Machinist Question: What's Best Way To Reduce A .450" Forster Pilot To .447"?
I need a Forster pilot to fit .45 Colt so I can trim the brass in the Forster Case Trimmer.
A #452 pilot is on indefinite backorder from Forster. No idea when it will arrive.
Midway had a #455 pilot and it arrived and is here on the bench. But it won't fit into sized .45 Colt, though. I assume the pilot is hardened.
I have a drill press, files, a Dremel and various stones for the Dremel (i.e., no lathe or mill).
A machinist question:
Idea #1 -- poor man's surface grinding
- Chuck the #455 pilot (published diameter is .450) in my drill press
- Insert a cylindrical grinding stone in the Dremel
- Turn on the drill press so the pilot spins
- Turn on the Dremel with its stone spinning
- Hold the Dremel vertically so the side of the stone is parallel to the pilot
- VERY CAREFULLY touch the spinning stone to the spinning pilot
Is that an acceptable way to get the #455 pilot from .450 to .447 (which is the published diameter of the Forster 452 pilot).
I need to remove .0015 to reduce diameter by .003, right?

Is there a better way to do it?
I don't think holding a fine file against the spinning pilot will work if it's hardened.
Times are truly dark when everybody -- including Forster -- is out of #452 Forster pilots. :wink:
