20 mm thick. That's worse than I thought from your picture. Well, not
having
any but the vaguest idea what this material is actually like, I can't
offer a whole
lot of help. I have a surface plate that is almost a meter long (24 x 36")
and it is 4" (101.6 mm) thick. That is pretty stiff. Anyway, if you
don't mind
using a second fixture plate that might be aluminum with the 25 mm grid
of holes, then probably a 100 mm grid would be fine. That sounds like a
lot of
work with the diamond core drills!
