Da' Beam
I studied this idea, even drew up some designs and discussed the concept with Roger for a wood core carbon/epoxy version, but came up with all sorts of nagging problems. Like how to attach it to the two half-bulkheads. By the time you figure all of that out you may not save any money ? The beam does work as designed. The guy that fabricated my replacement beam told me that if Jensen had "hot-dip galvanized" the beam in the first place it's likely that none of them would have failed.
