I was looking into how rifle barrels were rifled and was wondering if y'all know where I could find plans for a rifling machine. if they did it way back in 1800 it can't be that hard right?

I've seen cut rifling machines operate at HS precision. They are huge monstrosities. Just a quick Google gave me this;

Good luck in your project

I have seen some wooden ones and that's what I'm aiming to build, it's just a project and I'm not looking to mass produce barrels. something about being able to say that I built it.

quick explanation of different methods.

you win the lottery?? the older ways to do it are just as expensive in relation to the cost of setup today as it was way back when.

the price of machine tools has not changed and frankly i doubt it ever will. the only thing thats changed is the massive inflation.

back in the 1800's you needed the equivelant of a couple million in today's money to setup a rifling operation. you will need that same equivelant in money to etup whether your doing it the way it was done in the 1800's or the way its done today.

Maybe but there is more then one one to build an ak. The old machines look very simple but there aren't plans anywhere so building one would be difficult.

This machine can't cost that much to build, even if it was cheap. seems like too much work for a primitive barrel.

As I look around, I almost think it may be easier to do broach rifling or button rifling and not cut rifling;

Perhaps but the force needed to push the button through the rifle is from what I have read 10000lbs. broach rifling seems more within reach.

Cheever 09-24-2013 05:14 AM

I would think you could pull the broach through with some sort of hydraulic press

JayCody 09-24-2013 05:21 AM

Maybe a 20 ton press. Main issue here is where i would get a broach.
