SMALL SAWMILLS, THEIR EQUIPMENT, ETC. Si 



A properly adjusted set of inserted teeth should be used until worn 

 out. Sharpen them as often as necessary by filing on their underside 

 with an inserted tooth file, i. e., a mill file with one round edge. After 

 being sharpened several times they should be relieved on the sides. 

 Should a shank become straight or compressed, because of the saw 

 being run on iron, so that it will not hold the bit firmly, lay it on 

 the anvil and strike it with a hammer on the inner edge until it is 

 expanded sufficiently to hold the bit. Do not try the experiment of 

 bending each alternate tooth for the set. If there is any difficulty in 

 removing an old bit for the purpose of inserting a neAV one, never 

 hammer the wrench or the bit, but place a blunt cold chisel on the 

 heel of the shank, taking care it does not touch the saw plate, and 

 tap lightly with a hammer. This will start the bit and shank and 

 enable you to remove them easily with the wrench. It is important 

 that all the bits should be of equal length. In order to insure this, 

 get a small segment or section of an old plate that can be easily held 

 in a vise, and insert the bit that needs sharpening or swedging. 



For winter sawing use a sharp bevel bit with a narrower cutting 

 point than that used in summer. Saws over 48 inches in diameter, 

 when made thinner than 10 gauge, -^ scant, are not guaranteed. 



KEEP YOUR SAWS IN GOOD CONDITION. 



If through constant wear a saw becomes weak and limber, the 

 sockets become out of round, and the teeth show a tendency to break 

 or fall out, discard it at once, or send it back to the factory to be fixed 

 up. Saws which have passed through a fire can be repaired if any 

 life is left in the plate, but, of course, can not be made as good as new. 

 Shoulders of inserted-tooth saws that are broken off by running 

 against iron or stone can be welded on again, provided they are not 

 broken off too deep in the plate. If they are broken too deep 

 to weld, the saw can sometimes be renewed by inserting a piece 

 of steel and boring a new socket. The tendency to discard saws or 

 " scrap " them is very general in all mills, big and little, though in 

 many instances, particularly in small mills, the fault lies with the 

 sawyer and not with the saw. A little more attention to the proper 

 care of saws would remedy this evil. If an operator leaves his ma- 

 chinery unhoused, as many operators do, he creates a condition which 

 no amount of instruction can remedy. 



LOG DECK. 



Every mill should have a good solid log deck or skidway capable of 

 holding from 100 to 200 logs, and built with enough pitch to permit 

 the logs to roll down to the carriage by gravity. Logs should be 

 piled in the j^ard in such a way that they can be moved to the log deck 

 with the least possible expense and labor. This the small operator
