I was going through some of my multitudes of boxes of stuff and found a set of thread cutters by Crown Tool. They are 20 tpi and never used. From the looks of things I bought them at Woodcraft on clearance. New they were $60, I paid $30. If anyone wants to give me $30 I will pay the shipping to the new owner. I don't have the attention span to learn how to use these. I posted here since they are only of interest to us with the spinny disease.
Sold to Jon.
