mitre box

Provide yourself with a good saw, a hammer, a square, and a mitre-box.

The camber facilitates cutting to the bottom in mitre-box work without sawing into the bed piece of the box.

Hand sawing is generally not exact enough to produce angles of sufficient accuracy even when an ordinary mitre box is used.

Fig. 182 shows the shapes possible on a 45-degree mitre box.

An iron mitre-box is useful but rather expensive, and you can get along with the wooden one described further on.
