I am sure you have all heard this before, but does anybody know how to build a swivelling teeter totter like the one on air supply?

Picture a normal teeter totter, then tilt the pivot log up at a ~30 deg. angle. Then tilt the riding platform so it is level once again. Does that make sense?

The one on Air Supply rotates about 25-30 degrees as it moves. It must have a pivot as well as a fulcrum. There is a log covered with sheet metal as a bearing and guide for that teeter totter on the down side. It's been a while since I've by that trail. I don't ride that stuff ever, but I have checked it out on foot.

Its easy. Someone else already expalined how to do it, but I'll try again. Think of a turnstyle in a subway or staduim. The kind with three arms. There is on pivot. Because the pivot is at an angle, the arms move down and to the side as you wlak through. Same principle as your rotating TT. If you want to build a model, try sticking paper clips into a large eraser. Seriously. It will help you visualize it.
