But, I rather doubt you need to remove the epoxy, and I strongly suspect that trying to do so would let some of the 'granite' fall out, either immediately or some time later. I would simply go diamond wheel for the lot.

Just how well EG on EG would work - I haven't a clue. Sounds bad ... but you can get the surface really shiny smooth. Maybe pressurised lubrication?

My opinion is this would work so long as there's a film of lubricant between the two. Without it, I can see the re-plasticizing of the epoxy and subsequent weld together due to friction. I guess alot of it depends on the weight and pressure of the two surfaces sliding together.
I too, don't work with EG, although I see it as a viable alternative to cast iron. This is interesting and if someone knows more, please enlighten us all.

The only machine I have seen that used granite was Excellon, and they used air, under pressure, as the "lubricant".
