Bent-Iron Pipe Rack
Design of a Rack
Strips of soft iron, 1/4 or 3/16 in. in width and 1/32 in. thick, are used in making the pipe rack shown in Fig. 1. This material can be obtained from any local hardware dealer who carries bar iron in stock.
Draw a full-size sketch of the design on paper, then run a string over each part, which, when straightened out, will give the length. The scrolls are bent with a pair of round-nose pliers. These, with a pair of flat-nose pliers, are all the tools necessary. The part for holding the pipes is shown in Fig. 2. The end elevation, at E and F, shows how the rack is fastened to the main frame of the rack.

To Clean Silver
A good method to clean silver of any kind is to place the articles in an aluminum vessel and add a few pieces of zinc. Hot water is added and the silver boiled until clean. It is best to use soft water. The tarnish is removed by the electrolytic action of the zinc on the aluminum and the silver, and the latter will take on a bright luster. This method of cleaning will not injure oxidized or black silver, nor that which is partly oxidized.
