These pointsrequire frequent-ly to be trimmed,because from re-peated sharpen-ing the wedge-shaped plane-iron graduallysinks deeper inthe socket, caus-ing the wedge to do the same. Should the sole of the plane become warped, or uneven naning thethrough wear, it must be carefully planed. It follows from construction of the socket that the opening m front ot tne piece 1/iron, after repeated planing, becomes too large. It is usual °^^-to remedy this by inserting in front of the iron a piece ofvery hard wood, , ebony, beech, or boxwood (see Fig. 56).Brass is also used for this purpose. New planes are also G. ^ d Fig. 56. Portion of Plane. Socket, i.

Putting in the Plane-Iron or Setting* the Plane. The cover is screwed tightly on the iron, with its sharpedge at the proper distance from the edge of the iron, whichis then laid in the socket, just deep enough to allow its edgeto lie in the same plane as the surface of the sole. Thewedge is then put in, and secured by a couple of light blowsfrom the hammer. The plane is then taken in the left hand,with the thumb resting on the wedge in the socket. Thesole is turned upwards, and the iron is carefully driven in alittle more, so that its edge shows just as much beyond theplane of the
