Miscellaneous Tools

Figure 67 shows the box and tap for cutting wood screws. Such screws are best made from box or hornbeam, although beech can be used if the threads are coarse enough. The screw itself is turned up to the required diameter, 1 in (25 mm), 3/4in (19 mm) etc., the end chamfered for entry, and the box or die turned round it in the usual manner to cut the threads. The hole for the tap is then bored to the exact diameter of the circle always marked on the side of the box, and the taper tap fed in.
