the Zeester
I had a mini-mill and a mini-lathe. No Sherline.Now I have a larger lathe and mill.For years I'd thought about Sherlines. I'm still not sure why I didn't go that route.

As for diameter, I usually look at the drill chart (I know, Marv does the formulas in his head, its easier for me to have it printed out) and look at the numbers in the columns for brass and steel, and compare that to the major diameter of the thread. Then I'll take the diameter down below the major diameter about the same amount as the drilling would take it above that dimension. That seems to work well for me, for most work. If the thread is going to be under a lot of load, I'll take less off.
