A forked projector mount

I'm thinking of building a hushbox for my projector- a hushbox is a box which helps isolate the noise of the projector from the room. I'll build it out of hardwood paneling and line it with some kind of sound absoroption- and have a filtered intake for the projector and perhaps redirect the output right into the attic.

For the cool factor, I want to motorize it.

Right now, I'm thinking of having a board on which to build my hushbox. The board will be suspended from the ceiling by 4 rods, sliding into a bushing mounted in the ceiling (like upside down motorcycle forks). In each rod, I'd attach some wire or webbing, which went up through the tube out the top, above the ceiling and attach to a shaft. I have an old garage door opener motor which I was considering using to drive the shaft.
