Our “theater room” is 22’ long and 10’6 wide. Due to the layout, we needed to project across the 10’6, which made getting a large projection over so few feet limited to only a few “short throw” projectors.

When I checked prices on the mounts, I was appalled at the prices. It was an “I’ll just do that myself” moment. So here we have a painted wooden wall plate, connected to a white jointed swivel (that can be moved up/down, side to side, and tilt to level and adjust the projection to the white portion of the screen) connected to a wooden projector mount that is held off the projector with spacers made by cutting plastic tubing exactly to length for each position (the top of the projector is not flat and the mounting screw holes are not in a square or rectangle.

Screens are pretty reasonable, but since this is a dedicated room I had no interest in either portable or hiding screens. The look we wanted was custom built-in. Another “I’ll just do that myself” moment.

The screen is a bright white rubberized canvas stretched tightly over a 3/8” plywood frame, then the blackout mask trim (made of 1/4” luan and painted with satin black enamel) was added to the edges. Next, maple 1×4 with ogee edge was picture framed around that, then finally maple 3 1/8” crown was added to the top (with returns, of course) to serve as a crown pediment.

Final viewing distance from eyeballs to screen is about 9 feet. At that closeness, you will see a lot more head turning during action sequences, but no injuries yet. And everything is larger than life, which usually is (but not always) a good thing.

It was fun and the first of three that we have done, but I was (and always will be) the guinea pig for anything new.

Very nice build, I bet you’ll be enjoying a lot of popcorn and raisinets in this room!

Nice build, David. I perused your website and you’re a busy man with a lot of impressive projects under his belt. I can’t wait to see more of them.

Nselimis,

Sure. I will try to take a pic tonight for you. All projectors are a bit different, so the board that mounts to the projector with spacers is an exercise in three dimensional layout (although straightforward).

First determine mount hole location layout, then drill those holes in the wood. Then, with the board held / aligned over the projector (I propped mine with books) measure the distance from the hole to the board at each of the hole location for spacer thickness needed for that location. Next add the board thickness and threaded depth to these measurements to determine bolt length. Finally, cut each of the spacers from tubing and begin assembly.

Sorry about the wait on the extra pictures. I took them last night but didn’t get a chance to post. Hope these help. DG
