Forged Gun Barrel - Method 1 

Can’t wait to see you try and blow em up!

Destructive tests of the differing methods of forging a barrel might be interesting .. I'm guessing that although Whitley's method could produce a barrel faster, wrapping a bar around a mandrel would produce a barrel capable of withstanding higher pressures .. Loving this entire series, sir!

Good golly Sarge. That folded square technique is a stroke of genius! Two to three of the basic steps of making a barrel, done with a single folding and welding. If you want to keep from collapsing the hole, a good technique is forging out a long round-stock mandrel to pound through it. Saw it on the video before me, seemed to work pretty good.

Completely forgot I had some of my Dad's Foxfire books, and I have #5! Thanks for the reminder and this great video.

It's so amazing too think that they did this back in the day cool man

You are one heck of a good blacksmith. I can tell you're the real deal

I have both of those books. This is gonna be fun to follow. 👍❤️⚒️😉

SHALL NOT BE INFRINGED!............... Ur a hero dude! if someday guns be totally banned. U can do one out of some metal pieces!

Fantastic work!

You would love where I live.. You can dig up Anthracite in my yard. I live in North Eastern PA where all the Anthracite comes from. I live 1/4 mile from the mines entrance.

please document the rest of the build.

Awesome!

very nice

What does the borax do?

Thank you for your Service Sir.

Cool

👏👏👏👏👏👏👏👏👏👏👏

Hmm. Interesting... I always wanted to make a wrapped barrel . A damascus barrel as they are commonly but wrongly called. I'd imagine the bore mandrel would be the hardest part to make or aquire. Forge welding thin strips of steel together , while tightly wrapping them around the mandrel to make helical layers . Building up until you have the desired and uniform wall thickness and an undersized bore. Rifling can be made by continuing with the mandrel work or cut rifling ...or leave it a smooth bore if desired. Note a shotgun barrel is not just a tube. It has an internal constriction ,called a forcing cone at the end of the chamber. Plus at the muzzle end, between 6-10 inches back from the muzzle itself, is an area about 3 inches long that is not polished as well as the rest of the bore. This area slows shot cups and wadding, causing drag which eases seperation of the projectile payload from the cup . That area is not used in slug guns made for sabots . This is a big reason why shot is not recommended through them. Foster slugs are slightly under sized , and utilize that area to make a good projectile to bore seal. The meplat area of the slug slows down faster then the base , so it expands the slug. At least when the barrel is made correctly . Very cool experiment . My only gripe here is the " proof loadings ". They are not proof loadings ,they are just overpressure loads. there is a formula to follow to say it is proofed. Specific levels of over pressure are used to know the gun is safe with all commercial ammunition, yet does not induce structural issues. Called a red pill , it is loaded to be %70 percent over pressure versus a standard factory loading of the ammo type. The sequence is factory , plus %30 , inspect then plus %70 , and inspect. Magnetic particle inspection is done after proofing to look for microscopic cracks and flaws like internal stretching at the throat . A borescope with high magnification can be used but is less effective than mpi ,but far better than no inspection. Good video, it made me think

How about some gloves, apron and eye protection. I have seen some real artist on the anvil.

Anti gun screeching intensifies

Thats fascinating Jarod , I have wondered how barrels were made and you are going to show me at least 3 methods! Be watching all of them, you can bet on that!

This is nothing new. They were making barrels like this for 200 years. Just now we have better steel to start with. Nice work. Should hold with Black powder. Smokeless load might be different.

Awsome work! Havnt seen this method before

Hell yeah! I’d like to have set up like that one day! More power to ya, keep it up!

Wow 17 min and not first :)

this is a fun experiment

When you start your testing I have a 0-1 tenths mic you can borrow That will tell you if you have any swelling

Awesome

good job .. whats the material you spread on iron .. whats the powder ??

Will get it sooner than layer
