Why does nobody tell new guys to check their square against a dial indicator before trusting it
I spent 6 years building face frames off a combo square I bought at a flea market in Akron for 4 bucks, and one day a cabinet fell apart on a job because nothing was actually 90. I grabbed my Starrett and a feeler gauge and the blade was out .018 over 12 inches, which does not sound like much until you stack it over a 42 inch tall pantry. What tipped me off was a guy at the shop in Cleveland running a dial indicator on his square and just laughing at me. I felt like an idiot because I had blamed my saw and my fence for months. Now I check every square I own twice a month, and two of the four were off right out of the box. Has anyone else caught a bad square this way, or am I the only one who trusted a tool for way too long?
