One jaw is nil off a widtli of a band above the shoulder and the oilier is fitted to the groove eul in the rod thai is to be brazed to the pliers to accommodate the bands. When the two are brazed together, the difference in thickness of the I ape red jaw and the rod is filled with solder. The excess solder is removed and (lie remainder is smoothed and shaped with a file. For a No. waterfowl band, the rod should be about ,',,-inch in diameter, and approximately M) inches long. Cold-rolled steed should be used. A |-inch bolt 7 inches long with a right- angle bend is welded to the plier handle near the pivot. The band spreader can then be attached to some support. A convenient support can be made by welding a $ inch iron pipe nipple to a lighl weight steel post 4 feet long. The posl can be pushed into the earth to the desired depth and the boll on the band spreader slipped into place. \ multiple mouid can be made by welding to the post a cross-piece to which have been brazed three or four |-inch pipe Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
