Oh man and I am relieved!! I was really getting worried about the decision to get this projector since a lot of the ideas involved ripping down the shelf. Basically I took GarenT's idea (thank you) of a 2x4 as the top mounting plate for the projector mount. And then I made two side supports, to make it into a stand. Then I cut it all to fit and screwed it in place, it's not going anywhere now. I can't believe I didn't think of this and wish I didn't drill holes into my shelf bottom!!
I also had to rebuild the shelf projection for the anamorphic lens, but I got it all figured out.
Here's the fluted air vents per Big's design. I installed the mount and the 2x4 so that the rear air vents on both sides lined up perfectly with these air vents.
Anyway, all that steel I posted a pic of earlier...$200!
All I used to make this was 1 2x4 and 1 can of black spray paint. The screws I already had. Total cost... $3.00
I'm taking the metal back tomorrow. I'm really happy that I was able to do it, I wasn't happy at all with it mounted to the bottom like it was. So thank you all very much for the help!!! Now I'm gonna program my harmony rf receiver for the projector and get that all set, clean up and watch a movie
In the next few days I'll have to patch up those holes I made in the shelf bottom and repaint.
