By the way, the mill experts use a 1/2" diameter mill to recut the frame ramp. Ideally, a steel rod just under half inch should work well when it is covered with fine paper.

"Do not fix that which is not broken."
Yep. But 1/2 " should be fine, and is easy to find, I doubt the few thou added by the abrasives would matter... I couldn't remember the dia. and didn't want to guess.
Hi Lazarus & GBW:
Don't know what radius a Caspian receiver feed ramp is milled to, but the Ordnance Dept. spec for this is 0.236 + 0.005 inch for a mid-spec diameter of 0.479 inch. If Caspian's is close to this, I'd suggest finding a piece of rod, dowel, or tubing about 7/16 inch dia. and use duct tape to build it up so that, when wrapped with the abrasive, its diameter more closely matches the ramp. Then use GBW's spiffy guide to keep the angle correct.
I used this tape-wrapped-dowel (acutually brass tubing) method to lower the barrel bed in a receiver. Nice thing is when switching to a finer grit abrasive paper (which will be thinner), the tool's diameter can be increased with another layer of tape. And, with a fixture similar to GBW's to guide the tool, the bed ended up pretty straight, with little detectable (by me, at least) rounding at the ends.
Make a big pot of coffee before you start. As I recall, the bed lowering went at the rate of about 2 or 3 thousandths per hour - because only short strokes could be taken. LOL
