LS FOR SAW GUMMING! Solid Emery Wheels are now almost In universal use for the purpose of gullcttlng and gumming snws. Statistics show from 2">,ikiii to 30,000 Baw-Bl Ills In the United States. Many of these ruu only a single saw each. A one-saw mill would use one or two wheels o year, costing $3 to $1 each, and when such small mills order single Kinery 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 Klles, and every dealer In saws, Hardware and Mill Supplies can afford to carry a few dozen standard sizes In stock. Large dealers order stocks of $">0U to $;>0 worth at a time. Saw Gumming Wheels are used with the edge (or face) square, round, or beveled. 1'robably Beven-elgths of all In use are beveled. Tne principal sizes are: g in. hole 10x l(l\ lOx KK •{ in. hole. 12x1 ^ 12xj} 12xA | 12x? 12x3 ) Holes, J, J and 1 inch. Probably more wheels 12xJ, 12xJ and 12zj are used than all tho other sizes together. Saw Gumming Wheels are used, however, of all sizes up to24xl}. The most frequent complaint is that Emery Wheels harden the saw so that a file won't touch It. The answer Is that, you don't want a file to touch It. An expert workman will shape and sharpen the teeth with au Emery Wheel, leaving the teeth case hardened, in which condition the saw will cut about 33} per cent, more lumber than a soft saw will. Those who want to use the file, however, have only to touch the saw light!!/ a second time (after going all over It once), and this second touch will cut through the case-hardened scale. A QU
