I wouldn't know about the quality of the couplings. I started with a manual machine and stripped it completely right out of the box. The parts I didn't use went back to Taig.
You're right about the angular contact bearings, you won't find them to fit 1/2".
I see some lathe work in your future. Don't worry about mucking it up, replacement parts are very reasonable.

Walt,
I checked out your CNC site! Brilliant work, that was gutsy to do what you did with the ballscrews. I bet part of your motivation was personal because people saying it couldn't be done.
I'm getting an 8X12" HF lathe soon, so you are correct about the lathe work I will see about getting the precision screws and creating my own supports and coupling. Maybe I can give them the poor student excuse and they might pity me enough to give a discount on the ultra-precision screws. I guess the only thing left is tons of gib adjustment and oiling. I really just want to machine some 1 thou tolerance parts
