Solar Panel Rotating Stand Contraption UPDATE 2

You could also just make a hoop under the front foot of the stand so it tilted back as it came through the middle and went back down again as it continued around. This would make it do the tilting thing by itself when you swivelled it.

Here is a photo showing the three hooped depression stop rails under the depression stops for each gun in this turret so you get the idea. Check down to the padre's right.
