Kluber nbu15 is the usual, fill no more than 1/3 of the space between
each ball. Generally I'll completely fill one space, note how much it
takes, and then I'll suck 2/3 of it back out before finally applying
the proper amount to the rest of the spaces.

Another way I've heard is to use mobiltemp shc-32, mix it with
acetone, dip the bearings in it and then let the acetone dry out, I've
never done it this way so can't really comment further except to note
that I see no reason why one couldn't dispense with the acetone and
simply apply with a syringe the same as above.


PT,
I've recently upgraded controllers in my old BOSS series I machine. Next
on my list is a spindle rebuild/upgrade.

I know how to do clean work, but I've never rebuilt anything as precise
as a spindle must be. Two questions:

1) Am I better off just 'biting the bullet' and letting a spindle house
re-do it, and
2) Can I get that spindle to reliably do 6Krpm with the right bearings
and lubricants?
