I have begun to put the twists into the new carving. It is no easy matter trying to plan how much twist should go into each section and which way it should turn. I decided that where the parts cross each other they should be exactly diagonal so as to present the best access. At the top and bottom the sections should be square and parallel to the floor to allow best contact for the base pin. Having decided these criteria the rest fell into place. The other news is that I have badly damaged the telehandler. The main hydraulic ram wobbled itself free and then broke from its end. I then, unaware of the problem but wondering why the boom was not lifting pushed the ram end straight into the gearbox. The power of the ram is so huge that it smashed its way through the gearbox housing and bent all the surrounding metal. What a fool I feel not to notice the pin wobbling free.
