Square Corner Without Dividers There is also a very neat way of laying out a square corner without dividers, and even the scale can be dispensed with if you have a straight-edge to draw by. Suppose you want to make a square corner at A, Fig. 37. Take any distance as AC and draw it any old way; this happens to be nearly 45 degrees. Mark the same distance each side of C, in a straight line as DCB. Join BA and AD, and the corner A is exactly square. HINTS ON LAYING OUT 57 The same thing is shown i...n Fig. 38, but with the first line EG at a very different angle. HG and GF equal EG, and joining FE and EH completes the corner. This can be done with dividers in the same way, but shows that when you have or can get a straight-edge of any kind you can make a square corner while you would be hunting up the regular tools. The best way to see all the workings of these methods is to take a sheet of metal of some kind tin, brass, copper, FIGS. 37 and 38. or iron and lay them out to a good scale. With the 6, 8, and 10 rule take 3, 4 and 5 inches, or 12, 16 and 20 inches, according to the size sheet you are working on.
