Small caveat about installing a (rigid) plywood bulkhead inside a glass boat: because the hull (and deck) flex under load -- even at the bulkhead locations -- most mfrs use a bulkhead material which can stretch or compress. Mine have bluefoam bulkheads. Strong enough for my uses, but unfortunately not strong enough for a pump installation. This reduces the chance that the seal around the bulkhead (to the inner hull/deck surfaces) will fail when the hull "breathes." Mind you, I am offering the following in complete ignorance, having never tried what you are up to, but: you may need to surround the plywood with a 2-inch by 2-inch "collar" of minicell or somesuch to provide the flex needed. Being that dimension, the minicell should be able to withstand the lateral forces your pump arrangement will generate when you activate it. I bet Matt Broze knows what is best to do here. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced outside PaddleWise without author's permission Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************Received on Tue Jan 18 2000 - 18:22:57 PST
