How do I rifle a gun barrel?

Question

I wish to make custom barrels from steel rod stock. How do I rifle them after I have bored them out?

Answer 1

Go get the book ''Foxfire No. 5'' from the library...
it shows how they did it in the OLD days.

I think even JD would be impressed to see what these old guys did with basically wooden reamers.

Answer 2

I am not sure if you are asking about the rifling, or lands and grooves, inside the barrels. If that is the nature of your question, then the answer is most but not necessarily all machine guns have rifled barrels. The Uzi submachinegun has 4 grooves with 1 turn in 254 mm (source 1); a Swedish submachine gun has a rifled barrel (source 2). Larger machine guns are rifled, but there may be exceptions. Carbines are rifles, usually equipped with a shorter/lighter barrel, but usually rifled as well. The rifling gives a rotation to the bullet, which gives it a more predictable trajectory. Hope this helps!

Answer 3

As a Gunsmith, I can tell you up front that unless you are a Master Machinist, with extensive experience in actual barrel making and have $100-$120,000.00 for an industrial quality horizontal tooling machine, you might want to look into another line of work. In order to make modern rifled guns barrels it requires the use of a computer driven tooling machine with tolerances that measure in 1000th of an inch increments. It is virtually impossible to do by hand. Technology has far advanced past the olden days where muskets and black powder rifles were manufactured using hand cut rifling. In this day and age, modern rifle barrels are made by boring the the hole and cutting the rifling in a two step process, all completed by computer assisted drilling/tooling equipment I mentioned before.......

Answer 4

I have 24 years of machinst experience, when I retired I was a Journeyman Grade 4. I have never operated a rifling machine, but I feel certain I could figure it out with some trial and error. If you have no machinist experience what so ever, it might be a good idea to start learning before you buy such an expensive machine.

Answer 5

A friend of mine many years ago made his own rifles, including the rifling. He actually made a fifty cal with a barrel four feet long. He was a bit crazy.

He was also a professional machinist. His guns worked just fine.

This is not the sort of hobby you can pursue without considerable risk. An error can be deadly. I recommend you visit a gun shop and ask where to find a good gunsmith. The gunsmith may be willing to instruct you, or perform the work himself. That is, of course, if your intentions for this weapon are legal.

Good luck!

Answer 6

There is a reamer that's specially designed to do this. It's pretty expensive machinery. I'm not sure if it's someting you can do in your garage without a lot of expense.

Answer 7

I seriously doubt you have the skills necessary to make custom gun barrels because if you did, then you would have heard of a "rifler".

Answer 8

you must have a barrel rifling cutter you can get them a good gun company

Answer 9

You don't, It ain't going to happen.*
