Some pictures of how the actuator connects to the rack.
If someone wants to build one, I think it was fairly easy to do because all I did is scale down the dimensions from the full size unit Not all the dimensions are in the plan that I linked to in my first post, but probably enough to figure it out. I now have it set up with a small 12v charge controller so I will just let it sit there and charge batteries all day.
