Seth, a tripod like that would be an EXCELLENT version of an Obi Wan IV grenade neck. does it stay put or still pivot around?
If you look at the first pic on the link-- the top is the mount obviously, the silver bar goes down into a ball-socket, which it can pivot in any direction on. The big knob tightens to lock it into place. It could spin in place too if loosened ever so slightly.
On mine, I basically tightened the knob down, then pulled it off leaving just the nub it attaches to.
