          Hi Gary,
           
          Get a piece of material, preferably steel plate or the finished side of an angle plate etc., with a good straight edge on one side. Use your square to draw a line using the straight edge, flip the square over and check your square against the original line you drew.
           
          Regards

              I’ve always been taught and used Terry’s method quick & easy particularly on larger squares.
               
              Nobby I’ve not heard of a Bottle square is that what I know as a cylindrical square – length of ground tube with accurately ground ends. Though if you also know someone with a square that has not been dropped that should be OK to check against.

                  Glad the squares’s OK. How’s your foot?
                   
                  Seriously, I have a very old patent square, which looks wonderfully well made. It’s about 88-degrees. I have no idea what sort of forces must have been applied to put it so far out without otherwise damaging it. Perhaps I will have a go at milling the blade true one of these days.

                    Rob, where do you keep it, and how many mates do you have to lift it, 40 mm X 100m weighs a fair bit! Do you use it vertically, that must be fun? Ian S C
                     
                     
                    I suppose you ment 100 mm
