Thanks Rodney,
The ball screw for X axis was "shoe horned" into the saddle. I added small linear bearing ways to replace the dovetail ways, then used a solid steel plate for the cross slide.
For the Z axis, I machined two mounting surfaces to hold the bearing blocks at each end of the screw. The machined surfaces are on the front face of the bed of the machine. The nut is attached to the Z axis saddle using a sort of "w" bracket so that I could put a cover over the screw.
Sorry, I don't think I have any construction detail pictures. This machine was built pretty quickly in the free time I had here and there.

You have given me some idea's for my enclosure.
I cnced an Hafco AL-50G which is pretty much the Australian version of yours.
I would be interested to see how you did your ballscrew on your cross slide.
And your Z-axis nut connection etc.
Do you have any more pics?
Cheers
