I have been working on a Churchill Fountain pen today. The drill sizes are supposed to be 31/64 and 33/64ths
I didn't have those and so I have bought them.
However when I drilled the longer blank with the 31/64th drill bit the tube just rattled around in the hole, suggesting that the hole or the tube were the incorrect size. I glued it anyway to see what would happen, and sure enough there was a gap between tube and blank after the glue had cured.
I turned the blank down to the brass tube and the tube measured just shy of 12mm, quite a bit less than 31/64ths, so I used a 12mm drill and used another piece of the blank (solid green acrylic so no matching problems) and it fitted perfectly-pen completed!!
Has this problem happened to others?
I can't understand why the instructions as to the drill size were so way out.
