Anyone know a good source for a tapered reamer to do your own 24 backbores?
I know everyone's 24 is slightly different, but I'm looking for the tool to
attach to a lathe to experiment with cutting in our own 24 backbores. The 24
is a tapered, but straight - meaning there is no "shoulder" arch as it meets
the throat.
The mouthpiece guy at Dillons told me he uses 3 different tools and of
course wouldn't give me a size or anything.
Anyone else figured this out?
