Thread: Hawkins plains rifle project

Hi R 93, The way I did it is I had already made up the barrel breach plug with the octagonal machined on it, so after fitting in the breach plug I set up the breach end in the 4 jaw chuck other end in the turning center. the pic shows the barrel and cutter, but I cut only half of the flat at a time, it was to hard to do it all at once. So the plug was my divider for cutting the octagonal and just used the hand wheel on the saddle for up and down, nice and slowly, fine cut. Homebrew.357
PS, The bike parts and gearbox in pic #206 are for cutting the rifling in the barrel.

Awesome. You must be patient.
When I seen the sprocket I immediately thought dividing head but did wonder how you measured it for a cut.
Hard case either way.

Hi, No ,not patient, just retired with plenty of time to waste, I mean the barrel was meant to be .450"cal and the rifling suppose to be 1 in 36, But 1 in 33" should be good for bullets, but not so good for round ball, will just use light loads for them and see.
