And yes, I was obsessing about flatness, just for the fun of seeing
what is possible with how much work. I suspect that I've got it a lot
flatter than I need it, and that I will not maintain it to this degree
of flatness.

Oh, for my real answer... I have a hunk of Scarey Sharp(tm) granite. I
used that to test the top for flatness. I can slide that thing around
pretty much everywhere without it rocking, so that's probably flat enough.

I'm worried about flatness because I also use my bench for gluing, say,
chess boards together. That granite thing seemed to do it though. No
feeler gauges or anything, just making sure a piece of granite
approximately the size of 1/3 sheet of sandpaper doesn't rock anywhere on
the bench. I'm sure it's not up to the standard I just posted about, but
I'm too lazy to drive somewhere and find a set of feeler gauges anyway.
