GRINDSTONE TRUING DEVICE. One of the. most disagreeable things to be done in a workshop is the truing of grindstones. It is, therefore, often the case that they are allowed to become quite out of shape and untrue, very much to the annoyance of the workman, who finds it almost impossible to grind his tools in a proper manner. The cut, Fig. 939, illustrates a device well adapted for truing and keeping the face of grind-stones constantly in good shape. This can be instantly applied to the face of the stone, working automatically, and without dust, keeping the face always in good shape without interfering with its constant use.

The prices are for Frame and Stone complete. We furnish a 12 inch pulley with all sizes. Will substitute any required size pulley, charging only the actual difference in price. Can also furnish Frame with 12 inch loose pulley additional, for $3.00 extra.
