You are talking about grinding the OD of one of these bad boys?

Yep/ That's the type.

Make a widget to hold a small angle grinder on its side, with a pivot and a
screw for advancing the grinder a bit at a time. Make it so that it will
work clamped to a drill press table.

Put the drill bit in the drill press, and push the bit up and down past the
spinning grinder. Advance the grinder a bit at a time, and stop to check
the progress often.

It works. I've done it before. I am a bit "Rube Goldbergish" at times.
That comes in handy, for a homebuilder.

Of course, if you know someone who works in a machine shop, he could do the
job in a tenth of the time. Where's the fun in that, though?
