I took a crack at cleaning up and shrinking this sketch and got it 
down to a 58k gif.  I will be happy to email this file to anyone who

And Chris, If you would like some drafting help making a more formal 
drawing of this device, I can volunteer a bit of time.  But we should 
do this off list, too, since it may take a bit of help from you, 
before I get everything the way you want it.
