Artificial Grindstones

Washed silicious sand, 3 parts; shellac, 1 part; melt, and form it into the proper shape while warm.

The fineness of the sand must depend on the work the stone is intended for. Powdered emery may be substituted for sand. The same composition is formed upon pieces of wood, for the purpose of sharpening knives, and cutting stones, shells, &c. 6268. To Make an Emery Wheel for Grinding Tools. Provide a solid wheel, made of pine, or any other soft wood, and of the size required for the purpose. Turn the wheel true, and then turn rounds or hollows in its face, to suit the tools you wish to grind, gouges, rounds, &c. Then prepare some best glue, and, using it hot and thin, put it on the face of the wheel with a brush. The first coat of glue should be a light one, and when it is dry a second one should be applied, and, as quickly as possible, as much emery should be sifted upon the wet surface as the glue will hold.

When this is dry another coat of glue and emery should be applied in the same way. This will make a wheel that will last for months, and grind faster than anything else. No. O emery is best for this purpose. (See last receipt.)
