I had an idea for a lampshade shade and knocked up a prototype. It's made from plywood. Making it was a good challenge. I had to make an upright jig that attached to a cross sled on the table saw. Basically spinning it a couple of degrees at a time using an indexing arm to evenly measure the gaps. Then cutting the slots for the upright ply sections to fit into. As ever, I learnt alot and I'm fairly pleased with the outcome.
