SHARPENING is done on a very fine- grained stone, first wiped quite clean and given a few drops of thin oil. The strokes should be short, until skill is attained, and care be taken not to alter the angle between cutter and stone, and thereby produce a rounded, instead of a flat, bevel.
Adjusting the cutler in the plane to give the desired degree of cut should be a matter of test as well as of eye, since, if the cut is set too coarse, the wood may be damaged before the correct adjustment is arrived at. It is therefore advisable to sot fine at first, and increase the cut if it proves insufficient.
In the case of wooden planes, the plane is stood on its back ond with the top leaning towards the worker so that he may look down the sole; and cutter and wedge are pushed into place, the cutter just projecting. The wedge is given a tap with the hammer to secure the cutter.
If the cut is insufficient, the cutter is knocked in farther by light blows on the end. If too coarse, the plane is stood on end as before and the top of the front tapped. This will cause the iron to move inwards. Hard blows would loosen wedge and cutter; and they are needed only when the cutter is to be taken out for honing.
