Thread: Rifling thinge upgrade.

Hi all, Had a rethink on my barrel rifling setup as I could only cut rifle a left hand twist, so using the sine bar method I can now get a twist from 1-18 to 1-70" and right hand!!. I had a meter of mild steel 1" round, an old brake cylinder was machined to slide on this and attached to a bit of square ali with a slider setup driving a loop of bike chain to drive the rifling cutter rod," must have bike chain". The round bar is mounted at the back of the lathe and can be raised up and down to give the different twist rate by cranking the sliding head holding the cutter rod. Hope you all under stand this and I don't know if it will work yet, waiting to get in some stock to have a go. There`s no such thing as "Can't do it". Pics of the setup. Homebrew.357.
