I have posted photos of my homebrew tiltplate at:

I basically copied NN4ZZ.  He wasn't selling them at the time.
At this time, I'd recommend buying his plate.
The piano hinge concept didn't seem to make sense for a MonstIR.
If you come up with a design that works, please let us know about it.

I did build a light duty tilt plate using door hinges (piano style).
We used it on Field Day to put up a 204BA 4 element 20 meter beam.  It 
worked fine, but was a fair weather solution.  If there is sufficient
interest in the Field Day design, I'll try to put that up on the
web site.  A mechanical drawing of it is available.

I added a latch of my own design to the MonstIR tilt plate to keep the 
beam level when the wind blows.  I operate the latch from the
ground with a 20 ft pole.  Photos are up on my web site.
