IV.—USE OF TOOLS.

WE begin with the saws, of which you have two: cross-cut saw, and

splitting saw.

The use of a cross-cut saw, as the name implies, is to cut _across_

the grain or fibre of the wood: it is one of the most indispensable

tools we have. The teeth are finer and closer together than those of

the splitting saw, which, as the name describes, is intended to cut

_with_ the grain, usually lengthwise, of a piece of wood. Never try to

substitute one for the other, for you would injure your tools. When

you want to use a cross-cut saw, the saw should be held at an angle

of about forty-five degrees, and must also be held steadily without

swerving to the right or left; otherwise the teeth of the saw will

stick, and you cannot make a clean cut.

You will observe in looking at a saw that the teeth are _set_, as it is

called; every other point turning a little away to the right or left

of a straight line; the reason of this is, to make the cut wider than

the saw blade; otherwise after cutting in a little way the friction

would make the blade bind. Saws are, or should be, in proper condition

to use when they are bought; if not, or if by any accident the teeth

should get bent, you must have the saw _set_ without meddling with it

yourself.

A splitting saw is used differently from a cross-cut saw; it should

be held more nearly upright; the cutting is always done on the _down_

stroke. Never press the saw against the wood; the teeth will catch, and

the saw bend, and the wood won’t be cut if you add any weight to that

of the saw itself.

There is a certain amount of knack required in order to saw well, but

practise will improve even the most awkward workman. Always saw slowly

and easily, in a sort of regular time. Be sure the wood is held firmly

and doesn’t _hop_.
