Anyone out there made their own spindle, I'm currently looking into building one for my machine but having trouble with selecting the main bearings, I'm looking for two main bearings ( angular contact ) approx 1" ID, I can get them but all the ones that I find have relativley low rpm ratings (7 to 12 thousand rpm), I want to be able to go up to about 20,000 rpm, any thoughts or insights would be appreciated.

I have had the best luck with KOYO.
There is a very long, expensive story behind this recommendation, but to cut to the chase, KOYO makes (in my experience) the best quality bearing for higher speeds. I use them also in my MX motors for the crankshafts - 15,000 RPM.
As far as type, I assume you know to look at the ABEC# for speed ratings. This sounds like an application for the ABEC#5 or #7 bearings. Don't beat on them to install them - use heat/cold to fit them and keep them spotless....you likely know all of that!
ScottConsistency is a good thing....unless you're consistently an idiot.
