Infocus 4805 Projector Mount from the lamp compartment side
There is a piece of plywood that is directly attached to the projector. I had some trouble finding the right size screw that fits in the projector mount screwholes. I ended up with size 7 screws (according to one measuring scheme.. 4mm if you use an alternate measuring scheme). Figuring out where the screws are at and transferring that location to the board (I used 1/2 inch plywood, because I had it handy) is a bit tricky. I took a sheet of notebook paper, marked the edges, and then poked holes where the screwholes were on the projector. I was then able to sit the piece of paper on the piece of plywood and transfer the location. Then, I drilled larger holes that the downward facing bolts would pass through.
