Thanks David!
Decided to test out my tap guide. Some of the small gears need set screws. It's one of the reasons I needed a tap guide. The tap is a 1-72. Everything worked great.
Looks like maybe a pressure turning tool. Could probably be used as a tap guide.Actually I may have one. I need to figure out what this tool is. I'll ask again on the hobby machinest forums.
