Thanks for the help. I went ahead and made make-shift free standing shelf that has four blocks of wood underneath. I will start with the highest, which is 62 inches and then take the blocks out until the projector hits without any problems... after that I will actually build the shelf.
With just a fan in the way, is there any reason for me NOT to mount the shelf in the middle of the screen? I know the espon has great lens shift, but they work against each other H and V... I figure the closer to the center of the screen I get, the more Vertical shift I can use instead of horizontal.
It makes sense in my head, but I don't know.
