Homemade cylinder for antique revolver.

Indexing each of the chambers and getting them straight will be a chore in and of itself.

Thinking that should be one of the more srtaightforward parts of the project. Set it up in a rotary table on the mill, find center and bore and ream that hole, offset to center of chambers and use degree marks on the RT to locate, bore and ream chambers and bore nipple holes. Now the fun part begins. Then again, as a strictly amateur machinist, it wouldn't be the first time lack of knowledge has gotten me into deep doo doo

I would think that the cylinder stops and chamber alignment would not be terribly difficult, bore the chambers first, index the cylinder in a hexagon fixture and then put that in the vise on the mill and cut with a woodruff cutter rotate the hexagon block in the vise and do the next one. change to a regular cutter and cut the taper to the notch.

The ratchet is going to be tricky to index, I would machine that separately and affix it to the cylinder.

I would think the jig would index the part from the centre hole and one cylinder (2 "pins") - moving the part and not the jig itself.

alternatively - machine the exterior of the cylinder, flutes and locking recesses etc, then ~ another jig ~ to locate the chambers themselves using the locking recesses as the datum points ...
