Another mounting question, if you can bear it.

After removing the big flourescent fixtures, leaving behind a big, ragged and crumbling hole in the plaster they were concealing (I am trying to not even think about the fun I will have patching that without bringing another 10 square feet of plaster down in the process. *groan*), I was finally able to get a solid idea of what and where the joists were.

(Yes, I know how to correctly spell "lath". I have visions of home theaterness dancing in my head, give me a break. ;-)

They are big suckers, 10" x 2.5", on 16" centers. So far so good, no support problems there!

The trouble is that they don't really line up in any symmetrical way with the room.

The dotted line is the room center.

What do you guys think is the best way to go? I had planned to mount the unistrut parallel to the joists for maximum support, but it looks like that is going to leave me with a weird off-center arrangement relative to the lower channels.

One way of solving this problem is to cut a peice of three quarter inch plywood large enough to span the two joists, then using number twelve screws or through bolts attach the rails to the plywood. That would distribute the weight evenly along the joists and give you something to screw or nail a trim peice to that will hide the ugly stuf.

You could put 2 pieces of unistrut perpendicular to the joist and then attach your other 2 pieces of unistrut to these. This would also give you a means of adjusting the projector left to right by sliding along the unistrut.
