D.C. An interesting idea ( from previous posts I realize that you may be "biased" towards epoxy granite) would a granite gantry be very heavy?

I suspect a granite gantry would be far better suited to a fixed rather than moving design (fixed being my "bias"), but the preference on this forum seems to be for moving gantry, mainly I suspect due to space limitations.

I have a good friend who has a fibreglass factory who has an injection/vacuum unit and whilst I have not asked about granite I feel sure that it would be no problem for him to make it the various gantry components complete with any correctly positioned captive fixings that may be required. Just a thought.

Fivetide, if you really want to get this off the ground and none of the real experts want to get involved, I would be prepared to act as leader/coordinator although I would still be looking for help/constructive comments from those experts. G.
