Hi deano
This is what I ended up doing, as buying the ballscrews, ball nuts, bearings and couplings from Chai's standard offerings seemed the cheapest way. I had a rough idea of the cut area I wanted - had to cut guitar bodies and guitar necks which are approx 575 - 660mm long and then estimate how much is lost from the X and Yaxis due to the gantry.

The guys on this forum were great in advising on suppliers they had used with success and on material sizes. On my x axis (longest) they are 20mm dia supported round rail and 16mm dia rails on the other axes.

BTW I've started playing with Sketchup and found a great set of tutorials here http://sketchupforwoodworkers.com/
