Setting a Saiu. — In this operation every alternate tooth is slightly 

 bent along the full length of the saw, which is then reversed in the 

 clamp and the remaining straight teeth are dealt with in the same 

 way as the others. In setting a saw an operator should be very careful 

 to see that the same amount of " set " is put on each tooth, for if one 

 tooth is set more than another it will make the saw jump, and a rough, 

 jagged cut in the timber results. In setting the teeth it is necessary to 

 bend them just enough to allow the blade to move forward and back- 

 ward freely, otherwise the set will be too wide, and will cause the cutting 

 of unnecessary timber, and mean a waste of time.

There are many kinds of adjustable saw sets on the market, which 

 can be purchased at from 3s. to 4s. 6d. For different timbers varying 

 sets are necessary, green timber requiring more than dry. The adjust- 

 able set is therefore indispensable, as by its use the adjusting may be 

 quickly performed and the set made perfectly regular. 



In setting a crosscut, each tooth is treated as in the hand saw, but 

 with an ordinary set, with gauge unattached. The gauge is & flat 

 piece of metal with a small slot cut out of one corner, as shown in
