Here is a photo.
I guess you can go look at all my photos I have.
Just a 3'' ploe with a 2'' flange bearing at the top to turn. Bought a Linear Actuator and put it on. The limit board was bad and as the post said but I got that going with some limits on the out side. Udsed wire around the house and a water tight bowl for a Jbox the breaker and so on. Mine just tracks East to West. The red Rock controller works great. Worth 3 times what I paid but don't give him any ideas. Planning to go bigger. All this is just learning and having fun.
Hope Some one good with math tells me what it takes to keep my tracker battery going. It's done fine for a week so for. When testing and setting up the actuator. I ran it in and out about 4 times and the battery was to low to run it.
