Step 1: Print out the shape and size you want to make. I laminate the shapes I use regularly to preserve them and make the templet sturdier.
Step 2: Trace out the shape onto a piece of wood. I use a 2 inch thick board.
Step 3: Next drill out as much material from the center as possible using a forstner bit. This will make the next step a lot easier and faster.
Step 4: Then using a router, hollow out the inside of your dish.
Step 5: Next cut out the shape using a bandsaw or jigsaw leaving about a ¼ inch thick rim on the dish.
Step 6: Sand to remove any rough spots.
Step 7: Put a finish on it and you're done:)
