plywood for a tiny boat in Sydney, Australia?
Nice to see a kindred spirit in the newsgroup.
Look for Herb McLoed's one sheet skiff, Gavin Atkin's Mouse, and Prizm by a guy in Finalnd, all one sheeters. Also look in www.ncf.ca/~ag384/Boats.htm for the small boats I've designed and built for myself. The plywood of choice if underlayment. It's nailed to floors to go under vinyl and other flooring, hence it's name. There are three kinds. Luan and meranti are essentially the same, some king of Asian cedar. The meranti I've seen has better surfaces and frwer voids than the lauan. They weigh about one pound per sq ft, the same as okume marine plywood. Virola, the other kind is from Brazil, weighs half as much as lauan and meranti, bends a lot easier, but resists water like tissue paper. I've build two boats out of it and have to keep sealing surface splits and gluing pieces of surface ply back on. All three are very cheap. Look along each edge and pick sheets with no gaps "voids" in the edge. If voids are unavoidable they can be filled by drilling holes and forcing in caulk or glue with a caulking gun. These boats last longer if stored inside, for example in a garage or carport. I use screw and glue construction with chine battens cut from cedar 2x4's and then cut in half to make 3/4"x3/4" battens. The glue is LePages' Bull Dog brand PL Premium polyurehtan construction adhesive in the caluking tube. Very cheap. The outside seams are rounded with a sander and sealed with a dab of polyester resin spread with a toothpick. The finish is semi-gloos latex acrylic house paint below the water and linseed oil everywhere else. The way to reinforce the thin plywood bottom is with a keal or skids on the outside and if nececessary bits of plywood glued to the bottom on the inside. I don't know why Google groups doen't have a spell checker... |

If you "pet" the panel all over with a flat hand, many times you can "hear" differences in density in this type of thin, usually pretty dry, plywood. Also look for a sticker on the sheets that say "TYPE III". It will at least be made with water resistant adhesive. If you are going to use other than marine, this stuff, in my opinion, and as available in my area, is much better than pine or fur for boats. I actually have a couple of sheets put away for a special project that came with a wild grain and was probably some other "filler" wood that was used in manufacture. Maybe an end sheet or something, but it is beautiful. I may make a small kayak or skiff out of it, the kayak would show off the grain better. |

Scroll down to the two articles on "Baby Canoe". I think there's enough detail for construction. It's more like building a bigger boat than any one sheeter I've seen so far. Also, it's a good idea to make a cardboard model or two before beginning to build a small boat full size. |
