It won't be cheap to build your own.  Wonder how they put the divinycell together.  I was thinking Coosa or Space Age with the reinforcing strength of fiberglass built in.  Still 40% lighter than plywood and I know it is strong because my floor and hatches already have it as a core.   Thanks for the legwork and info.  Did you ever find the picture of them laying up a bracket?  I swear I saw one on their website somewhere.
