Still working on making the stand, but the tables are done. I have about ±0.008
per 12" on the diagonal, which was the worse offender; there were two "bumps" that were quite difficult to get minimize. Along the 4ft lengths, it is better than that, and the short 3ft sides even better, by about 0.001" less. Better than the manufacturer spec of 0.015" per 12". I only tacked the slats on the underside (along the entire lengths), not the top where the tab-and-slot meet. I didn't want to risk having those warp it since I'm satisfied with how the flatness turned out.
