I just purchased an older (25 years). I want to make a CF shaft for it but I believe he used a 3/8 11.5 tap ( correct me if I'm wrong please) I'd like to find someone that could make me a phenolic insert with a 1" OD. Anyone capable out there?
I have sanded plenty of different carbon shafts, the Cynergy is the most finicky, you will get to the solid black shinny inner wall very fast, I don't recommend it just food for thought.
