remembered that most barrels taper, hence the inside of band must have a slight taper also. Shelby tubing and other §oft steels will stand considerable stretching, therefore we select our tubing with inside diameter slightly less than the barrel diameter at the point band is to fit. If possible, select tubing with an inside diameter about the same as the barrel thickness some two or three inches ahead of the final location of band.
First we will make a simple inside band with stud for a swivel screw to go through the forearm; details of this band are shown in Figure 141. Cut a piece of tubing of the proper size about 5/8 inch long; the wall should be from 1/4 to 3/8 inch thick. Hold the piece in a large vise, and with a rather coarse cut hacksaw, lop off excess metal as shown in Figure 142. Now work off the corners on emery grinder, or with a coarse cut bastard file, until the band portion is about 1/16 inch thick. Shape up the base or stud portion so as to keep die sides parallel, and shape up fillets where the base joins the band with a small rattail file. Hold the band in vise so that the jaws press against the edges, not on the sides.
The next step is to locate th<? point for the screw hole in center of ba<?e, center punch it, and drill and tap the hole for the swivel
will set at an awkward angle. Now we are ready to fit the band to barrel and form the taper. It may be fitted right on the barrel, or if you have an old damaged barrel of the same size and taper, use it instead. Save all old discarded barrels, as they make good forming bars for bands. Another way is to have a number of short arbors turned up with various tapers likely to be needed, and keep them for this work. This is really unnecessary, however, as the band can be fitted right on the barrel without hurting the barrel if you use reasonable care. The only damage possible is to the finish, and if a band is being fitted to a new barrel that is not to be reblued it is sometimes difficult to prevent scarring it slightly.
If the band is very rough inside—and most Shelby tubing has slight marks and ridges left by the drawing process—smooth it out
