Material: For bowl, copper 123⁄4 × 6 ins., No. 20. For base, copper 41⁄2 × 41⁄2 ins., No. 20. For handles, 2 pieces or 3 pieces of copper 8 × 1 in., No. 20. Solder.
Tools: Combination stake, anvil stake, shears, drill press, drills, rivets, shaping hammer.
Directions—Bowl: Bend the 123⁄4 × 6-in. piece of copper into a cylinder over the combination stake. The two edges should just meet, and fit perfectly along the line. Scrape inside and outside the joint. Wash with borax, bind with binding wire, and solder. Be careful to heat it all over the fire till the solder runs freely and fills every part of the joint. Cool off, then round it up again in the stake, filing off the surplus silver solder inside and outside. Hammer the joint down till flat and true. If carefully done this will show a thin even line of silver.
Base: 41⁄2 × 41⁄2 ins. Cut a 41⁄2-in. disc. Place the cylinder just made on the disc, allowing the surplus to extend out evenly all around. Draw with a pencil the outline of the cylinder on the disc. The rim must be turned up at right angles to the circle so that it fits exactly over the cylinder. To do this, place the edge of the disc on the sharp edge of the anvil stake, driving the edge over. Anneal and repeat until the sides are at right angles to the base. File off the top perfectly even, rounding out the edges. This makes a finish and border to the base. Push the cylinder into the bottom. Prepare, as usual, for soldering. Be careful to put bits of solder both around the edge of the turned up flange, and on the inside bottom edge. Heat and finish.
Handles: Copper pieces, 8 × 1 in. Cut a tapered slip off each side of the handle pieces, until the large end is one inch wide and the small end 3⁄4 in. With dividers draw 1⁄8-in. line parallel to those sides. Bend each side back on this line. Shape the handle (see [design]) over the combination stake, using the fingers or mallet to do so. The top of the handles should fit up close against the top of the cylinder and should extend down about 2⁄3 of the depth of the bowl. The ends may be rounded off nicely with the shears, and filed. A 1⁄8-in. hole must now be drilled in each side. Place the handle in the proper position on the bowl. Mark the holes and drill them where the marks are made. Place rivets and rivet the handles on. A touch of soft solder will help keep these handles in place and at the same time will prevent any possible chance for leakage through rivet holes, for where you have rivets you are apt to have a leak. Clean, polish, and finish.
COPPER BELT BUCKLE
Buckles may be made of copper, silver, or brass, and the process of making them is very simple. This design shows a buckle for a man or a boy.
Material: Copper (or brass or silver) 5⁄16 in. square × 8 ins. long for the frame of the belt. One piece 1⁄8-in. round rod × 13⁄4 in. long for the cross piece. One piece 3⁄16-in. square × 2 in. long (pin). Borax and solder.
Tools: Mallet, file, pliers, combination stake, and vise.
