6271. How to Use a Grindstone

6271.    How to Use a Grindstone. Do not waste the stone by running it in water; but if you do, do not allow it to stand in water when not in use, as this will cause a soft place; it is much better to wet the stone by dropping water on it from a pot suspended above the stone, and stop off the water when not in use. Do not allow the stone to get out of order, but keep it perfectly round by use of gas pipe, or a hacker. Clean off all greasy tools before sharpening, as grease or oil destroys the grit. Observe: when you get a stone that suits your purpose, send a sample of the grit to the dealer to select by ; a half ounce sample is enough, and can be sent in a letter by mail.

6272. Soap in Place of Oil on Arkansas Stones

6272.    Soap in Place of Oil on Arkansas Stones. The employment of oil for the purpose of keeping Arkansas and other stones in proper condition for sharpening instruments is so general as to be almost, if not entirely, to the exclusion of every other substance. The tendency, however, to become gummy, and clog the surface of the stone after it has been on a short time, and the liability of soiling the fingers and imparting an unpleasant odor to them, make the use of oil objectionable. All this can be readily obviated, however, by using soap in place of oil, as follows:—Kub a piece of toilet soap and a little water over the surface of the stone until a thick lather is formed, and then allow this to dry. When occasion arises for putting an edge on a tool, a few drops of water will moisten the soap and place the stone in proper condition for use at once. This plan is one that has been successfully employed for years.

6274. To Face Oil Stones

6274.    To Face Oil Stones. Take a piece of iron with even or straight face (it ought to be planed); scatter a little emery or fine sand about as coarse as No. 11/2 sand paper on tho iron plate, add a little water and rub the face of the stone, renewing the emery or sand and water as requisite, finishing with an adition of water without emery or sand. This is the quickest and truest way, making the stone perfectly straight and occupying from 5 to 10 minutes time.
