TO MAKE A LETTER OPENER
This requires the same kind of material as the letter rack and the same operations, with the addition of riveting. After the stock is cut out, trimmed and trued up at the edges, an outline of the design is pasted on, as in the previous problem, and the design cut out. The top is then bent over and riveted with a copper tack, having shaped the head of the tack in the vise before inserting it. While the tack is being riveted the finished head should be protected by placing it on a lead block. Finally the edge should be filed to the shape shown in the cross section, and the whole cleaned and polished.
