solid at the bending point to keep the planks from pull- 

 ing apart. Drop short steel pins in the holes to form 

 a templet in the same way as in the use of a solid 

 timber bench. Always, if possible, bend all rods of 

 the same pattern at the same time in order to avoid 

 changing pins or blocks. 



There are on the market today several simple ma- 

 chines for bending these rods. From construction men 

 who have used both the verdict seems to be in favor of 

 a machine. 



Always tag each member for its proper position. 



Use a steam pipe with a coupling on the end to make 

 the short turns, when bending cold. The men should 

 be equipped with canvas gloves. Teach the men to 

 pull together on this work. Two men should be able 

 to make all the bends, but use three men on a crew, 

 one at each end of the bench and the third going back 

 and forth to help in bending. 



Bending Stirrup?. Bending shear stirrups or U-s 

 can either be done by hand on any of the benches de- 

 scribed, or by one of the machines now on the market. 

 For shearing use a compound lever shear, although 

 some construction men use hack saws. 



Hot Bending. Hot bending, sometimes necessary, 

 is not recommended by all engineers, and in some 

 cases is questionable. Use a small portable forge, and 

 support the rods with horses at the proper height 

 while being heated. 



Stirrups. When stirrups are wired or clipped to 

 the main bars, work on this inverted, that is, reverse 

 from the way it goes into the form. Attach stirrups 

 at proper spacing. Make the horses high enough so 

 that the men will not be compelled to stoop over. 

 WALL REINFORCEMENT. 



It is difficult to give any comprehensive discussion 

 of this question without going further into detail than 

 the occasion warrants. The main thing to accomplish,
