I've heard of this approach, and the large square is probably close enough
to give it a shot. I suspect I'd have to beat the hell out of the smaller
square to get is closr to right.

I'll report back on how it goes. I can probably use my machinists square
to get started. It's not clear how precisely I can draw and check the
lines, but over the long leg, I should be able to get pretty close. I may
also start by stoning out any nicks & dings, and then I can use a
precision
straight edge for the "base" of the alignment test.

The nicks and dings are a clue that they've probably been dropped a time or
two... generally the root cause of the problem. If you do the math you'll
find that a small movement at the corner will make pretty significant
changes at the ends of the legs--the corrections will most likely be in
minutes not degrees. As such you may not have as big a beating to undertake
as it might seem at first!
