Im am getting quotes on the 8.5 x .75 single thread tap and die sets.
I believe these would be of great use when making fountain pens for the front section. It would allow you to drill a 7.9 or 8mm hole for the tap and that would allow you to pass a convertor through the hole.
Your body to cap threads would be 10mm and the inner threads will be 8.5 mm.
Would that be useful to us or would 8x.6 be better?
