TURNING OVER EDGES ON ROUND TRAYS—USING THE FORMING MALLET—MAKING AN ASH TRAY AND MATCH BOX HOLDER
Various round trays may be made from tin cans. These are very simple to make and are very attractive and convenient for ash trays, bottle casters and the like. A match box holder may be soldered to the center of the tray and any smoker will appreciate this. These simple trays have proved to be one of the most popular problems for certain wounded soldiers in an American base hospital in France.
=Turning Over Edges on Round Trays.=—Select a rather large can to cut down for a tray. A can from 4 to 6 inches in diameter is best with which to start tray making. This can should be round, as the square cans are very difficult, if not impossible, to handle when turning over an edge.
Set the dividers to 1¼ inches and scribe a line parallel to the bottom of the can. Cut the can down and be careful to cut it off as straight as possible at the scribed line.
Place a square maple block in the vise; the same maple block you have used for turning the edges of the handle for the biscuit cutter. Be sure that the edges of the block are square and sharp.
Set the dividers to ¼ inch, rest one leg of the dividers on the rim of the tray and scribe a line around the inside, ¼ inch down from the edge, as indicated in Fig. 23.
Rest the edge of the tray on the edge of the wooden block so that the line scribed ¼ inch down from the edge rests directly over the edge of the block as indicated in Fig. 24 a.
Tilt the tray back on the block until the edge is raised about ⅟₁₆ inch up from the surface of the block, the line still resting directly over the edge of the block.
=Using the Forming Mallet.=—Take up the special forming mallet and use the rounded end to start hammering the tin down to the block, still keeping the tray tilted as indicated in Fig. 24 _b_. Turn the tray around as you hammer so that the tray is slightly flanged out by the mallet blows as you turn it around on the block.
