Taking a break from the bucket truck, I finally got the two 18" dish movers mounted on the big Solar furnace.
The vertical axis was easy, I used the old actuator arm on top, and welded up a simple bracket on the bottom.
The actuators have adjustable stops, which I adjusted so the travel was full range without hitting the stops. The horizontal axis was a bit more work, as the VW wheel, and stiffening webs only gave a narrow path for the actuator shaft to pass by. I wanted as near to 180 degrees of rotation as possible, so an offset bracket was made for the dish side so the actuator would clear the mounting shaft. It is a bit heavily loaded when at the two extremes of travel,because of steep actuation angle, but is smooth and strong every where else.Next the water proof box for the electronics.
