My “Big Box Store Square” is no longer square. I would like to purchase a Starrett combo square. Considering an eBay purchase. With pics and all I can get a good idea of the condition of the square but not the accuracy. My question, can you re square a combination square? Should I take a chance or just get a new one from Starrett online?

Yes you can. Combination squares heads have small ridges either side of the locking bolts that can be easily filed with a small auger file. BUT a reference square must be always at reach, These two squares could be a great option:,42936,42944,42936

Also, there are other good manufactures of “old” Machinist Combination squares, I have seen beautiful Lufkin hardened ones, Mitutoyo and Brown and Sharpe.
