that last part about filling with epoxy, please look at a previous picture/diagram i posted on 1-23-03. does either of the two "plates" shown there mimic the plywood part of your reinforcement?
i can imagine that there might be a lot of epoxy to fill the cavity.
how did you keep it from running out the ends?

i guess i am just really paranoid over this reinforcement issue, probably brought on by the report of having track pull out coupled with the manual's discussion about the hull/deck joint and voids therein.
but thanks anyway.
