please help me solve this as i really cant afford buying one of these expensive mounts. thanks
No big deal- do a 2-plate design.
Just buy the appropriate fasteners for each of the two different holes. They are most likely metric, though they could be english units. Measure the approximate diameters with a ruler, then buy several sizes around this approximate measure- return what you don't use or store them for another project.
Clamp a plate similar to the commercial mount against the projector (without all the extra slots- only the holes you need) with the screws/bolts you buy, then arrange a 4 hole bolt pattern for 4 fasteners to connect to an upper plate, which mounts a flange and pipe.
You could use MDF, plywood, or plexiglas, all covered in this thread.
The benefit of plexiglas is looks, easy to cut and snap by hand without special woodcutting or metal working tools, and easy to transfer the hole pattern from the projector to the plexiglas- just lay the plexi on the projector and mark the holes you see through the plexi.
With MDF or plywood, you could countersink or counterbore the holes for the bolts connecting the upper and lower plates together, allowing clearance for the bolt heads if this is an issue, to keep the plate flush against the projector.
