Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1912 edition. Excerpt: ...chisel or file and drilling a new hole or holes with an ordinary twist drill. If the saw--beyond the point to be softened--is wrapped in wet cloth or is inserted between larger pieces of cold metal, the saw may be heated red hot at the spot desired without injuring the temper elsewhere. Sometimes a broken blade will be too short to fit even an adjustable frame and under such circumstances two broken saws may be joined together by rivets or screws until the desired length is obtained. Of course this is merely a makeshift repair, but it will often prove of great value and convenience in time of emergency. Permanent repairs on broken band saws or hack saws may be made by brazing or by autogenous welding by oxo-acetylene methods, and while it is always advisable to have a broken saw brazed or welded by a specialist in this work yet band saws, large scroll saws, etc., can be brazed by any one with practice and proper tools. To braze a band saw the lap of the ends should be as short as possible and never more than one tooth. File the bevel so teeth will match at the lap and place enongh silver solder (which comes in ribbon form) to cover the joint, place the saw in a brazing clamp so that the joint or lap comes in the middle of the clamp opening, place the solder in the lap, sprinkle it with borax or some brazing flux and heat a pair of flat tongs white hot and clasp them firmly on the saw at the joint. By pressing the hot tongs together with another pair of tongs on the points of the hot jaws a greater pressure and better job will be accomplished. Hold the brazing tongs perfectly tight until they cool and turn black and then remove them, file the joint perfectly smooth and clean the solder out of the teeth. The materials required are merely the solder...show more
