Greetings fellow DIYers. Thought I'd share my version of MonkeyMan's projector mount. My theater is themed after the Nautilus from Disney's 20,000 Leagues Under the Sea
so all of the equipment needs to fit in with the Jules Verne Steampunk theme.
The mount plates themselves are made from plexiglas, painted to look like tarnished brass. The countersunk brass screws around the edges of both plates are purely cosmetic. All of the iron pipes are actually plastic ABS, textured to look like cast iron.
The circular ceiling plate is lag bolted to a sub plate, which is in turn bolted to the ceiling joists. The bolts get covered with hollowed out rivet heads. The four holes in the center of the plate hold 3/8" T-Nuts to which the mount bolts.
Here's the top plate bolted in place, four long 3/8" bolts going up through the plate and compressing the riser tube, which is made from a short piece of 4" ABS pipe. The flange and nuts around the top of the riser are purely cosmetic. The cables run through the side pipes and down through the top plate, then are pulled back between the top and bottom plates.
A top view of the top plate, all built up out of 1/4" plexglas. Since my projector has lens shift capability I didn't make the mount able to pan, but if it had been necessary, the 4 bolts holes could have been milled into short slots. The circular ring fits inside the ABS riser, lining everything up nicely.
The top plate mounted to the projector. Again, 1/4" plex with additional strips around the outside edges to add visual thickness.
My complements to MonkeyMan for his initial mount design. It's very straight forward, works great and could be easily dressed to fit in with the design of my theater.
Now I have to make a themed shell to enclose the projector...
