Balsa deck core

I presume you are saying that all my secondary bonds like bulkheads, liners, water and fuel tank supports are about to let go. Epoxy has it's place, ultrlight racing boats where the same strength can be had at much lower weight and as a glue resorcinol is a pain. I live e in what used to be the hub of boatbuilding in Canada and have seen many boats new and old repaired with the same material they were built in that is polyester none that I know of have yet disintegrated. John Hey, I've seen many boats built with polyester that had the tabbing pull free from plywood bulkheads. You can use polyester if you like, but given the amount of epoxy you're talking about for a 20' deck repair, the cost difference is trivial. And I think 2 x 12 oz biaxial would be ample for an inside skin, given typical spans you'd find on this size of boat and a core thickness of = 1/2". Evan Gatehouse |
