[Rhodes22-list] Re design of Rhodes Interior and elimination of compression post.

Mon Apr 13 12:39:57 EDT 2009

Hank,
A good reminder about deck strength.  I imagine that if the chainplate were connected into the ends of the beam replacing the compression post it would be the most sturdy.  I wonder if a wire connected between the beam ends woukd remind it to not unbend.
