How to make barrel rifling from old steel bolts

Barrel rifling from using old bolt

[thesybarite]

Just imagine if this talented young man was in a modern, well equipped shop with adequate funding. Back in the day, (yeh, I'm really old) these were the kind of people who made the difference between a business being a success or a failure. Kudos to you young man.

Excellent work. 90 percent brain and mechanics. 10 percent machine. Pay attention folks. This is how things are machined. Not relying on computer assistance or another country entirely for machined parts is nice. This man is smart enough to comprehend this. Bravo!

Finally someone who knows how to treat his tools well (with cutting oil) ! Interesting video !

The number one cringe I get from almost every one of these Eastern metalworkers??? Sandals & bare feet. I got slagged while welding early in my career, and it was like driving a red hot soldering iron half way through my arm... Still have a hell of a scar 40 years later. I can't imagine some of the burns these guys have endured... Still, given the tools most of them have to work with, they are the most gifted smiths I've ever seen.👍

For all of you clowns making negative comments, you make it painfully obvious that not a one of you has ever made a rifle barrel. We anxiously wait to see your work. Good job, Yantoo.

I saw him twisting the high speed steel blank and i was thinking there's no way that's gonna be his button. Sure enough it worked! the blank already has threads ready to go in the receiver and if it's a good bolt like grade 8 it should honestly not be terrible. this is 500 year old technology we're talking about here guys, love to see it

[jamesmartinez]

I am completely amazed by these guys that have no formal training but work purely from talent and experience. Amazing!

[chadgdry]

now fire a projectile through it. BTW, this is the first time I have seen someone post their process for riffiling a barrel. Pretty cool.

[adamboylan]

Now that is a true bolt action. 😂😂. Great video sir.

[doodlegassum]

I love it how you guys always have a rooster nearby 😂😂😂😂

"What twist rate is this barrel?"
This guy:"Yes"

[davewebster]

At first I thought the rifling looked bad, but seeing how he did it it actually turned (ha) out really well considering all he had was a bent piece of steel. Good work!

[bookerol]

This was interesting and a good proof of concept. Using the HSS, heating and twisting, one could tailor the twist rate. Proper heat-treating, 4-jaw chuck, OD grinding, this would be usable. Food for thought!

Precision comes later, its the beginning of the process, that is very important, rest is patience and resources. Good luck.

Fun fact: The bullet stabilizing effects of Rifling were discovered by accident.
In the very early days of firearms, gunpowder produced a residue that would quickly disable a firearm as it was fired. An arquebus/musket was only good for 40-50 shots before it got so gunked up it became impossible to shove a bullet down the bore (remember: This was still the days of muzzleloaders), also making it a danger of exploding in the face of the shooter, so it needed cleaning quite often.
Cutting groves in the barrel was intended to make it so it could fire for longer before needing cleaning. At first, they were cut straight. But some guys discovered it was easier to cut the grooves in a spiral pattern. So when they test fired their product, it was found to be much more accurate than smoothbore or straight grooved barrels. It is said that they even outperformed an arquebus blessed by a bishop, with crosses marked in the bullets and dipped in holy water. The church doesn't concern itself with such mundane matters because "don't take the Lord's name in vain" and such. It' probably a legend.

Anyhow, I've been wondering for years how they did it back in the 1400s. And this man finally gave me the answer with the way he twists a square peg of HSS. Amazing how we take things for granted these days. I never imagined how you could do it besides a proper broaching machine and the modern rotary hammer techniques.
End result is a little rough. But besides the lathe, dude did it with no machines and thatis very impressive!

I am of average height & weight, 5'9" / 185 lbs but my knees hurt after watching these guys do so much work squatted down so far! Guss, you have to start those physical skills early in life have those abilities.

[ВладимирГужва-лы]

Молодец парень, напомнил мне нас в 70ых, мы тоже баловались этим, делали из гусеничных пальцев дт-75, почти на всю длину, и точность получалась довольно не плохая

[АлександрИвановичГоломазов]

Да.... Теперь я понимаю, почему производство ружейных стволов относятся к высокотехнологичному производству.
В кустарной мастерской к сожалению изготовить хороший ствол с высокой точностью невозможно.
Видео посмотрел с удовольствием.

Excelente hermano. Te consigues una prensa hidráulica y la haces lindo y más técnico. Te felicito por tu torno, no todos tenemos la oportunidad de comprar uno y hacer videos. Yo soy trabajado de empresas. Aun no he podido comprar siquiera el torno. Solo tengo brocas y calibradores. No tengo siquiera el taladro. Por eso te respeto y admiro.

[thisstuffido]

I love the simplicity of your rifling button. Nice work.
