Dome drive nightmare

Using a car screen wiper motor, that I totally wrecked, I tried to make a dome drive system. I used a rubber wheel and a wooden frame. I hooked it on the rods that are supporting the frame, attached a spring to it and made sure that it did make good contact with the rockler bearing. It worked! Unfortunately the axle of the motor was threaded ( like a screw ) and therefore the wheel was not entirely vertical. SO I took the assy out and wil try something else.

What did work was the RC unit I took from a RC car. It has a transmitter and receiver, 12V batterypack and 2 relais. I will be using this for the feet driving, to play with, untill I will buy more robust and professional equipment.

Later!

Continuing story of the legs



I managed to get hold of 0.5 en 1 mm polystyrene. Now I can finish the legs. I'll use the 1 mm for the ankles and then, after sanding and smoothing the wooden legs a bit, I will use the 0,5 mm styrene to cover the wood.

Dome painted



Well, I painted the acryllic dome. That was quite a job. Being plastic, I had to use special primer first. Then I was to quick with spraying the colors. The grey color went ok, but the blue started to blend in with the primer. So I primed it again, let it rest for a day and then sprayed the blue, over and over again. I'm quite happy with the result. Hack, this is a trial project anyway!
