If it's balanced it won't get away from you, the picture in the link I posted with my panel on it's side didn't have the pin installed.

 

on my frameturner the pipe that has the cross arm in it has a nut welded over a hole and a 1/2" bolt tightens down on the turning cross arm...and on both ends.. when you snug them down they WON'T turn... cheaper and easier than drilling all those holes
