I only need mounts for the y and z. The x ballnut will be fitted in a hole in center of the 50x100, you should be able to see it in the pic.

I can send you the proposed new drawing to give you an idea, but I would like hold off on actually making the z until I get the linears screws and mounts so I can double check the dims.

It will be probably a month or so if that's ok with you, what format do you want the drawings in(it's drawn in solidworks so I can save it in most formats).

Don't worry about how long it takes as I will probably be getting the linears before I have finished building the frame anyway.

As for the material We can sort that out nearer to the time, in the mean time I will be keeping my eye out for a good deal.

Does anyone know of a good steel box supplier, or am I better looking for local places?
