Gordon,
Nice to know there's another DIY CNC builder here in WA! I'd love to see some pictures of your progress.

Two sections of 65x35 welded together will give you a flat (if only!!) face 130mm high which might give an acceptable separation for the rails. Then you have to work out where best to place the ballscrew. I'm considering using something like 2 lengths of 100x50 steel box section on their sides at top and bottom for holding the rails, with an upright section between them which is set back to make room for the ballscrew to run between the rails and directly behind the Z-axis baseplate. This would be good and rigid (at least for my wood-cutting machine), eases the design of the Z-axis unit but is not something I've seen used in practice. Maybe the experts can see a flaw in this idea that I can't!
