The drawing show as step # 2, a layer of tape and resin on the inside chine/bilge seam, that being the initial connection after the wire ties. How do other people start to glue them up? For their kayak kits, Pygmy Boats recommends you simply fill in the outside seam with thickened epoxy (use wood flour if you will finish it bright; wood flour or silica if you will paint it) to glue the panels together, then remove the wires before doing any taping. The epoxy glues the joint and serves as the base for the tape/cloth wrapped around the joint, reducing the probability of voids under the tape. After that, lay the cloth or tape on the outside and squeegee in the epoxy. Finally, fillet the inside joint with thickened epoxy before taping. The rounded fillet will give more strength than the sharp turn of tape/cloth. Would I then create a fillet with epoxy and filler? or is the tape and resin the source of the strength?. The epoxy in the joint provides strength to the joint itself, but the tape and epoxy distributes the loads around the joint, making it even stronger. The fillet on the inside also serves to distribute the loads. The drawings show two layers of tape and resin on the outside.... Designs vary widely, from taped joints only, to several layers of cloth over taped joints. Follow the plans initially, until/unless you find you need more strength somewhere (at the price of more weight). |
