Solid Kmery Wheels ore now almost in universal use for the purpose of gulletting and gumming saws. Statistics show from 25,000 to30,000saw-m illsIn 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 SI 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 Fernery Wheels was so uncertain, and the demand so fickle, that storekeepers could not afford to carry them In stock. Now, however, Saw Gumming Wheels have become as staple an article as Files, and every dealer In saws, Hardware and Mill Supplies can aflbrd to carry a few dozen standard sizes In stock. Large dealers order 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-eiglhs of all in use are beveled. Tne principal sizes are: 8x2 8x1 8x| J in. hole. 10x1 10\i lOxS loxi J in. hole. _ Holes, J, I and 1 inch. Probably more wheels 12xs, 12xJ and 12xj are used than all the other sizes together. Saw Gumming Wheels are used, however, of all sizes up to 24x1}. 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 touc
