Alternatively, granite surface plates are available at a reasonable
price. Woodcraft currently shows a 12"x18"x3" plate, claimed
interferometry-flat to .00005", for under $80 (plus, admittedly, $50
shipping cost if you don't pick it up in the store, and whatever tax is
appropriate). I'm sure larger sizes are available from other sources
though cost is likely to go up faster than surface area if you want to
maintain that same flatness. (Then again, I suspect that this precision
is overkill for our application, so we might be able to trade that off
against area.)
