PROJECTS IN LACING BELTS

302. Single - Cross Lacing; Two Rows of Holes 

 Punched on Each End. 



Note: The instructions given below are for a 6" belt. It 

 will be noted by referring to Fig. 334 that the lacings on the 

 pulley side of the belt do not lap one on another. The holes 

 being staggered, cause the lacings to lie singly, which is a de- 

 cided advantage in overcoming noise in running, and wear. 



PULLEY 



FIG. 334. Single-cross lacing; two rows of holes. 



Working Instructions: Punch two rows of holes with a belt 

 punch parallel to the end of the belt. The diameter 

 should be about two-thirds the size of the lace to be 

 used. The first row is placed about 3/4 " from the end of 

 the belt, and the second row about 1-1/2" from the end. 

 In case the belt is old, these distances are increased 

 slightly. The holes are from 3/4" to 1" apart with one- 

 half this distance separating the end holes from the 

 edges of the belt. Determine these outside distances first 

 and then divide up the intervening space so that the 

 distances between points will be as nearly as possible 

 3/4" (B, Fig. 333). Beginning with the end points on 

 the first row from the end of the belt, punch a hole at 

 every other point. Only one-half the number of holes
