Don't you just love the pen kit manufaturers?
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.

A pain for sure. When I buy kits from timberbits and looking at a specific kit I can see down the bottom of the page it lists the drill bits I need for ghe kit. I just add it in my order. Ive also got a list of the weird sizes I already know I own so I try not to double up

Put a new door on the bedroom last week. Went to install the door knob. Required a particular size drill bit. Off the Bunnings and every other hardware store nearby. Don't make that size bit. Had to go under size and file it up to size.

I dont even look at the sizes anymore, once bitten twice shy. I measure every individual tube with verniers and then find a drill bit the required size using the same verniers.
I leave the commonly used sizes on the bench beside the drill press, but sometimes have to look further for an odd size.
If I rounded up all my drill bits I reckon I would go close to filling 2 X 20 liter buckets with them .Brad.

It is nearly impossible to get the right drill size for some kits - either too big or too small. I opt for the small bit and then open up the hold to the desired size with a round timber or metal file. Takes a bit longer but you end up with the right size hole.
The other annoying thing I have found lately is that the ring on some pen clips is too small for the cap. This means having to file it out. It is a pain as they should be made to the right size to start with.
