Small sheet of hardboard, any off cuts will do.
A fretsaw (hand or powered)
Leadfree pewter, which you can buy online.
Blowtorch, or small camping stove.
A clip for the hairslide or a piece of dowel about pencil sized.
Solder and soldering iron or pencil torch.
Polishing wheel or dremmel.
Step 2: Making the hardboard mould
Place the first board onto the next board and draw around the oval shape, next draw the waves within this oval shape onto the board, cut the waves out with the fretsaw and lightly sandpaper. Thin down the waves with sandpaper so that they are about 2mm thick, use wood glue to attach the wave shapes to a piece of board as in the photo. So what you have is a three part mould, an oval shape that drops over the wave shape and then a flat back. Cut a v shape in the top of the oval as in the photo and file a groove in the back board with a round file, this is for pouring pewter into when the mould is put together. Make sure the smooth side of the Hardboard face each other not the rough side.
