Open a box of safety matches and measure the diameter of the end of the box part that holds the matches. The usual measurement of the end of the inside box is ⅝ by 1⅜ inches.
Cut a strip of tin ⅝ of an inch wide and 2⅛ inches long. Make a mark ½ inch from each end of the strip and bend the tin at right angles at each end, using each mark for the bend.
The strip should then appear as shown in Fig. 29, A. Solder this strip in the center of the small can as shown in [Fig. 29], B, but make sure that the cover of the match box will slide over it before soldering it fast.
Cut two pieces of tin 1½ inches wide and 2½ inches in length. See that they are cut perfectly square. Mark off a line ¼ inch in from one end of each piece and turn the tin at right angles from this mark to the edge.
Fig. 30.
The corners at the opposite ends of each piece should be rounded off by cutting with the shears as shown in [Fig. 29], C. Round over the edges with some fine emery cloth. Place the cover of the match box in position over the strip of tin soldered to the can in the center of the tray. Place the two pieces of tin against the two opposite sides of the match box as shown in [Fig. 29]. Then move them slightly away from the box and mark the position of the flanged ends where they rest on the can, remove the box cover and solder these pieces of tin in place. Be sure to solder these pieces in such a way that the match box cover will slip between them easily and fit over the bent strip of tin at the bottom. The ash tray and match box holder will then be completed and ready for the lye bath and painting.
An extra coat of some high-grade spar varnish should be given the ash trays to prevent the hot ashes from burning the paint. This varnish should only be applied after the first coat or coats of paint are thoroughly dry.
The height of the trays at the edge may be altered to suit and also the height and shape of the can soldered to the center of the tray. The measurements are merely given for convenience in working out these first problems. Every effort should be made to think out problems of your own, taking the suggestions from the shapes of the cans themselves. Thus a square can may be soldered in the center of the tray, and small semi-cylindrical troughs of tin may be soldered to the rim of the tray to hold lighted cigars and cigarettes.
