The frog of the plane should be moved forward so that the throat in the front of the cutter is a mere slit.

In the ordinary plane it is necessary to remove the cutter in order to reset the frog, but in the Sargent plane and the Stanley "bed rock" plane, it can be set by a set-screw at the rear of the frog.

Next, the cap should be set so that the cutter projects but very little beyond it, or, in technical language, the cutter should be set "fine." A sliding cut, see p.

53, should be taken with the plane, and sometimes it may be necessary to move the plane nearly at right angles to the general direction of the grain.

By these means even refractory pieces of wood can be well smoothed.
