W/VWrtH*l/ KEEPING CIRCULAR SAW COOL. In reply to " English Timber " our advice as to the best way to keep your saw cool is, keep it in good order, have a proper shaped tooth for the work to be performed, have the saw care- fully packed, do not crowd the feed, and open out the cut immediately it passes the saw. We are aware that with some kinds of wood it is somewhat difficult to keep the plate cool. With many saw benches we have seen the saw guide is continued too far past the front of the sa*ff and thus crowds and heats the plate through not allowing sufficient room for the wood to open out as it is cut. If the fence extends, â¢ay, 4 in. beyond the roots of the teeth it should be enough. Heat is often communicated to a saw through the saw spindle from the bearings being out of order or screwed up too tight. The â aw should not fit too tightly on the spindle or bind the steady pin. A saw when properly hung should in the horizontal line incline very â lightly towards the timber, so that the teeth at the back of the saw may rise without tearing or scoring the wood. If the driving pulleys are of too small diameter, or the belts too narrow or run at too short centres, they will cause the bearings to heat, and this is often conveyed through the saw spindle to the saw. There is an American patent in force for keeping circu- lar saws cool when runniug; it consists in making the saw spindle hollow, and taking a stream of water through it, which is allowed to escape at the collar on both sides of the saw while in motion, the contrifugal force distribu- ting it equally o
