Is this a reasonable amount of imperfection in a $60 machinest square?
I am guessing it is only difference of less than 1/32 of an inch but I
am not sure. Any advice would be much apprecaited.


A machinist square usually has a large heavy "body" and a thin
"blade". With that type of square, you wouldn't be able to put both
ends of the blade into the miter slot, because one end is embedded in
the body.

Exactly what type of square do you have? Can you post a URL to a
picture on the web from the dealer or manufacturer's web site?
