146. Clip Former.—[Fig. 133]. This and the two following tools should be made of 0.80 to 0.90 per cent carbon tool steel. A convenient size of material for the one shown is 1 × 1⁄2 inch. The portion forming the connecting loop must be flattened and forged to about 1⁄4 inch thick to provide a spring for retaining its shape. The ends should be forged to two different thicknesses. The 1⁄4-inch side is used in bending clips for banding two pieces of 1⁄8-inch material, and the 3⁄8-inch side for three pieces. When a different thickness of material is to be used, these ends should be made to correspond with it. The inner and outer edges of these ends should be made slightly rounding to prevent cutting the material from which the clips are made. Most of this light scroll work is made from stock with round edges, therefore it is not necessary to have the clips bent sharp and square.

The former should be so proportioned that it can be placed between the jaws of the vise, as shown in [Fig. 134]. Here the loop is resting on the box of the vise, which supports it and prevents it from falling out of position when the pressure of the vise is released. The ends of the clip former should extend above the jaws of the vise about 2 inches, so that the clips can be bent without striking the vise with the hammer. A view of these ends, with a piece of half-oval iron in position for bending, is shown at A, [Fig. 137]. One end of the clip material should be placed between the ends of the former, one half the width of the scroll stock, 3⁄16 of an inch if the stock is 3⁄8 inch wide. By tightening the jaws of the vise upon the sides of the former, the half-oval iron will be securely held, while it is being bent over with the hand hammer to the form indicated by the broken lines. The clip will then be ready for fastening the scrolls together.

147. Clip Holder.—[Fig. 135]. Stock 3⁄4 inch square is best suited for making this tool. The central portion forming the loop should be drawn and forged to about 1⁄4 inch thick, gradually increased to 1⁄2 inch where the shoulders are formed. The distance from these shoulders to the outside end of the loop should be less than the distance from the top of the vise jaws to the vise box. Then the tool will be supported entirely on these shoulders, as shown in [Fig. 136], and the tool may be placed near the ends of the vise jaws, which sometimes will prove to be quite an advantage. The length from the shoulders to the ends may be about 2 inches. These ends should be drawn tapering from the outer sides to about 1⁄2 inch square. On the inside a depression 3⁄16 inch deep should be formed so that the holder will fit over the bent end of a clip, as shown at B, [Fig. 137].
