Rehang Your Grindstone.

The periphery of every grindstone on which edge tools are ground should run as true as the dressed surface of a millstone, as it is impracticable to grind a tool correctly on a stone that revolves with an uneven” motion. If the periphery of a stone varies half an inch in each revolution, the most expeditious way to put it in order ie to loosen the wedges with which it is keyed to the journal and rehang it. Then secure the bearings of the journal so that they cannot be easily lifted out of the boxes and turn the periphery off true and smooth. Let a firm rest be fixed close to the periphery before attempting to turn off the prominent portions. The rest must be solid, with the surface close to the stone, so that when the turning instrument coipes in contact with tbe stone it will remove a thin chip without springing away from the stone. Stone turners always employ for a turning tool the end of a bar of very soft- iron; drawn out to a point and turned up at the end for gouging. A. piece of soft mod is far more effective than steel. OafVthe best for turning off a smaflnandstoqe consists of a thirty-penny cut nail driven firmly about two inches into the eud of a hard stick of timber to facilitate holding the nail. Then, with the end of the nail held like a turner’s gouge, proceed to turn off the grindstone. jLet grindstones be shaded always from the Summer’s sun.—W. Y. Herald.
