Step 1: You Will Need:
- Plywood ( I used 18mm Marine-ply and glued 2 sheets together to make 36mm. The finished thickness of the rings should be 28mm) To make 1 set of rings, you will need 2 sheets of 50cm x 25cm which you will glue together.
- Woodglue, any reputable brand
- A Jigsaw - to cut out the circular shape of the rings. Mine was a deWalt, anything decent will do.
- A Drill and drill-bit to make a hole for the jigsaw to cut out the inside circle. Something bigger than the width of the jigsaw blade.
- Clamps or a method of clamping the sheets of plywood while the glue sets. I used some Irwin Quick-Grip clamps aswell as a bench-mounted Vice, and also some regular vice-grips. You could probably get away with putting some heavy weights on the plywood on the ground.
- An Orbital Sander or Angle Grinder with Sanding attachment. I used a Hitachi G12SR3 Grinder with a sanding head. It needs to be pretty powerful to sand the plywood quickly. it's 730W, 11,000 rpm and weighs 1.4kg. I wouldn't go much heavier as a lot of the sanding I did with one hand while holding the wood.
- A Compass for drawing circles
- A Ruler
- A Pencil and a Marker (that's 'sharpie' for you yanks)
