Thread: Making a Sharps Barrel in my lathe.

Well it seems I`m not right also, my bore is .445" and cutting rifling out to .458" but for 45 cal it should be .450" to start with. So as I`m rifling know will finish it to .458" and then hone the bore out .450" to get it right. To set up for rifling the two ali blocks are fitted on and the base only of my x/y vice is mounted on top, to this my gear box assy is clamped. Two brackets at the back of the lathe are used to fit the length of bike chain drive for the gear box and a loop of chain is also used to wind it up and down the lathe bed ways, its bolted to the vice base and a small bearing jockey under the chuck with crank assy fitted at the far end, which drives the rifling cutter through the barrel. The barrel is set up with breech at the left end on the lathe and this is where you start cutting from, pulling the cutter through with it up, then down going back. Once you get some fine chips at number one grove, up and down 25 times and do the other 5 groves the same, only adjust the cutter after all are done. Homebrew.357.
