Well, I had a few hours on Sunday and was BLOWN away at how easy this part was to make. Bottom line: I never made them on the manual machine but rather spent a few minutes (!) and had them programmed and turned on the Tormach CNC lathe! It is incredible how easy the conversational programming is to use!
I'm going to LOVE this machine!
