Edge Gluing Carvel Planked Hull8/21
I've been reading up for this application and sounds like Resorcinol would be superior than epoxy for this application. Do you carry both the "summer" and "winter" types? Because I'll be doing seams after planking I'll need a light filler with no clamping pressure.
I've heard concerns raised by traditional boat builders that finishing off the hull with epoxy, after edge-gluing, then two-part varnish will not hold up due to boat twisting, etc. Do you have any experience in this area?
Is Resorcinol more able to withstand this "flex" than epoxy-based adhesives?
Or should I just edge-glue then use traditional varnish?
PS - Planking is all new (but seasoned) philliphine mahogany
Both carvel and lapstrake hulls are not glued at all but chalked (they are glued and screwed to the frames but the seams between the planks are always chalked). A carvel or lapstrake hull does "work" (flex) in a seaway.
Strip-built hulls are edge-glued and cold-molded hulls are cross laminated. What kind of a boat are you building?
Canoes, and kayaks are often made from thin strips, edge-glued and sheathed in glass and epoxy (inside and out). A transparent "bright" finish is an option.
Traditional wood planked (carvel) hulls are chalked and painted with marine coatings. Varnish is not recommended below the water line.
And...Philippine Mahogany is not generally recommended for planking since the wood absorbs water. You might therefore want to consider a penetrating epoxy sealer prior to any chalking or paint.
Be very careful. Jim Baldwin is right on. The planks are not edge glued at all. Even the most modern runabouts are not edge glued when solid planked. Typically the caulking would be flexible and never rigid. Sika flex or 5200 is even difficult to repair ten years later when the occasional repair is necessary.
U can edge glue and dowei carvel.. it is done with vessels that r going tone out of water for extended periods..
