Great your sorted with the CAM side then and often that's the hard part so your off to a good start.

Sorry can't help with where to go for dedicated parts for this mill but for Motors and drives etc then Gary at Zapp is good start.
Ballscrews will depend on diameter size and pitch your wanting. To be honest I think your biggest problem will be getting ballscrews to fit and Big chance your going to need to modifie the base or bed in some way to make room. Unfortunatly I've no experience with these small mills so can't help here.!

If you do a search on here there has been a few conversions done. This company makes a kit:- http://www.cncfusion.com/minimill1.html Also there is a thread here :-http://www.mycncuk.com/threads/4524-...us-build/page4. .. Clive

i picked up a used clone a few weeks ago to do basic jobs but have done quite a bit of research on them all. It looks like you have the one with the upgraded spindle motor and a belt drive up grade which i think is the first mod people do. The good thing about yours is the fixed base as this is a little more solid than the adjustable one however a lot of people seam to go for building a hole new steel frame to bolt the base and the column to to get it even more stable. there is a good thread here about it and is what i plan to do

youtube has lots of cnc conversions and as mentioned there is a kit from cnc fusion which uses ball screws all round. Again i have been looking into ball screws but ideally you want one with a small ball nut which i have not found yet.

another common mod is to use ether a gas strut or counter weight on the z axis.
