well, thanks for that info. That thing is so quiet I'm not convinced it is even running ... I don't see any cuttings!

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:
