Single dish setup

I started with a single dish to get an idea of the energy it would produce. As you can see, it can ignite a piece of wood, and should cook a hotdog if you can hold it in the focal point. I started with a square piece of an old cabinet top for the dish base, but any piece of wood will work.I mounted two non swiveling wheels on the wooden base, and cut a notch for a gearmotor with drive gear, to act as the horizontal tracker drive.
A piece of 2X4 was trimmed to fit loosely in the dish mount after the steel tube clamp was removed, and added a 1/4" through bolt to serve as the vertical axis pivot.
A second gearmotor was mounted on a sheet metal bracket, on the side of the 2X4 upright. A steel rod was drilled with a 1/4" hole on one end, and the motor shaft diameter hole from the other, with two set screw holes to keep it all together. A brass block was drilled with a 1/4" hole to act as a pivot and a second threaded 1/4-20 hole at right angles to act as a lead screw nut. While this all worked pretty well, I was not satisfied with the power output so I moved on to the quad dish.
