To enable the wheels to turn (fingers crossed) I have to make a lot of different plywood components very precisely to build the all-wooden drive system. I don't have access to a CNC machine so it's all got to be done by hand, old school, on the bench, the way it should be...

I have also refined the plywood and MDF seat which I blogged about the other day. I took a plaster cast of James's bot bot and whittled away until every curve and pimple was fully accomodated... I don't want him whinging come the big day!
