A grindstone mounted in a dwarf iron stand is shown by Fig. 434; this is one of the cheapest forms for the worker’s use, but. of course, one mounted on a high iron or wooden stand with treadle, as in Fig. 435 or Fig. 436, is much more convenient. The home-worker who does not care to buy an expensively mounted stone may construct a strong frame on which to mount a grindstone of 4-in. by 3-in. stuff, with the legs well spread out and braced together about 6 in. from the ground. It is sometimes a great advantage when grinding a thick heavy iron or axe to be able to stand higher on one foot. Under the stone should be a box to hold water, in which the stone will be partly immersed. Some prefer a can fixed above to allow the water to drip on the stone. Too much has the disadvantage of splashing on the ground and over the legs and boots of the grinder. Others dislike the box below the stone, as the water always left in the box tends to soften that part of the stone which is immersed in it. This can be avoided by having the box loose and letting the two end pieces run up longer than the sides. Let these pieces be of the same width at the top as the rails in the ends of frame, and with a pair of butt hinges hang one end to the frame. Nail firmly to the other end of the box a leather strap, and punch half a dozen holes in it about 1 in. apart, the end with the holes projecting above the box, and screw a stout 2-in. screw centrally into the other end rail. By this means the box with the water can be raised whilst grinding, and, when finished with, it can be dropped down a couple of holes so as to clear the stone. Thus all the advantages of a box, without its drawbacks, can be secured. It can also be easily dropped right down to the ground for cleaning out, or in the event of any small tool falling into the box, as sometimes happens. Always grind wide tools near the edges, which will help to keep the stone slightly rounding on the face.
