did you use brand name measuring instruments to find the sizing?

 

The calipers werent super accurate, but the main problem really is finding a bearing that will spin at 200k and not ---- the bed. I'm waitin for my machinest buddy to bring his tools over and take proper measurements to a few thou at least.

 

ceramic bearings can be had easily

 

Priced them, they seemed to only come in Metric sizes and in 2mm intervals. Not to mention they are fawking 80bux!! Way to much for a 14b lol.

 

link to the bearings?
