I have gathered a lot of 1/4" and 1/8" shank tools so I must have the 1/4" chuck.

Starting at the beginning of Jeremy's series on the self build spindle - he is using an ER16 straight shank milling chuck. I checked and there weren't any imperial collets listed that I could see. I'm now searching for imperial milling chucks similar to the ER16 that might be made to work. I'm not afraid to run it through the lathe and make a mess! :heehee:

well it was running! (& as I have it at the minute, I can confirm it really is that quiet)

The collets that come with it are 2mm, 3mm, 3.2mm, 4mm, 5mm & 6mm.

I'm considering buying an extra Proxxon 6mm collet & boring out the extra 0.35mm needed! (because if I ever need to use a 1/4" bit...it'd be for 'grunt work' & therefore accuracy wouldn't be key, so the little runout I cause shouldn't be a problem! )
