Surface plate stand.

Level No stabile Yes. I leveled it when I installed it. Other than something rolling off I don’t need it to be level I need it to be flat.

A granite plate is to be flat, level is an option. Unless your plate is in permanent location there's no point leveling it. I see a lot of people worried about leveling the plate, but they have it on a stand that has wheels, which they move around the shop. Every time time you move , there goes your level..Abomb79 has a video on modifying his plate stand, his on wheels.

I'd like to level it so that I can use it to balance my surface grinder wheels.
Jeff (@Janderso) turned me onto this idea and I have since watched a video by Stan of Bar-Z Ranch where he puts a shop-made arbor and a set of 2-4-6 blocks on his surface plate to balance his wheels.

See federal spec here: FedSpecGGG-P-463c

Support specifications are clearly defined in section 3. Plates need to be supported on 3 points. They are not Bessel or Airy points. Hope this helps.
