Hey guys, just seeing this thread. I made my own by mounting aluminum pool ladder mounts to the bottom of a piece of plywood and sit that on my lighting tripods. The pool ladder mounts have a set screw, and are slightly larger than the pole from my ADJ lighting tripods (with the t bar removed.) I've used this to hold my Pluto IIs.
I got the aluminum pool ladder mounts via Amazon. I am slightly worried that they're cast aluminum and will crack in half or something, but so far I've had no issues. Most of the weight is vertical against the top of the lighting tripod so the force on the walls of the mount are mostly stabilization.
Bradfo had some really nice looking similar things @ SELEM made of solid aluminum I think?
An earlier model I made used two C Clamps mounted to the laminated wood used for shelving. I used this to hold a pair of stacked video projectors on the same American DJ tripod for outdoor side-of-building MarioKart.
Lots of good ideas guys -
Appreciate all the feedback!
