Chris,
I have never been totally happy with the 9x20 in terms of quality of cut. (But until recently I hadn't been happy with my 12x36 or my mill. I spent some time tuning both of them and am now getting great finish cuts.)
So, maybe I need to spend some time tuning the 9x20 and see if I can improve the quality of its cuts and get rid of the chatter.

However, through the CNC conversion, just about everything will be gone from my machine. The bed, carriage, cross slide, headstock, and tail stock will be kept, the rest will be made into a boat anchor.
I already have mine converted to a DC spindle drive. I will be using Gecko 320s, Servos, and ball screws for motion. So, as you can see, not much left of the original machine.
