WOODWORKERS' TOOLS AND EQUIPMENT 8 1 



nected to the driving shaft of the saw. The machine is mounted 

 on skids 13I feet long, shod with a Hght steel rail on which the 

 machine can be moved forward or backward for a working dis- 

 tance of 9I feet. This permits a number of cuts to be made at 

 each set-up of the machine. 



The saw, mounted, weighs about 1200 pounds. The sav/ can 

 cut at any angle up to 90 degrees and is run at a speed of 2500 

 linear feet per minute, cutting a kerf one-half inch wide. The 

 manufacturers claim that the saw will sever a 6-foot log in 

 four minutes. The largest log that can be cut is 8| feet in 

 diameter. 



The machine is dragged about and logs are rolled over by 

 means of a cable which is wound on a drum driven by the engine. 



Jacks are used to level the track when the machine is used 

 on uneven ground. 



An essential feature of every faller's and log-maker's equip- 

 ment is the wedge which is used to assist in directing the fall of 

 trees and to prevent the binding of the saw in the cut. They 

 are made either of metal or hardwood. Iron or steel wedges 

 may be made by the camp blacksmith, or purchased from dealers 

 in loggers' supplies at from 7 to 10 cents per pound.

The size and weight of metal wedges vary with the work for 

 which they are used, and the pattern is largely a matter of 

 individual choice. Felling wedges, especially when used in large
