Very interesting. People may disagree on some things but the point is to see back to basics of metallurgy. If you’re in a pinch for a custom bolt this would especially be an option. My grandfather who was an apprentice machinist in Germany would never let me heat that material in a lathe chuck though… thanks for sharing your skills.
After 40 years of being a machinist, i still die inside whenever i see this. Zero precision control over hole size. You would have to re heat treat that material for it to be proper. But....🙄 In a pinch or on the farm, PERFECT. Cause it works better then nothing.😋
I don’t know… I’d be putting as much relief into that broach as I could, undercutting, pecking and redrilling, whatever the hell I had to do to keep from heating up the damn bolt. 😂
Huh? Dictionary definition: "the degree of hardness and elasticity in steel or other metal: "the blade rapidly heats up and the metal loses its temper" "
It's very dangerous to leave a chuck key in the lathe chuck when not using the lathe, if the lathe is started foe any reason the key will fly out and possibly kill some one in the workshop.
This is not the way… You’ve just improperly heat treated the head of the bloody bolt and left the threads soft… creating a stress point where the two meet. Drill the hole slightly deeper or undercut the hole. Cut the hex “broach” nearly in half so it only has three points and grind clearance angles on the back. Broach half the hex shape, rotate the piece 180 degrees, broach the other half of the hex. Use the same drill to remove chips as often as needs to decrease the amount of force needed to push the broach in. Static broaching is no joke… those chips packing into the bottom are enough to alarm out a fair size CNC machine if the tool of workpiece doesn’t push back first.
Ruin the temper in the chuck jaws and the bolt total abuse of expensive machinery as usual why didn't you just take a hammer and use the allen wrench as a broach and beat the hex in there at least you would not destroy your lathe chuck jaws crude

Thank you bro😍
@@TK-Thawngpi your hands on skills are a dying art. Not everyone can afford a CNC machine!
Nice work by Wow Mechanics 1
You see a an expensive precision machine tool - I see an anvil.
Totalmente de acuerdo ,una bestiada!!!!

Wow 👍👍👍🙏
Ruin the temper on a very expensive lathe to make a bolt. I don't think so.
I think that chuck has some thermal mass, have you ever used one that big? Temper is the wrong word by the way...

@@buddyboy4x44 Ahh, the dictionary, where all detailed understanding of metallurgy is stored...
Helpful thanks 👍
The heater should use an induction system 👍👍
Single cutting edge broach.. nice work..
Nice
Sir a vertical punch machine i think good to make alen key hole hexagon type.

And holding the emery cloth like that is a sure fire way to lose your fingers at some point.
@@chrishartley1210 Fully agree.
Let’s hear it for a generation of machinist without stumps. 🤣
OMG chuck key warriors... Give it a rest. (Here comes a lecture... One time in my shop...)

This is not the way…

I think it's better on hand screw press but it's ok
Bravo, useful genius idea, thanks
Next project..."Use angle grinder to trim nails"

Why not just buy a roto broach won t need to heat head of bolt
doesn't look like the holes deep enough to get a decent torque value.
still. pretty cool though.
They’re not cheap but you can static broach a hex on most machines if you grind/EDM your broach in half and just punch, index, punch.
Why not just use a dead soft aluminum bolt? Save the heating step and end up with an equally inferior product.
I don’t know if they even understand how hard they’ve just been roasted. 😂
La fregó así calentando al rojo el calor pasa a las muelas del Mandrill y se deforma😢
I have a free, working EDM in my shop. Pay for transport and it’s yours.
That’s not good to heat up the jaws.
Why?
Because the jaws could soften.
My opinion 2
Показал как не надо делать.
Not the same piece coming off the machine, tested and shown.
I found your chuck key!
You are a barberian !
Please don't insult barbarians.
Thank you bro😍

Lathe forge.
Nice working

Que buen tornero!!! Trabajando con la amoladora sobre la bancada y luego calentando el plato !!! 😂 Una vergüenza!!!
