I'm working on a project, and have determined that both of my framing
squares aren't square. I have a precison machinists square I checked them
against, and the 24" one is close, but the 12" one is way off. As a
guess,
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?

Tune up what you have...
