Tube size

[tazhunter0]

The shop near me has some kits called " New series Rollerball pen ". I have bought a few of them and like them but I have a problem now. The last 2-3 kits I got didn't have the tubes in with them and they have no spares. They where very busy the other day with customers and didn't know what size tube they took. I know I use a " V " drill bit when drilling the blanks. 10mm tubes are too big and 3/8 is too small. Is there anything in between these?

Thanks
Chris

I can't find a size on their website but do have some of the kits in the shop and would be happy to go measure if you need dimensions.

I recently discovered that tube size can be a little tricky. The tube OD and ID need to be known. I found tubes for what I thought were essentially the same kit from 2 different suppliers, to have .002" wall thickness, but the same OD. That can affect bushing diameters and hardware figment. Yup, I'm a noobie
