LittleMachinShop.com sells the R8 spindle head part all by itself.

You need to buy or make everything else. Since no one really likes
the origional drive gears, that is no loss. make a vee belt pulley
set-up.

I am working on mini-mill (X2) and looking at changing it over to a
Vee belt, and adding a shaft lock at the same time.

I am also toying with the idea of mounting it on a swivel so I can
tilt the head. As you probably know, the mini-mill has a tilting
column, but the bug is that the head alone does not lend itself to
individual Z motions.
