Oilstones by their continuous use by students become hollow at the
center and must be trued up so that plane irons and chisels can be
sharpened properly on them. There are a number of methods that can be
employed to accomplish this; any of them, if tried, will give good
results:
1st Method. Take a piece of flagstone or any kind of stone that has a
flat surface, and on it place sharp sand and wet it with water. Take
the oilstone, and with a circular motion rub on the sand until a flat
surface is obtained. The sand should be kept moist during the operation.
2nd Method. Take a flat board and on it place a sheet of number one and
one half sand paper; moisten slightly and rub the oilstone on it until
the desired results are obtained. Emery cloth is also good.
3rd Method. We have obtained the best and quickest results from this
method, which is to have an iron plate finely corrugated and sprinkle
No. 30 or No. 40 emery on it; rub the oilstone over the plate,
sprinkling a little emery from time to time as the work advances. Use
the emery dry. An oilstone in very poor condition can be trued up by
this method in from three to five minutes.
A mixture to apply to a hard oilstone to make it “cut” when sharpening
a plane-iron or a chisel, is to take glycerine one part and alcohol
one part. This mixture will not become gummy, and an oilstone that is
sometimes considered worthless while using common oils, will be found
to give good satisfaction.
