In my experience a lot of japanese machines use a 12mm head for an 8mm bolt, which always seems a bit strange to me. Everytime I measure an 8mm with my optical calipers and grab the 13mm socket it turns out to be a 12mm head

Shop I used to work in, these two rocket magicians had been filling up sandwich baggies by adjusting for a neutral flame, snuffing the flame, and filling the baggies after which they ignited them. Well since that didn't cost them enough fingers and eyebrows they went ahead and filled up one of the smaller trash bags from the bathroom, which turned out to be a bridge too far, since it broke the windows out of the office.

Until a couple of years ago I ran a 1976 Rolls Royce Silver Shadow. The brakes and suspension rely on spheres preloaded with 1,000psi of pure nitrogen. I've always refilled mine with the same nitrogen blend from the SCUBA tank I used to refill my PCP air rifles. Never had a problem with them.
As an apprentice i actually love these opportunities to learn. I'm into the trades long enough that my feathers don't get ruffled by doing the apprentice work, and smart enough to know that a wire stretcher isn't an actual tool lol They got me ONE TIME with that because my brain heard "wire **puller**" and it only occured to me once I'd said it out loud at the supply house... I was smart and returned with lunch and energy drinks😜
Ahh ...... 'prentice stories! As an apprentice Ion a fairly large building site I had to get there early, get the boiler on for brews at 8. Take the butty order, get the butties in for morning break. Get the dinner orders in and get the pie and chips in for about 10 sparks. Afternoons were for doing a bit of work! Well one of the parks thought he could get one over on me and at morning brew waffled on and on about the cream cakes sold at the shop next to the chippy ........ and come dinner time slipped in his request for me to nip next door and get him one "Cream Clit" Yeah I must have looked really dumb but as an apprentice I could hold a lie like a good'un! Dinner time came and the pie and chips were dished out to the smirks and the spark in question asked about his cream clit .... Face straight as a die I asked him if there was something odd about it as when I asked the lady in the shop she had said they were not ready yet and could I call back in 1/2 an hour? Well he stuck to his line and I said I was off to get it for him (nobody said anything) so off I pop ......... The next day they were all asking why I didn't come back. So face straight as a die I told them not that I had actually gone home never having even gone into the shop the first time but spun them the tale of me being taken upstairs and subjected to an afternoon of debauchery! My standing went instantly from dumb 'prentice to Superstud in one day!
I'd like to add a diffrent opinion of an aprentice, I do not appreciate the go and crawl into the back of a garbage truck and shovel it out moments in the feild, or go and lay in a snow bank and hammer the drums till they move
Since I started oxy-acetylene welding myself, I have read a lot on the dangers of the subject. Fun fact: The German wikipedia article on "acetylene cylinders" talks about the dangers of acetylene cylinders in burning buildings and how to deal with them. One Austrian source cited, states that it is practice to "shoot through" the acetylene cylinder with tracer ammo (Leuchtspurmunition) to cause a controlled combustion, rather than a catastrophic explosion. Another paragraph mentioned throwing a flashbang into the building. My thoughts when I read this: "Ah yes, another completely normal day in my life."
feel you, had a pretty long acetylene hose ripping on me once (a freshly cut beam fell on it) and i was like 20m far away from the bottle down some dirty nasty shithole xD luckily there was someone near the bottle to turn it off quickly
I always appreciate that you tell us the German technical terms. I'm Dutch though so I can already understand everyday German. Germans really do have the best words. Leutspurmunition...
I think it was in spring this year a acetylene cylinder caught on fire in a construction area in a town about 50km from here. They had to evacuate and get a sniper take a shot to puncture it to release pressure and make it burn out faster.
Having semi-controllably detonated an 8oz can of like 60% acetylene I can't even imagine what an entire welder's tank blowing up would sound like. When I blew it up I was convinced that I had lost my entire right hand and went blind & deft for several seconds(minutes?). Of course it was just shock, I was ok. I wanna shoot one now.
@Viscous Shear yeah I'm not sure why anybody would want to shoot a hole in a cylinder...acetylene cylinders have multiple fusible plugs in them that melt out near the boiling point of water (vs a burst disc that ruptures at pressure), which is their entire point. If the cylinder catches on fire or even gets too hot, the fusible plugs melt and release all of the acetylene to atmosphere.
Teaching the unknowing masses about the LH thread on gas fittings and then trying the screw the hose onto the reg right handed? Muscle memory is hard to fight.
2021 everything is deadly back in 1967 that torch was safe as pie in my hands as a 7th grader on the farm. Amazing how deadly it got sitting on the bench for 54 years... yikes
Here's a story for ya - A mate of my old man comes into the garage on a saturday morning (MOT repairs - old man) telling us some thieves tried to break into the safe in his office the night before.....Next morning he comes in, safe is intact, but the whole room is black from soot, nearly died of laughter!
Look at that Journeyman knocking that steel off with the torch head. Dont let him catch the apprentice doin that same deed lol. I learnt the hard way ha ha
I'm always gobsmacked by two things in respect to your vids. Your knowledge of subject, be it metallurgy, chemistry or whatever and your willingness to share all this understanding with the likes of me. Thank you. One thing I was taught on the gas, when opening the tap, open her all the way, as you did, but wind it back a nubbin so the handle is loose. That way you'll always know that the tap is 'open' cos it's loose in the hand. Hard stop 'open' and temp variations in the materials when in use can cause the tap to bind and stiffen up, making it difficult to close. For someone who doesn't know if it's open/closed they can think its shut when it's not, cos it's stiffened up some and, thinking it's stiff closed, start disassembly of the hoses on an open cylinder.
Oxygen tank valves are double seated. you need to open the valve all the way and close it all the way. Acetylene is just cracked open as the gas can explode at more than 15 psi.
@@millwrightrick1 only on high pressure cylinders, he's talking about the torch handle itself. Also I checked a bunch of cylinders using soapy water to see if this an issue and I couldn't find one that leaked past the valve when fully seated. I think the gas companies do a much better job of servicing bottles these days, vs the old days when people owned their cylinders and had them refilled instead of just exchanging their rentals when the truck comes around .
Tom Steemson from what I can tell from the vids i have seen is that Mr AvE works in the mining industry and travels quite a bit, maybe for a manufacturer or for a mining company as a problem solver when no one has a solution. He is good at a whole lot of things and expert at a few. Think - Special forces the A-team
Love the hesitation before knocking the piece off with the torch head. "Do I or Don't I? Do I do all this safety talk and then smack the torch head against the plate? YEAH, I DO!". I'm a back seater myself. Did I just say that?
Pro Tip, AvE - your straightedge should not be down on your workpiece because it reflects unwanted preheat flame back into the cut. You’re trying to use the minimum amount of heat that’s necessary to begin and sustain the oxidizing reaction for the cleanest cut possible. Weld some washers to the bottom of the straightedge to create a ~1/16” gap between the straightedge and the work and give the preheat flame a place to escape while you’re moving along the cut! You’ll make cleaner cuts within a wider range of all the dimensions you mentioned!
Come on man, I invested 23 minutes of my life to see you cut that thick AR plate. The only more frustrating moments of my life involve the phrase "but I have a headache".
The headache problem is easy. You offer her an aspirin and a glass of water. When she ask what those are for, just grim and tell her they are the latest sex toys. If that does not make her hot nothing will.
Unsubbing from this clickbait promoting channel LOL. also " im really tired tonight how bout tomorrow then your phrase when tomorrow comes..... unlike you tomorrow always comes
Not always, I tried looking it up a while ago, and the normal use seems to be that they are denoting "special". So it might be left-hand, weird pitch, tapered thread, or whatever, at least when it comes to fasteners. Gas lines are usually a bit more standardised, but it depends on the application. But yes, on oxy-acetylene, the left-hand connections usually have the notches at the unions. :)

oXI ENIGMAZ IXo go watch this old Tony's video. way more informative. I bet you could go out and pick up a torch after watching that video if you aren't one of them there idiots the world keeps inventing
My alcoholic brother spent a good 5 minutes showing me how to run a torch. I also had a pamphlet from the welding supply shop and a book from Forney so old it talked about using asbestos to hold in heat when pre-heating. I managed to cut up what I needed to without winding up in a burn ward.

Nitrogen in tires comes from road/oval racing. Pure dry nitrogen has a known expansion/contraction rate for a given temperature. So a driver can adjust the handling by adding or subtracting some from the tires. Works well for that. For a street car the sales pitch is that it can help keep the rims and TPMS sensors alive a bit longer by limiting the moisture in the tire to limit corrosion. The problem with that is most TPMS batteries die long before corrosion can mess with the pressure sensor and 99% of corrosion on the rim comes in from the bead.
@@Blazer02LS while using nitrogen in tires did come from racing,it was more for logistics than the thermal expansion benefits. The difference in thermal expansion of dry nitrogen and dry air are very similar. To the point the difference would be unmeasurable with the instrumentation a race team has at the track. So the teams options are to be tote a compressor, dryer and a power source to each and every track, or a handful of nitrogen bottles.
"We've all caught ourselves on fire. 1,2, a dozen times." As a welder I can confirm. Most of the times I've caught alight it's been from cutting wheels.
Dont wear boots with holes I have had burn marks on my feet and I know 3 smells by heart burning shirt, burning boot sole, and burning flesh/hair I have set myself on fire with cutting wheels too
When cutting thin steel like cutting a door in an overseas container , it helps to tip the torch in the direction of travel ; some times more than 45 degree's and keep the torch on the waste side of the line . scoring the line to be cut with a sharp tool will help keeping the cane reaction going .
Never ceases to amaze, Uncle Bumblefuck teaches me something every darn time.... Whether I want it or not. Thanks for doin what ya do..... (i won't tell)
Psshh, Anything is a hammer when needed on the proper occasion when nobody's looking. Tape measure on the end of a flat head, pair of locked visegrips, heel of my palm. Even a stabila torpedo level on the rare occassion finds itself banging something, because who doesn't like using an $80 hammer? Guilty on all acounts. Now go soap your brass torch head and check for leaks. Lol 😂
@@buillioncubes No worries there, quite careful. Lot of nerves in there and I've heard about guys pounding drives in with the heel of thier palm damaging them to the point where they can't open thier hand. Mostly use the hand attack on flat larger surface area's, when you concentrate that into a 1"x 1" space is where you can seriously screw up your hand for life. Thank you thou. 😉 SMW btw.
I burnt my hand with a torch,the skin just fell off and was burnt to the bone,it was black,took 4 months to heal and scabbed all the way through never again.
@@nigletthediglet4891 Same hand bitten by a dog,ripped it open again. Gloves are a good idea when using oxy Dont try to stop a monster dog attacking yours by putting your hand between them.
Back in the day, you could always count on the welding types to set off the alarms by delaying turning on the oxygen. Still you got another tea-break out of it.
By the time I went to trades school they had figured out that the little black wispy bits you get when burning acetylene without added oxygen are a fairly carcinogenic and that you always want to crack the preheat oxy a bit when starting a torch.
When I was about 10 I got really nerdy about chemistry. This was the 1950s so a wee lad could go and buy a 10 pound sack of calcium carbide at the local drug store{no idea why they sold it } and I took said Calcium carbide home in my hot little hands for some sperimentin in my basement laboratory. I had a 5 gallon galvanized washtub handy and tossed about a gallon of water in it and a tiny hunk of ye old c carbide and lit it , Not much happened. So, I upped the anti and added another gallon of water and a chunk the size of a softball . Mommy yells down it's dinner time and I figure , good , that will give it time to work better. About 20 minutes or so later , back I come to ye old lab and lit a match, with the intent of tossing it in the tub. Kaboom , flash of light , ears ringing Ireel around for a few seconds and my old man , who was a man of few words , opens the basement door and yells down , that's the end of the fing chemistry stuff. I was pretty sure he meant forever. The house had actually rocked on the foundation from the blast, Another one of the hundreds of times I should have been hurt or killed or at least deaf and God watched over me. I imagine he shook his head a while though.
I was always taught to only crack the acetylene open so that if there's an issue you can shut it off quick. Thinking about it, if there is an issue, probably just want to run away instead. Also I tip the torch just a touch forward so that it heats in front of the cut.
Was taught the 1/4-1/2 turn as well in the90's. Last winter finally had to apply it when the hose burst into flames due to a mig wire trim somehow sticking out of the red hose.
Thank you. You teach me stuff that I want to know, stuff that I never knew I needed to know, and you do it with a style that's deep, honest, reliable, and teaches the lessons of life in one of the best ways possible for me. You're helping me learn how to teach my stuff as well. We are better together.
The torch is always big enough you just got to get it started the oxygen finish the job. Once had to cut the spindles off a semi trailer to scrap it, 4" thick. The rest of the crew were taking Wagers as to whether or not it was possible to swing the gas axe like that. They're going to rent an off-road forklift to load the axles intact,as a plan B.
Do not use the torch as a hammer unless you want to buy a new one. I seem to recall that cutting at an angle may stop the cut part from hanging on. It may also be related to turning up the cutting oxygen pressure a bit. See 3 adjustments.
Im all blue balled here. Uncle Bfk teased me with some cutting porn, but pulled out when the tank dun run dry. Now I'm gonna have to surf those dudes at Weld.com, or firem up my own torch and do my own hand job... #FlameOn
I do a lazy leak check... after I connect my regs, I open, then close the valves while mentally noting the tank pressures. I recheck after 10 minutes or so. If the needles stayed reasonably put, I'm good. Also, try setting up your torch with the main valves so they're underneath the body when in use. This way, there's less chance of one's protective clothing "helping" by tweaking the valves. Also also, 1/4 turn on the red can is the stuff of long life. Years ago, I skipped the lazy leak check detailed above. I had a leak in a fitting which a grinder spark helped me find... I heard a pop and looked over to see a sinister little jet of flame coming out near the regulator. I nearly defecated, but with 1/4 turn, I was able to literally keep my shit together. Keep up the kickass vids!
I really appreciate the honesty in your videos. Its so easy to leave your failings on the cutting room floor, but therein lies the true value of your videos. No one was a professional on their first go, and there's no shame in the state of your ability wherever it may be, as long as you're getting better. Thanks Chris.
5:54 - The way I heard it.... It takes huge amounts of research and the very best engineers to design something idiot-proof. Idiots tend to be very motivated and highly resourceful.

Oh man. A reference to “Shake Hands with Danger” and “The Edmond Fitzgerald” in one AvE video. Gold. Pure Gold. Seriously if you haven’t seen the Shake Hands with Danger safety video, do yourself a favor and look it up.
that's a nice looking torch head ya got there. care do to any shameless shilling. I have only used the cheap-0 30 buck part store variety, and if you think about looking at it the knobs fall off.
Victor and Harris are the go to brands. I've had good luck with my princess auto knockoff of a victor journeyman although it's impossible to find tips for it.
+1 for Victor or Harris. A slight nod toward Harris if you're looking to run propane/butane/natural gas/or propane cocktail fuel gasses. Their torch design optimizes the lower tempetature flame providing more preheat per tip size
You summbitch you took my 10mm sockets. I know it, as they are so rare, that mine must have been the last on Earth! THEN YOU WENT AND LOST THEM, I demand recompense immediately. 😣😆
Acetylene such an exciting gas, I did a welding course after leaving school when a delivery driver was delivering gas bottles to the TAFE I scrubbed out a blue flame and filled the square tube for holding the filler rods and sparked it, the delivery driver thought he dropped an acetylene bottle off the truck and thought he was dead 💀 apparently a great opening tool for Metal boxes with the folding stuff inside
Hey, I've recently discovered your channel. It's absolutely marvelous. Onto the issue of the Teflon tape on the bottle : they are allowed to put it there because teflon isn't oxidized by pure oxygen at room temperature. That is because an even stronger oxidizer was used to create it : fluorine. F2 gas is much much much more dangerous than O2 gas as it will react violently with nearly anything it comes in contact with, including glass, which O2 doesn't touch afaik (but I'm only a chemist). PTFE is inert towards 99.9% of chemicals, very few can harm it at room temperature or slightly higher. Edit : whoops, I paused the video to comment and didn't see that you've addressed it :D
I was taught to backseat the oxygen, and just crack the acetylene a quarter turn. the o2 tank has a double sealing valve due to the very high tank pressures involved.
I like the crutch comment. I was learning to stick weld and the only thing I was any good at was sticking the rod to the work. I saw some guys dip their rods in the quench tank. I asked why and they told me it made it easier to strike an arc. Being firmly in the suck zone I was willing to try anything, first time I go to do it the old man in the shop calls me out and says "what are you going to do in the field carry a water bottle, also you just dickered those rods. Learn to do it the right way".
Never stand in front of gauges when opening the valve , I had one blow the glass off once , hit my hand , skinned knuckles bad , I always stand to the side .
The men get separated from the boys when a guy can stand on his head in a field, enduring fukall weather conditions, cussing a heavy piece of machinery, blue-wrenching a bearing without gouging the shaft, while extraneous combustibles grin at you and no fire suppression device in sight. BTW, I was thought that the acetylene bottle and torch valves should only be open 1/4 turn so that when shit hits the fan, you quick turn the valves and get the fuk outta dodge
Honestly the best choice. You don't want to be stranded in the cave. No guessing on how chaegeed the battery is, and no pressurized propane or butane to blow up.
Buddy, I know the difference between a regulator and a relief valve, I use them both every day. But your explanation of controlling upstream pressure vs downstream pressure just blew my mind with how simple that is.
Some of them do, Ford dealer I worked at had a machine they'd completely flatten the tire.... (While still on the car flat on the ground not lifted...... ;l ) once they went flat it'd fill them back up with 'nitrogen.. Using my noggin I realize they never changed the Nitrogen leading me to believe it was all a show since it was next to the window.
Cutting with propane using the correct torch (key operative there) is far superior to acetylene. It's not about the temperature of the flame, it's about how quickly you can get the steel up to temperature for the oxidization to happen. The BTUs are more important. Look for a "fuel injected" torch, which uses a venturi from the oxygen to "pull" the fuel gas through the head, resulting in a better fuel ratio. I've cut 6" steel on 2lbs of pressure from a grill propane tank.
I've cut 4" steel with the flame off because the plate was retaining heat. It's all about the oxygen jet and I'd say you need at least 30 psi to cut that 6" and that would be very slow at that. I used 80 psi jets for anything above 2" usually. Going lower psi isnt as much of a problem as going over and flaring the jet out.
@@onradioactivewaves That's always a cool trick. I was kinda hoping Ave would do that just for funzies. It illustrates the point further that it's not the heat of the meat that matters. It's how fast you can get her up to temp that matters, and a fuel injected torch with propane does that better than an equal pressure torch with acetylene.
@@pinkflamingo8806 yes acetylene is just too hot. Its nice to chop a car up quickly, but propane cuts plate nice. The heat of the cut release enough energy to sustain the reaction at fairly low plate temperatures.
@Kathleen Shaw my first torch was something called solid-ox which meant solid oxygen pellets you lighted & they gave off oxygen, you used Mapp gas, & heated part red, then cut off gas, which allowed oxygen to cut, o regulators, just simple dangerous fun, came out 40 or so years ago.
Try more oxygen in your preheat mixture. Your still using a carburizing flame. Small defined triangle inner blue flames, just not enough to tiny the blue to purple and get noisy. (Oxidizing flame) It’ll preheat to puddle temp faster so less overall heat buildup in steel and more localized to where ya want it for when the oxygen valve gets going.
