I have been thinking about threading tool. I watched Mike Peace’s video and that provided good info. His recommendation was 16 tpi. I know you need a good hard wood for threading. I thought I read at some point that the coarser 10 tpi threads worked better. What is the recommended tpi? Also the Sorby has a sizing tool. Is that tool worth the extra cost”? A threading jig is too many $$$ for me.
