I have to drill a 37/64" flat bottom hole in the end of a 2 1/2" long
piece of 1 1/16"AF hex bar that is chucked in the lathe, to a depth of
0.600" +0,-1/64 and then thread it 5/8-18.
(I'll be making about a dozen parts).
I will be using a drill bit with a 118° point.
The issue is: how to get the bottom flat and at the exact depth.
