So not sure if this should be in the EG section or not, will place it here and see if mods move it. The construction of this will be done with concrete using 52.5R grade, sand, stone (basalt) and superplastifier to assist the mix / flow. Estimated weight of the machine will be around 2 ton when done.

Some initial reading material of how the design came to this can be found here - BUILD LOG: Thor, or should that be Zeus?

Since then, the design has changed many times, pics below. For reference, I have put some of the pics of the rails and ballscrews for size reference. Spindle options are still being considered. Currently its drawn with a 4KW Chinese spindle. No ATC. This may change. The other design goal was to run this from 220V @ 32A single phase max. Motors will be 1.5KW for Y, 750W Panasonic Servo for Z and X.

Thoughts / comments / concerns welcome.
