Meh…it’s a welding table.

I’m a toolmaker by trade, I have a granite surface plate is I need absolute flat. Next is an aluminum reference/fixture plate, think of a cast iron surface plate, except in aluminum, about 30” x 54” long, and within likely +/- .003” or so over the entire surface.

Last is my 3’ x4’ welding table, 1/2” thick, maybe within 1/16-1/8”? Usually the aluminum plate is on it anyway so it gets used as a welding surface. [emoji4]
