Why is there such a muddle of drill bit sizes required to make pens?
A Senior Gents lists the drill sizes as 29/64" or 11.5 mm and 37/64" or 14.5mm.
OK I had the 11.5mm drill bit and so bought a 14.5mm bit. The tubes would need to pressed in with a hydraulic press!! So I bought a 29/64" bit and had to order a 37?64" bit. 29/64"hole is fine.
So why the alternate metric sizes when they DO NOT WORK????:((
I see a US site has its sizes for one of their fountain pens listed at 0.492" and 10.5mm!! Sheer infuriating bloody lunacy!!!
Perhaps the best way to avoid frustration is to limit the types of pens we make.
