done this, "face up' the other side of the emery wheel, copper it and project the center line across it with the centering square; from this measure off and rule in the side lines of stud, as you did on the other side. Now set the piece in the vise, and with the hacksaw lop off excess metal, as shown by dotted lines in D, Figure 36. Now slide the piece down in the vise so that just enough metal projects below the upper edge of jaws, to give the depth of fillet wanted where the stud joins the band, and with a rattail file of the right size, file down in this fillet until the file touches the vise jaws. Be careful not to make this fillet cut run through the line
of the side of the stud—bear pressure to right or left as required, or shift the position of the piece in the vise slightly if necessary.
Cut the fillet on the other side of stud in exactly the same manner; then reset the work in the vise so that the side lines just meet the edge of vise jaws, and file down to these lines. Thus the stud is quickly roughed to final shape, needing only smoothing up with a finer file, and slight rounding of the sharp edges.
The band is now clamped edgewise in the vise and the sharp corners of the saw cuts roughed off with a double cut flat bastard file, until the band portion is about 1/16 inch thick. For this work use the file in any direction that is most convenient—around the band, or across it. If you have an emery wheel, some filing may be saved by roughing off the saw cuts on the wheel, the band being held in the fingers on the tool rest of die grinder, and turned about as required. The band is now ready to fit and finish as described in Chapter 24.
When making small parts to replace broken action parts, great care is neccssary in the filing to shape the new parts exactly like the old. A hammer, or trigger, for example, must be accurately shaped or it will not work with the other parts in the action. The best way to accomplish this is to first work down the stock for the new part to nearly the correct thickness; tin one side thinly with soft solder; tin the pieces of the broken part, lay them together in correct position on the new piece of stock, and sweat them on. Then grind or file the metal down to the exact outline of the old part. If the part has a hole through it for a pin or screw, this should be drilled through the hole in old part before shaping up.
When there is such a hole, and the shape of the part is not com
