Once you have your design make sure that you have contour lines of 0.3 mm inside your design, as the tool that you use to engrave it has a diameter of 0.5, so a radius of 0.25 and an extra 0.05 mm to protect against the tool wobbling. Once you are happy with your designs and have it in the right colours for your machine.

Step 2: Mill Your Design

Using a dremmel drill a well and runner, you will pour the pewter into the well, it should be slightly larger and should be to either side of where you want to pour the pewter into your design. You also need a riser for any air bubbles to escape.

Step 4: Cast Your Design

Attach another piece of modeling foam the same size to the face of your design, use three elastic bands to secure it, 2 around the sides and 1 around the top and bottom. Wearing safety goggles, an apron and heat protective gloves. Carefully place the mold under the spout and turn on the flow filling up the well first. once the pewter has filled up both the well and flown into the runner and both has risen to the top, remove the mold from the design and carefully set it to cool (add stuff about cool metal rubber bands.

Step 5: Remove Your Design From the Mould

Wait 15-20 minutes for the pewter to cool; after this time is up, remove the rubber bands and separate the pieces of foam to reveal your cast design on one side, remove the pewter with long nosed pliers and cut of your well and runner, and any pewter that might have risen into the riser.

Step 6: Sand Your Pewter Design

Sand your design using fine grain sand paper, for example wet or dry. If you use 3D printing gloves you can sand all of the delicate parts and get a smooth finish without accidentally sanding your fingers. Be sure to do this far away from any computers and the metal shavings can mess with the circuits.

Step 7: Bend Your Ring

Bend your ring around a dowel about the the size of your finger, mine had a 6cm circumference. To bend it place the head of your ring, and the dowel in the table clamp then carefully bend it round the dowel using a square pole, rotating the piece until you have bent the ring into its desired shape.
