I am new at posting pictures on Picasa.  I posted these, but I reduced =
their size first...Maybe I should not have made them so small.   visit =
http://picasaweb.google.com/tchannel33 If they are too small, don't =
hesitate to email me and I will send you better ones.  I also have more =
pictures, with greater details.

The posting just show the idea.
I first made the Normal pendulum straight, not like a "C", and made the =
inverted Pend. Like a "C".  This made it Left side heavy, it worked but =
this C+C worked better.
Chris pointed out I could have made both of them straight, and in the =
long run I should have. I have a design for a straignt approach to both =
pendulums............. But this worked.
You can't see in the picture, but the hinges are two pieces of .018" =
brass music wire.
That's two pieces on each of the 4 hinges=3D 8 total wires.  1/4" =
exposed wire, 2" behind the plates. 1" top 1" bottom.

Plexiglas to cover the front.
If you have questions or want some good pictures, just ask.
