This is a small (2 1/2") plumb bob that I turned on my lathe then engraved. The hex sides are 1/4".
Hurrah for microscopes! Next step is to work on making my turnings cleaner!
Ray- yes I have a power feed. Still trying to figure the whole thing out! We need to sit down for a "serious" chat on the subject! You were one of my inspirations for getting the lathe anyway.
