I have been thinking hard (too hard) about picking up a threading jig. I was looking at several tpi's.
16 seems to be recommended by many as a base.
18 or 20 seem to be next for hard dense woods.
I will be doing smaller items, boxes . Ring size through probably 3 -4 inches. Mostly 2 1/2 - 3 1/4.
I turn mostly native woods to ohio, but open to other. Want to start with some harder exotics. Most of the work will be standard hardwood.
What tpi do you find works best for boxes of these sizes? Also, is there a tpi that you found did not work for much?
Thanks
Michael
