> Should have added the following description to the radial plate link

The currently available radial plates are mechanically flawed.  Now, if 
someone designed a radial plate that allows use of  2-hole lugs, perhaps 
that too would meet today's lax novelty test.  The plate could support use 
of either single, or 2-hole lugs like these:

The 2-hole lugs: (1) effectively double lug to plate conductivity; and (2) 
prevent the lug from spinning and loosening on its mounting bolt when 
accidental lateral pressure is applied.  There, that's enough to start the 
first claim.   Any takers :-)
