deserved

I refuse to work with anything high pressure related.

Austal, a Australian ship contractor building half the Littoral Combat Ships (the ones with all the problems with the hulls corroding away) for the Navy in a partnership with General Dynamics, recently got in trouble for using those.

https://www.revealnews.org/article/this-tool-cuts-fingers-and-gashes-faces-but-shipbuilder-still-uses-it/

>For years, managers at Austal USA’s shipyard in Mobile privately fretted about the danger of a tool they’d modified from its intended use. In an email three years earlier, Chris Blankenfeld, the company’s top safety manager, called the machine a “Widow Maker.”

>“These millers are quite literally an accident waiting to happen,” he wrote to company officials, referring to the tool by its shipyard nickname.

>He was right. At least 53 Austal workers have been injured by the tool, losing fingers and suffering deep gashes on their faces, necks and arms, according to injury logs from January 2011 to March 2015 obtained by Reveal from The Center for Investigative Reporting.

>Austal managers continue to put the modified grinder in workers’ hands, employees say. Roughly one-quarter of the shipyard’s more than 4,000 workers still might be using the tool, they say.

This guy can throw a mean right hook.

FALCON PUNCH

>>1238336
Growing up on the farm, my old man was very graphic in his warning of what would happen if I ever got anywhere near the PTO shaft. And a good point he made was "you see those hundreds of metal teeth on that swather that could tear you to shreds? They are ALL POWERED BY THIS ONE LITTLE TUBE"

You wouldn't expect something so unassuming to be able to murder the fuck out of you so easily, that's the gnarly part

>>1240493
most grinders have it these days. basically if it binds up at all a brake activates. it's mostly to prevent kick back(can really fuck you up) but can also save your ass if it happens to be your flesh and bone binding it up

>>1241117
yep, whenever someone new comes around the first thing any decent farmer will tell you is to stay the fuck away from the PTO. it really is amazing the number of people that will still go near them tho.

>>1240514
lol. In my school we learn how to use them at 15 yo

>>1239462
Nah, cleaning slag from a weld is so much easier and non destructive with a wire wheel.

>>1241140
>fluorescent jacket
>SMAW

pictureofaharddrivecontainingfoldsofanimegirlswithconfusedlooksontheirfaceandswastikas.jpg

>>1241143
Not that guy btw

>>1238332
I've used the one my machinistbro bought (before it got stolen) and they work just fine but I prefer my Metabo angle grinder with cutting disks because it's equally fast cutting and I can use the edge of the abrasive cutting disk for deburring.

If I needed to cut aluminum stock or plate I'd buy an Evolution.

Fire? Nigga please. Run an arc gouger or oxygen lance sometime. They are great fun too.

PTOs OTOH will fuck you up along with many parts of farm machinery. Shut the fucking engine down every time all the time when working on them and chew ass if anyone else takes a risk near them.

Lathes can kill you just as easily.

>>1241125
any decent farmer will have shields over the pto shaft and joints, at that point you have to be literally braindead and stick something in there for it to grab you

>>1238327
It's always the least assuming tools that are the most lethal, any shop goer can tell you that.

>>1239551
They weren't talking about the bushhog, they were talking about the PTO shaft in general.

>>1239582
FUCKIN BRAINDEAD PAT PASLODE MONKEYS NOISING UP MY JOBSITE REEEEEEEEEEE!!!!!!!!

>>1241867
Indeed, 99.3% of all deaths are caused by the most unassuming tool yet.

>>1241880
one of my boys may have permanently fucked his finger with one of these

or rather someone clipped him with one but still

boxcutters are shockingly sharp for something meant to savagely tear apart product packaging for recycling, theyre like fucking medical scalpels ffs

>>1241880
Almost stabbed myself in the leg, and thought I was cutting safe and everything.

>>1240452
I saw king of random use one and he "put on gloves for protection"

>>1241880
They can bring down planes

>>1241894
>or rather someone clipped him with one but still

always cut towards your friend

Not as flashy as some of the other stuff here, but so many broken hands. Especially the older low rpm ones without both handles.

>>1241132
I also had unsupervised access to a metal lathe in jr.high shop class. Granted this was 20 years ago and the shop teacher in question was of questionable sobriety (during class).

Make no mistake though, anon, those things can bite and when they get ahold of you they do not let go until something breaks or gets torn to shreds, up to and including your whole body.

I own a lot of woodworking tools.

2 Table saws, 2 lathes, 2 grinders, any number of drill bits up to 3", drill press, cheap band saw, chainsaw, compound miter saw.

Also own a Makita 12 9/32” beam planer and 16 5/16" circular saw meant for timber framing. THESE ARE SERIOUS TOOLS AND ARE DANGEROUS IN THE WRONG HANDS.

The chainsaw is dangerous for me because Ive used one for years but dont get as much practice as Id like on it.

>>1239361
Total shitshow of a tool to replace others that are more specialized but safer to use

>>1242247
honestly the only danger in a chainsaw is throwing your back out from yanking on the pullstart 300 times until it starts

>>1240452
don't wear gloves next to spinny grabby things

>>1242252
you must have a Stihl

>>1241867
Has anyone ever tried attaching a dildo to one of these?

this gives me anxiety

>>1242121
This, also impact drivers in the early days. Not to bad under regular use but every now and then the hammer would jump under torque and your hand would go 100 degrees in a fraction of a second.

Behold, walking lathe

>Go to use a shot of black on my PTO
>Mechanism backfires
>Triple shot of black straight into me urethra

Now I'm gay, dont make the same mistake

>>1242994
Yes, but you're a professional gay.

Table saws scare me just because I've had a kickback on it from being dumb/newfag to woods and I watched someone cut their finger off. I know they can be used safely but I avoid using them.

>>1242114
never underestimate how retarded military people are

>>1239754
That or using your foot as a pivot to hold up the end of the board you're cutting. That was common where I worked

>>1243277
I just did this last night.

>>1243582
i always cringe so hard when i see people holding the work they're cutting with the hand on the underside on youtube. I guess they don't really realise they wouldn't even feel cutting their hands of until it's much too late.

>>1238952
how much better are those than an arbor press?

>>1239476
if you're using a mill with .200" backlash you're an idiot that can't replace the leadscrew

>>1242261
and don't touch spinning things at all, that's what chip brushes are for

>>1240514
to be honest, a mini lathe like that is probably about a half horse motor, it will certainly fuck you up, but it will stall the motor eventually.

taking heavy cuts on steel with one of those will stall the motor for instance

>>1244610
dont they serve completely different functions?

>>1239582
I met a guy in therapy who actidentally killed someone with one of these.

Hello dislocated shoulders and fucked up rotator cuffs.

This was the no. 1 cause of workplace injury at my job.

>>1238327
>the most terrifying power tool
that would be the manual lathe.

If you treat a bandsaw like a tablesaw, it is perfectly safe.

>cutting 1/4" lexan with pic related
>using fence and push stick
>as soon as cut is complete, scrap is launched 20 feet into the side of a trash can

>>1245037
Look into adding a riving knife to your saw. It helps protect against that very occurrence. Either that or build a miter sled and ditch the fence. That way the cutoff can't get stuck between the blade and the fence and get shot out of your saw.

>>1238327
Don't ever fuck with split rims

>>1238330

It's perfectly healthy to have respect for power tools, guns, motor vehicles etc. and be wary of them (irrational, panicky fear is something different).
What you really need to worry about is the moment you STOP worrying. Because from that moment on it's only a question of time before someone gets hurt.

>>1245157
split rims aren't that bad, especially the ones with lock-rings. never had one blow on me out of a thousand changed.

now widomaker rims are another thing. Those have a like a 50/50 chance to blow even if you are skilled. too much lube on the lip? they blow. lip isn't perfectly even? they blow.

fuck that.

>>1245175
>split rims aren't that bad
rong

>>1245037
>>1245073
just push the shit away from the blade when the cut is done, all that safety shit gets in the way, the only thing you need is a fence and maybe a featherboard

>>1239754
Do this, all the time. Never once felt unsafe, and I realize and respect how dangerous skil saws are.

>>1242031
or a fistful of dollars (or 30 years in a subsidized housing project)

>>1238327

Only normies are terrified of saws, which usually take fingers (hands at worst) and have shit tons of retard-proofing features nowadays, when it's the lathe that will reward stupid mistakes by wringing you like a wet rag in a fraction of a second, and then it's goodbye to an open casket funeral for you.

>You need to have respect

>>1245037
are you sure, you know wtf you are doing?

>>1245415
the thing is though that most people will probably use a powersaw in their lifetime whereas very few people even know what a lathe is

>>1242295
Total KEK. I hate my wifes Stihl weedeater cause its fucking pictograms for start and choke are useless.

20-30 pulls to start it is no unusual.

My Huskvarna chainsaw usually starts on 2-3 pulls

>>1245415

Yeah, but how many normies have ever even been around a lathe that could do that? About the only ones who would have one would be machinists, who aren't exactly a large portion of the population.

But just about everyone even passingly into anything remotely /diy/ has SOME kind of saw; chainsaw, reciprocating saw, circular saw, table saw, miter saw, etc. Plus, these are usually all loud and "aggressive", visually speaking.

Lathes, by requirements of their functionality, have very precise, deliberate motions and appearances, which completely belie the fact that there might be 10HP and a couple hundred ft/lb at the spindle. Makes perfect sense that those who aren't familiar with them aren't aware that they could completely wreck your shit if you make even a seemingly small misstep.

Here you go fellas. I hate how this is my only fucking grinder.

>I hate how this is my only fucking grinder.
Why? That is a B&D from their prime. It is probably one of the best American made grinders to ever roll off an assembly line. As long as you have the man hands to wrangle a 7/9 inch grinder then it is the best. It is probably about 40-50 years old and still kicking ass. I could get more accurate with the age with a full picture of the dataplate if you are interested.

Please dont

I mean, I'm really glad I own it, just don't like having to zipcut on a grinder with no guard.

Non-auto anon here. I thought widow maker rims were split rims. What's the difference. Also please see attached athletes foot.

just imagine the mega scale version of a lathe or PTO, the drive shaft on a large cargo ship. it looks so serene as the perfectly smooth shaft silently spins around 100rpm, but then you realize its close to 300ft long, has a 30ft wide 20 ton propeller on one end and a 74,000hp diesel engine the size of a building on the other.

Yes. It was back when I was a machine builder. We'd cut large sections of it for guarding on all the machinery we produced. 1/4 inch Lexan can flex quite a bit when you're ripping 4-5 foot sections. Everyone hated that fucking table saw. Eventually the shop invested in a panel saw.

>no guarding

Never liked these, co-workers friend got stuck in one just a 3 months ago too

You dont seem to understand the meaning of cutbacks. Plus its probably to expensive or time consuming to have an apprentice to turn/cut an acme thread over the course of an hour.

That's why you need a wheel on an arbor press, not a lever.

6 foot or so lengths are $60 on msc

if you need a new nut that would require grinding a toolbit (or overpaying for acme threading inserts) and doing some internal threading, still shouldn't take too long.

but I concede the point, it's not something a major business would fuck with--but in a small shop you bet your ass repairing the machines you have would be important.

>>1245831
also will want an acme thread gauge as a reference for grinding, they're like $30

Been around machinery my whole life...knew a guy working on a PTO that was engaged (old wrecker) he had long hair....well you can guess the rest. He wears a wig now forever. He's lucky it only scalped him. I had the most repect for the old 3 piece split rim wheels they called ( The Widow Makers) you fuck up with one of them and the party's over. Seen people get messed up because they were cocky and didnt listen.

Here is a square thread nut repair. It had been repaired before too (previous repair forgot to drill the oil hole, it failed).

The grind on the toolbit is sloppy but it is square for the depth it needs to be. The edge at the end has some dirt on one side so it looks slanted.

What exactly is that? A wood lathe?

I have no feeling in the top half if my left thumb because of these
