So I picked up a King Canada KC-20VS2 (a BF-20 clone) and I'm on my way to a CNC conversion.

What is the current state of the art in:

- Spindle bearings (I'd like to see 6k-7k RPM)

- Belt drive conversion

- Quill removal

Some things I'm already settled on:

- ArizonaVideo99 ballscrew kit

- ClearPath Servos

- Ethernet Smoothstepper & Mach 4

- I've cut 1.8" (ish) off the front of the base deck overhang for more Y travel, but I'm not going to cut rearward or do a rear column spacer

- I'm probably not going to do the 1-shot oiler & manifolds, partially because I'm not sure the juice is worth the squeeze, and partially because I envision an eventual conversion to linear guides - but I could be convinced otherwise.
