The 1/4″ wood has reappeared in the shop, so we were able to cut the block cover! I split the block cover into 3 sections to best make use of the 36″ x 24″ sheets of wood. Two of them were just ~20″ rectangles with alternating slot sections and hole sections for the screws; the other one was ~14″ and tapered out for the seat. It took an exciting 30 minutes to cut them all out on the laser cutter–woo! I was impressed by how flexible the wood was after taking it out of the laser cutter. Here’s a picture of the bent wood without very much force applied:
Then it was just a matter of screwing in the wood sections on the block and cutting out the hole for the steering mount in the middle. Like magic, each of the sections attached smoothly and accurately on the block. I think pictures are the way to go:
And there we go! The mechanical components are all in place, and now it’s just a matter of electronics. We hope to have a running kart by next week because it is CPW (Campus Preview Weekend) for prospective MIT students. Final stretch!
