Method 3. When it is desirable to make the plate and handle support all in one piece, it may be done in any one of three ways. First. By allowing enough metal in the center of the plate to form the handle support as at [Figure 12]. Second. By allowing metal at the top of the plate to bend over handle as at [Figure 11]. Third. By allowing metal at the sides to be turned up at right angles to the plate to form the support as at [Figure 13]. In this case holes are drilled in the side pieces and a rivet is put through from one side to the other to hold the handle. For this one the handle must be either bent around the rivet or drilled to receive the rivet. In all three of these cases the plate is fastened to the door or drawer by nailing or riveting.

HINGES.

In a hinge, the joint is the important feature. The size of the hinge, the strength required, and the decoration must also receive attention. After these have been determined, a drawing should be made giving a development of the joint. Whatever the size of the hinge, the following principle in regard to the joint must be kept in mind. There must be alternating projections left on the inner ends of each leaf of the hinge to fit into one another so that the pin may pass through them and allow the hinge to swing. The method of making these projections is determined by the size of the hinge.

In hinges of any considerable size, the projections are left attached to the hinge proper; in allowing for them there will be an even number on one leaf and an odd number on the other. To obtain the strength desired, the width of the projections on one leaf should equal the width of the projections on the other leaf. This applies to any number of projections. Their length should be determined by the diameter of the joint, three times the diameter is the approximate length.

In making small hinges the projections may be bent into position by the use of the round nose plyers. In larger work the projection is fastened in the vise and beginning at the end is bent around the pin a little at a time using the raw-hide mallet to work it into shape.

For small joints or hinges, such as would be used on a match box, stamp box, bon-bon box, or ink pot, the joint should be made of small tubing as described on page [110]. This tubing is sawed into the required lengths and soldered to the leaves to be hinged. The parts to receive the joint are sometimes filed out.
