I got a set of prints from the Adirondack museum, it had a set of offsets to loft in to the ribs. I stapled the skin on to the frame which end up covered so as not to be seen. The ribs are glued and screwed to the bottom board, I screwed and glued the top inside gunwales to the ribs. the rest rest of the stingers I glued and carpet stapled them on the ribs. The electric carpet stapler staples are 3/4" long and have held in place very well. The ribs are 1/2 ply wood the bottom board is 3/4" pine 14' 2" long. I scrounged most of the material from industrial areas around me, There is a lot of wast in piles behind buildings that no one wants. I panted the frame before I covered it with epoxy paint. The oars are saw'n and shaped, with the blades being fiber glassed. The oar then gets 6 coats of spar varnish.
