Solid Emery Wheels are now almost in universal use for the purpose of gulletting and gumming saws, *how from 25,000 to 30,000 saw-mills in the United States. Many of these run only a single saw each. A one-saw mill would use one or two wheels a year, casting S3 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 souncertain, an^*dema°^ fickle, that storekeepers could not afford to carry them In stock. Now, however, Saw Gumming \\ heels have become a. staple an article as Files, 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 $500 to $750 worth at a time. Saw Gumming Wheels are used with the edge (or Me) square, round or beveled. Probably seven-elgths of all In use are beveled. Tne principal sizes are: 8x4 8x1 Sxi J in. hole. 10x4 10x1 10x5 10x5 j in. hole. Holes, f, | and 1 inch. Probably more wheels 12xj, 1*4 and 12x| are used than all the other sizes together. Saw Gumming VMMM used, however o fal?^eB up toMxiJ. The most frequent complaint is that Emery Wheels harden the saw so that a file won't touch It Thlanswer U that youM want a file to touch it.
