Here you can see the basic body taking shape. It is just a basic cardboard shell roughly taped with masking tape. I use quite thin corrugated card which is very flexible. The corrugations allow it to bend nicely in one direction, in this case they go upwards so the shape curves towards the rear. I sometimes score the card if I want it to flex in more than one way.
Because the figure leans forward he kept falling over so I slit open the back and packed it with a lump of clay moulded to fit.
I've skipped a bit here to show the figure nearer its final incarnation with bits of plastic and cogs just poking out of his back. I had originally planned for him to be pushing some kind of cart with cables coming out but I like these slightly claw like walking sticks. They are just slotted into the arms so may change.
