Ceiling Mounting to be able to change projector distance

[wbond]

Thought i would post what i did to mount my projector. I have the Optoma GT1080 which is a 16:9 native. I knew the kids would like watching movies in the summer so I wanted to be able to see them in 16:9, but still be able to use the sim at 4:3. The image width changes based on resolution size and i wanted to keep the full width for both. To do that, the projector needs to be able to move back and forth from the screen. Originally i tried to slide it along an emt, but the projector in the mount doesn't sit square, it hangs off to one side. So that didn't work. Instead i built a two track system out of angle iron that is square to the screen which allowed me to move the projector. The projector mount itself is attached to two pieces of angle iron that sits on top of the track. All you do is lift two bolts and then you can slide the projector to any distance you want.

This also allows you to dial in image size easier. It may take a little more work, but I think it really helps in the end.

There was an aftermarket type plate that allowed sliding for and aft for this purpose. Not sure who provided it though, but some people did get it and posted pictures of it.

Bumping this - I’m thinking about doing something similar to allow the projector accommodate different use cases at 4:3 and 16:9, I will need to be able to slide the projector back and forward about 1metre. Is there any solution available on the market, or is this going to be a DIY job? Cheers
