I'm working on a project, and have determined that both of my framing

the 24" one is out of square by more than 1/32" of an inch, and the 12" is
off by half again or twice that much.

I need something bigger than the machinists square for woodworking, but I
certainly can't rely on the old fashion stamped steel ones from Home
Despot.

Suggestions?

I bought a Lee Valley's stainless carpenter's square a couple of years
back and was delighted to discover that (as far as I've been able to
determine) it's dead-on square. I use it to square up my CNC router.

Almost as good: there's not a speck of rust on it.
