Any tool is going to be dangerous if you a) don't operate it safely and b) keep it in good repair

That being said my husband did something bad to the bandsaw and banned me from ordering the parts for fixing it (it's a ryobi and they aren't great quality but the upper guides and the tension adjustment shouldn't be broken), so I'm just going to buy a new bandsaw but he happily uses it and it's clearly not safe.

>>689684
Knives.
From using dull ones to stupid using sharp ones.|
I am far from retarded, but the other day I was using a serrated knife to slice bread.

And...forgot my hand did not meet the standards for a cut-proof surface.
No stitches needed but a painful and irritating 3/16" of an inch across the palm of my left hand is a bitch.

Bad thing is it ain't the first time I forgot my hand is not a cutting board.

>>689712
What did he do to the bandsaw? And what do you do with a bandsaw? And can I marry you?

>>689703

workshop safety is a really huge concern, especially around the house

A kitchen mandolin

Router. I've become pretty adept at routing by hand over the years...but the machine still fills me with dread. Feeling the jerk of torque as you hit the switch, waiting for it to spin down, the way it bites into wood. I always feel like I'm a slipped grip or lack of focus away from an unwanted trepanning.

>>689684
Rubbish.

You will never injure yourself, unintentionally, in any kind of irreparable way with a knife. Professional chefs work with them twelve hours a day, and injury rates are on the order of an ouchie, per month, per brigade.

The amount of force, and the areas of the body it's near to, means that a moment's inattention with a normal knife, used normally, can never do you more than a boo-boo.

Compare:
- permanent cornea damage from ejecta (dremels, saws, drills)
- death by electrocution, chiefly by using the device to cut its own electrical cord (saws, grinders, garden tools)
- crippling damage to limbs, digits through one quick trauma (saws, drills, grinders, nailguns, jacks, even hand tools if something lets go or slips suddenly)
- dehabilitating lung conditions from chemicals and dusts (grinders, sanders, saws)

What's the common theme with the above, though? They can be ameliorated or avoided through proper PPE. RCDs will protect you from ground faults. Gloves will protect you from edges. Masks will keep dust out.

If you do nothing else, listen to Norm and buy a pair of safety glasses. You can get them in dollar stores. They could save your sight.

>>689782
you are an idiot.
slip with a knife while slicing and end up with a permanently numb and unusable finger.
Fuck up and slice a 1/2" of the meat from the palm of your hand.
Chop a finger or two off.

Go get your mom to give you another enema and suck your dad's cock, faggot.

>>689780

At least that one's not as bad as what the YTMND guy did.

>>689772
If I had to guess I would say trying to cut something made from resin and forcing it through while turning it sharply but that doesn't explain how he broke the blade tension at the same time.

I usually use it to cut turning and carving blanks and to (gently) rip smaller pieces of wood into shaft blanks for drop spindles.

The large band saw that we had had the mill. That thing was the most frightening

>>689782
>Dremel
If only because they advertise these rotary tools to amateurs. Fractured cutting discs terrify me, and I imagine people that are ignorant (not using the word disparagingly, just people are uninformed) of the danger and won't give the tool the respect (fear) it demands

>>689785
You are an idiot if you allow a knife into a situation where it can do that.

It's only your hand that's doing the pushing. It only pushes as long as you tell it to. It can't cut when you stop. It has no power or volition of its own, it's just a bit of metal.

>>689817
Hell, use the thing in the wrong hand, and the debris spray goes straight in your face.

Corneas don't unscar.

>>689785
These things can never happen to you if you use a knife right, because there's never any of you between the blade and the board.

How d'you know your right hand is away from the edge? Because it's holding the handle.

How d'you know your left hand is away from the edge? Because your nails are touching the blade. If something's touching the blade, it can't be under the edge.

You might as well be saying that a daffodil is the most dangerous thing in the world, because you can stuff one down your trachea, and then you die.

>>689796

A mill saw isn't really a household tool, friend

>>689842

You're right, the knife is no longer deadly in the 21st century :^)

Man is the most dangerous tool

>>689684
Muh dick

>>689742
are you shapenning the profile right?
the edge of a utility knife should be steeper/sharper at the tip and a more blunted heavier angle at the hilt. this way you chop with the hilt and slice starting with the tip.

>>689684
Arc welder that I made out of microwave oven transformers.

It's fucking terrifying.

You guys are looking at it all wrong.

Most cleaning chemicals area deadly if ingested, and can cause blindness if it gets in your eyes.

Household chemicals are definitely the most dangerous tool.

I'd say a lathe, there is no surviving an accident with it.

lefty here: all power tools are out to kill me.

that said, I feel pretty safe with a chainsaw over a skill saw.

>>689702
this.
also .. depends on what house (I have a *lot* of dangerous shit but personally the one that makes me nervous is the tanks of acetylene).

>>689684
the most dangerous tool, is you

>>689915

Pics for reasons

>>689996
>lefty here: all power tools are out to kill me.
Lefty here: drill presses, radial arm saws and lathes are by default set up for us south paws, the only tool I've ever had issue with is a circular saw and that's easy enough to manage by flipping it around. Chainsaws come left handed or right handed (and you can get a nice left handed one used on the cheap because right handed people are terrified of them.)

We're pretty safe in the shop, it's the rest of the world that's trying to kill us.

>>690035
>>689996

Lefties are devil spawn and you deserve whatever power tool induced fate awaits you

>>689742
You can buy steel mesh gloves for kitchen use. I have not used one personally but it's worth a shot. If I ever had to go back to slicing meat and cheese in a deli I would definitely get one-- I can't count how many times I've seen people get into a rhythm with cold hands and just take off a thin slice or two of hand or finger-- not massive damage just a lot of blood.

>>689969
I don't feel lathes are any more dangerous than any other tool. At a metal lathe I'm standing at the control side (think etch-a-sketch) and not in front of the metal at all.

On a wood lathe the spin of the piece usually forces any larger debris towards the tool rest and the smaller stuff at your face, so long as you're wearing eye protection and a mask (because wood dust will fuck your nose, mouth and lungs) you're okay.

So really the remaining dangers are from absolute carelessness or intentional stupidity. Fingers between piece and tool rest, attacking the piece with the wrong tool, putting your face directly on a piece, loose clothes, etc. but if you chuck things up properly and show a minimal amount of regard for your safety you'll never get injured unless someone actually pushes you face first into it while it's running.

>>690037
Yeah, but we have talented freak hands that can magically make whatever and have it come out perfect.

>>690047
Well then, no tool is that dangerous in a way that it might hurt you at any time regardless of what you do. All tools have a proper way to use them without getting hurt. This thread seemed to be more about what's the most dangerous when an accident happens.

>>690053
>This thread seemed to be more about what's the most dangerous when an accident happens.
By number of injuries or severity of injuries? By number of injuries I would go with rotary tools like dremels because even when operated correctly can really fuck someone up because of manufacturing failure and they are marketed towards people who have no clue what they are doing.

By severity of injuries I would guess bandsaws and only due to operator error/inattention

>>689684
Vehicles

Probably some chemicals. The biggest power tool I have is just a drill, but if the shelf in my darkroom fell over and the potassium ferricyanide spilled into some hydrochloric or sulfuric acid, it would release hydrogen cyanide gas.

But I guess that's pretty unlikely since they're kept in different cabinets because I do not want to die.

>>690035
>flipping it around.

never have I attempted to flip a skill saw purely for the fact that my grip is setup in a way that if I get kickback, I wouldn't have sufficient grip to control through it. chainsaws are setup for right handed use, but the area of usable blade is almost a complete 360°, so you can use the backside of the blade left handed, and get the same control. better still, you can alternate between hands as fatigue demands, and keep production up. if all power tools were as efficient and as thought out as chainsaws, I'd never have to worry about my tools.

don't have a lifestyle out job that I find myself using table tools like lathes, articulating saws, table saws, drill press, etc. those all seem pretty safe with maybe the exception of a grinder wheel.

This.

I've never seen something as lethal as this.

If you ever make the mistake to underestimate its power, you're going to be severely hurt.

Chainsaw is way up there. With proper protection and respect it is increadibly usefull. But it is unbelievably unforgiving if you fuck up at all. You dont nick with a chainsaw, if you nick something, its fucked. Nick your leg? Hospital. Nick you arm? Hospital. Nick your neck, head or chest? Morgue. I can fuck up pretty bad with a table saw or drill and still only need stitches.
Same fuck up with a chainsaw? I'm on dissabilty after that, or dead.

A unknown variable would be my plasma cutter. What that thing would do to me if it ever hit open skin......shit. Sweating just thinking about it.

a car

>>690113
Grinders aren't bad, although I'm convinced some of the shields on the old ones are purely decorative.
>for the fact that my grip is setup in a way that if I get kickback
You can make or buy a track for your circular saw if that makes you feel more secure. I've just gotten used to using them right handed but a few times when I felt I needed more coordinated control I just turn it around and cut tail to tip.

ER doctor here, stanley knives (retractable blades) and screw drivers are top of the list. 9 inch grinders are big problems too, but mostly for manlets or the under 25s.Chemicals, weed killer, bleach and caustic soda are the main ones, usually splashed into eyes.

>>690126
>Chainsaw is way up there
You watch too many movies. Chainsaws jam when they hit flesh. You'll do some damage but you can't kill a fucking zombie with it unless you use it as a freakin' bludgeon

Agreed. I pity the burglar who breaks in while you're armed with that

>>690126
Plasma cutter would have to have a catastrophic accident, like an explosion, to be truly dangerous. Sure it will cut through flesh but the beam is narrow enough to keep collateral damage low v

>>690190

There's plenty online already. Beheadings and pig bisection. Shit goes through just fine.

I've cut through tons of cactus, rotted wood and hard woods within 10 min of each other. Decent saws don't "jam" unless you run it without oil.
>Only dumbass thing was cutting rusted barbwire. 80s % of the time just shears it instantly, but sometimes will catch and pull you or the saw.

>>689684
Sawzall are the most dangerous thing ever according to the last few worksites I visited. What keeps happening is people want to cut out some drywall and end up going through pipes, wires, structural support, etc. Using one for ten minutes requires a day of paperwork.

>>690243
>Beheadings and pig bisection.
I don't have a dog in this race but I want to see chainsaw vs. roast, do it bro

>>690116
I've given myself some nasty cuts with my Leatherman saw, but it really, really isn't as bad as you make it sound.

>>690245
it'd be kinda moot since a roast wouldnt be a proper simulation, but I also wanna see it happen

cattle are a lot tougher than a given section of a person, bones are the parts you need to worry about sawing through, any part that could get reasonably in an accident with a chainsaw are soft enough it'd rip and cut the flesh without much problem, whether its a beer belly or a forearm

8" Angle Grinder into a vertical surface. Utterly fucking terrifying.

>>689703
Your /g/ level shit posting has no power here.

Angle grinders scare me - particularly ones that don't have guards. Worst injuries I've had have been from hand tools though (screwdriver stabbing, spanners slipping off, general swiss army knife cuts)

>>689915
Mike?

>>689817
I'm a noob using a Dremel and it TERRIFIES me. I wouldn't use it at all it it wasn't so damn useful. The idea of a brittle disk spinning at 35,000 rpm with no safety guards, no mount and a lock-on trigger.

High impact face shield, safety Goggles, N95 filter mask, ear plugs and gloves, every time.

I work in a hospital mind you so PPE is like a religion to me.

>>690305
just make sure you get the 4000 model/higher wattage. and look for the fibreglass reinforced disks for the ez-lok system. cheap disks break a lot more. but fuck me, those official disks are expensive.

>>690236
It will still slice and cauterise you'll have a very narrow 3rd degree burn which could fuck up underlying structures depending on where the cut is.

Definitely hospital material, but not very lethal.

>>690047
>>689969
I was thinking the same thing, lathe, for obvious reasons like stated, but again, everything is dangerous when you dont know what your ect.
but the work piece is still spinning so damn fast, its not like i stand in front of my piece but still.

Id go with bench grinder. but because of people not knowing how to properly use it.
like not grinding on the side of the wheel

Statistically speaking (at least here in NZ) the most dangerous tool around the house is a goddam ladder. Well that's the cause of the most acc claims

>>690332
bench grinder with an open calico buffing wheel is pretty bad if you go below 9 o'clock. worst tool I've seen is a 5" grinder with tungsten carbide aluminium cut off wheels pic related, even with 2 hands and properly fixed work these things always go for the face when they catch. only tool that makes my heart race every time i'm using it

>>690355
in saying that on an air driven grinder they're much safer

Extension ladder. Nominated as it is the only tool that has ever caused an injury to myself.

At work, the most dangerous thing would be the angle grinders. Not a single one has guards on them nor do they have handles. I've tried putting the guards back on but no, "they get in the way" they say. And the handles are broken off at the bolt so you can't easily put a new handle on. Osha has already gotten our ass on that before. The workers run the place, not the boss. I'm trying to do my best to make us so Osha won't rape our ass as much next time they come. It's not easy.

At home, though I don't do much, I would say it's the table saw. I hate using that thing worth a passion. Fingers are as far away from the blade as possible but I just know that the blade is going to hit me.

Or a reciprocating saw. I just do not trust how the saw blade is held in place. I feel it's going to fly out any second.

>>690370
I have had the blade fly out of a Reciprocating saw, it was a very cheap saw. Fortunately it flew out forward as the clamp failed and the blade didn't shatter.

Wear your PPE guys.

>>690305
>I work in a hospital mind you so PPE is like a religion to me.
Since you have a job, I highly recommend that you start replacing the Dremel with other tools-- just maybe one or two tools at a time as space and finances allow. As time goes on I've found less and less use for my Dremel tool because I have the job specific tools to handle specific jobs. I actually kind of cringe when I think about using it now.

>>689684
If you think its not a tool, youre a fucking moron

>>690190

Stop using china freight chainsaws. My Echo would go through you like butter. A chainsaw would ricochet off of cement or stone, definitely metal.

>>690343

The ladder is the most dangerous tool, it causes the most deaths and serious injuries. Being cautious with a circular saw is considered smart, being cautious on a ladder is considered cowardice.

>>690385
Seeing as I'm a noob, what tool would you recommend for cutting non circular holes in a piece of thin sheet metal?

>>690244
why wouldnt someone use a drywall knife to cut drywall? is everyone a limp wristed faggot now? its just a talc and paper sandwich. who would let someone cut into drywall with a power tool without even trying to use a stud finder first?

why on earth would someone use a saw to cut metal when a grinder or plasma cutter would work better? why are there shitty tack welds on that cut on the side?

>>690552
I've seen the old man go after sheet metal with a chisel and hammer, its old school but it's cheap and it works.

If it's on a smaller piece, glue it to some wood, pre-drill a hole (with an actual drill, use a metal bit but go slow) and use a scroll saw. The hole needs to be just big enough to slip the blade through. You need to use the right blades for any cutting job regardless of what you're using, so make sure that you aren't just using the basic woodblades that come with the saw.

Larger holes that don't need a tight turning radius or are on pieces that are too big for the throat of a scrollsaw, you can do with a hand held jig saw. Depending on the thickness of the sheet you might want to do the same as above and glue some thin waste wood to the back to stabilize the metal. Again-- get the right blades.

Any thicker and you really want to get a plasma torch or oxy-acetylene with a cutting tip.

There are nibblers and electric shears, but we all hate them because clean up is a bitch.

>>690556
When you're cutting a shit ton of drywall, Sawzall saves time and fatigue. Smarter not harder.

>>690552
>non circular holes in a piece of thin sheet metal?

It depends on how thin, how many, and how patient you are.

Tin Snips: Slow, and you can cut the bejeezus out of yourself.

Jigsaw or Roto-zip: loud, leaves rough edges. You can make it smoother by >>690552 clamping it between wood.

Laser cutter or Plasma cutter: expensive.

Air Nibbler: like tin snips with less carpal tunnel.

Custom made cutting die: Stunningly expensive. Good if you want to make thousands of identical holes

>>690713

Just use a reciprocating saw. Jesus you people.

>>690713
standard screw driver, knock hole use snips if smallish, use Andy Shears if bigger. Learn to use snips they are cutting tools, not hack,hack, hack.

You cut with them like scissors, not bolt cutters. A person who uses snips leaves an edge that is no more dangerous than any edge on sheet metal. A station wagon warrior is going to leave an edge between a high DPI hacksaw blade, or a medieval torture device.

And hammer and cdhisel on sheet metal is old school, if you are dealing with 14ga black iron or thicker. 26ga sheet metal use snips

>>690659
also kills blades and leaves a shitty edge for finishing it. If all you are responsible is screwing it up to the studs, use a sawzall. If you have to tape, mud and finish all the joints, you wouldn't be using a sawzall.

>>690828
Well duh. I've never used a Sawzall putting up drywall, personally. Just when taking it down for whatever reason.

>>690832
Taking it down? Sawzall baby and you guys get to humping that shit out to the dumpster.

>>690847
It makes me feel important when I get to use the power tools.

The plug socket

Jigsaw with a metal cutting blade. The saw itself isn't that dangerous, but the metal shavings come off like fucking bullets and they have ways to ricochet around regular safety glasses.

>>690244
I remember at 16 I would use sawzalls to cut off the kinks on handrails for skateboarding. I'm surprised I'm still alive after being around stoned teenagers operating this equipment.

>>691198
Then use safety goggles. Do you care more about looking cool than being able to see?

>>691472
>>691198
How about a face shield?

>>689684
Lathe chuck key.

>>691526
A face shield is good, but you should wear it in combination with safety goggles in case debris is deflected under the shield.

>>690332
Question, what's wrong with using the side of the wheel? I've been watching my dad do that for over 20 years and I've always done it myself and haven't noticed anything that could cause a problem.

>>691978

Those wheels are a consumable, you realize. If you're grinding with the side of the wheel for long enough, it's going to wear through and throw shards of grinder disk everywhere.

It's one of those things where yeah you CAN do it, but you really shouldn't...
