Llo PETERBOROUGH, OUNTT. EMERY WHEELS FOR SAW GUMMING!. Solid Emery Wheels are now almost iu universal use for the purpose of gullelling and gumming saws. Statistics show from 25,000 to80,000BBW-mlllBID the United States. Many of these run only a single saw each. A one-saw mill would use one or two Wheels a year, costing *3 to $1 each, and when such small mills order single Emery Wheels from the factory, the express charges often equal the cost of the wheel. There was a time when the quality of Emery Wheels was so uncertain, and the demand so tickle, that storekeepers could not afford to carry them in stock. Now, however, Saw Gumming Wheels have become as staple an article as Files, ami every dealer In saws, Hardware and Mill Supplies can afford to carry a few dozen standard sizes in stock, Large dealors ordor stocks of $500 to $750 worth at a time. Saw Gumming Wheels are used with the edge (or face) square, round or beveled. Probably seven-eigths of all in use are beveled. Tne principal sizes are: . Bxi 8x1 8xJ i in. hole.

Saw Gumming Wheels are used, however, of all sizes up to24x1}. The most frequent complaint is that Emery Wheels harden the saw so that a file won't touch It. The an
