Gluing plywood to hull

Hi Mike,
1/64 birch plywood is thin and bends easily. Align the grain fore and aft to make it easier. Make cardboard patterns and cut the plywood out with sharp scissors. The two holes are for monitoring the glue amount under the wood. Roughen the hull under the wood with course sandpaper, sqeegie slow epoxy onto the hull and back of wood, slip the wood into the hull keeping the top pulled out. Pour epoxy (20ml?) between wood and hull. Test fit the top into hull, pulling it out to add glue until glue is up to the holes. Clothspin the top into place and as the glue settles in, top it up through the holes to keep it full. You are done watching it when the glue can't be worked anymore ( hour). Let it set overnight and do the other side the next day. You can now add gussets to brace the keel box as you like. The plywood bends flat like a soup can, the hull is round, but also curves in to the bow and stern, causing a void under the wood to fill up. There will be no hull flexing when sailing, but it does add some weight. I prefer the weight to seeing something separating from the hull later.
