Can this be repaired? How to balance it?

Good news is that C8 ER11A 100L Collet Straight Shank Chuck Holder finally arrived,
and it`s good quality. I also ordered dial test indicator to help me in my future spindle build,
and other project... very handy tool.
Cheers!

P.S. This topic is watched (by the counter info) but it`s been a while since no one write here.
Please help me with all my doubts and questions above.
P.P.S. Those bearings from above... can they handle spindle rpm?
Without doing a google on a bearing site I cant tell you if they're suitable. However whatever bearings you use will need a preload on them to stop them from skidding. The best bearings to use (apart from a double row AC bearing) are magneto (single AC bearings) bearings and preload them with something like bellville washers.
