ROUND TRAY
Material: Piece of copper about 7 ins. square, No. 20 gauge. A hard wood block, 10 × 10 × 2 ins. thick. Tools: Carpenters' gouge chisel, dividers, steel punch, shears, round peg of wood, 6 ins. long and 1 in. in diameter.
Design: Take a large sheet of plain paper. Draw on it a 3-in. circle. Using the same centre, draw a 5-in. circle. This gives you the plan or top view of the tray. Below this view on the same sheet, draw the elevation, or edge view of the tray. You can make the tray as deep in the centre as you wish. Let's make this one 1⁄2 in. deep, that's a good proportion.
Hard wood peg
This is what we call a working drawing. If you are pleased with the design, you can go right on with the work, if not, you can change it to suit. You can see by the design that the tray is made by driving the centre of this square plate of copper down into a depression. In order to do this we must make a mould the exact size and shape of the tray centre. This is what the square hard wood block is used for.
