CHAPTER XXI

SOME MISTAKES, AND A LITTLE ADVICE IN CARPENTRY

In the mechanical arts, workers are as likely to learn from the mistakes
committed as through correct information imparted. Advice, therefore,
might be considered superfluous. But there are certain things which are
easily remembered and may be borne in mind while engaged in turning out
any work.

This chapter is not given for the purpose of calling attention to all
the errors which are so common, but merely to point out a few which the
boy will commit as he tries to carry out his work for the first time.

One of the difficult things for any one to learn, in working with wood,
is to plane the edge of a board straight and square at the same time.
This is made doubly difficult if it is desired to plane it strictly to
dimensions.

Usually before the edge is straight it is down to the proper width
desired, and it is then too late to correct any error, because further
work will make it too narrow.

The whole difficulty is in the holding of the plane. It matters not how
rigidly it is held, and how carefully it is guarded to veer it toward
one side or the other, it will be found a most difficult task.

If the fore, or finishing, plane is used, and which is the proper tool
for the purpose, the impression seems to be, that to square up the edge
and make it cut off a thicker shaving on one side than on the other,
requires that the plane should be pressed down with force, so as to make
it dig in and cut a thicker shaving.

When this is resorted to the board is liable to get out of true from end
to end. A much better plan is to put the plane on the edge of the board
true and straight. If it is too high on the edge nearest you, bring the
plane over so the inside edge is flush with the inside edge of the
board.

Then use the fingers of the left hand as a gage to keep the plane from
running over.

Now, the weight of the plane in such a condition is sufficient to take
off a thicker shaving at the high edge, and this will be done without
any effort, and will enable you to concentrate your thoughts on keeping
the plane straight with the board.

The weight of the plane will make a thicker shaving on one side than on
the other, and correct inequalities, provided you do not attempt to
force the plane.

It requires an exceed
