Hello.
I have welded a steel table 1.5m x 1.5m for a lightweight cnc but the surface where
linear ways put on is not flat.
So i want to apply to this table epoxy and leave it upside
down on a big granite surface plate(2.5m x 1.5m x 0.36m / 0.001mm flatness) i have
so flat surface transfered to steel table after epoxy cured.

Also i want to transfer the flatness of granite plate to a plain granite slab with the same method because this big granite surface place is expensive and i want a cheap flat surface for various experiments.

What epoxy must use?
Epoxy must have very good mechanical characteristics with
very low shrink ratio.
