My plan is to prime the entire hull with epoxy for a good bind before the application of fiberglass/polyester skin. I want to introduce this idea to the poor fishermen in the Philippines for economic reason. Polyester does not bond very well to epoxy. Most authorities advise not to use this method. The "old" system was to use thin polyester resin to impregnate the wood. Then use polyester resin to "glue" it together. Many boats were built this way in the early days of "fiberglass" construction. I think I'd question your idea. Why not just use waterproof plywood to build boats? It has been done successfully for years now and I would guess that the Filipinos are well aware of how to build boats. Cheers, Bruce (bruceinbangkokatgmaildotcom) They are still using the old practice of cutting trees to make a dug out canoe for the bottom hull with extented sides made of plywood. The dug out canoes are being sold to the local fishermen by those illegal tree cutters. I like to introduce the stick and glue to eliminate the dug out canoe which will be cheaper for them and will save the trees. This is the native Banca using outriggers on both sides. http://www.pixelmap.ca/canoesailing/- Hide quoted text - - Show quoted text - for their own good.......right. |
