. ABC OF THE STEEL SQUARE 59 



case the square is transferred three times, just 

 as though the rise and run were both three feet ; 

 the difference being made by dividing the odd 

 foot into three equal parts of 4 inches each and 

 adding one part to the blade, thus making the 

 gaugt- point on the blade 16 inches instead of 

 12 inches, which regulates the extra length and 

 the change in bevels. A little study on the part 

 of the reader will reveal to him how the square 

 may be set to gauge points so as to make a brace 

 suitable for any rise and run of any right- 

 angled frame work. 



A brace intended for equal run and rise of 

 four feet is shown at Fig. 32. Here we have 

 the fence in use, and the square is shown in all 

 its positions from start to finish in the formation 

 of the brace. The gauge line marked 0000 -is 

 the line from which the marks 12 and 12 are 

 supposed to measure, and this when squared Qver 

 as shown leaves a butt, or "heel of the brare," 

 which is to rest on a shoulder "boxed" in both 

 beam and post. The dotted lines on the ends of 

 the brace show the tenons for which mortises 

 are made in both post and girt or beam. It must 

 be understood, of course, that this operation is 

 only performed once for each kind of brace, and 

 that on a pattern made of some kindly wood,. 

 Mich as pine, cedar or whitewood. For the pat-
