TO MEND BROKEN SAWS 



Silver, 15 parts; copper, 2 parts. These should be 

 filed into powder and mixed. Now place your saw 

 level with the broken ends tight up against each other; 

 put a little of the mixture along the seam, and cover 

 with powdered charcoal; with a spirit lamp and a 

 blowpipe melt the mixture, then with the hammer set 

 the joint smooth. 



TO MEND A BAND SAW 



If a band saw is broken file the ends bevel, and lap 

 one end over the other far enough to take up one 

 tooth ; place the saw in such a position that the saw 

 will be straight when mended ; use silver, copper and 

 brass; file into a fine powder; place this over the joint 

 and cover with borax. Now heat two irons one inch 

 square, or a pair of heavy tongs, and place one on each 

 side of the joint, and when the powdered metal is 

 melted have a pair of tongs ready to take hold over the 

 joint with while it cools. File off and smooth the 

 sides, not leaving the blade any thicker than in other 

 places.
