My next project is going to involve a couple of bent laminations, with quite a few layers (16). Each piece is going to be about 2.25″ wide, and 78″ long, and the will be bent into an approximately 5′ radius. I’m using padauk, and my plies will probably be about 1/8″, and I need a finished thickness of 2″.
After digging through all my old FW magazines, I see that polyurethane glue is recommended for bent laminations, so I picked some up. Now the articles also mentioned that you don’t need as much polyurethane as you do your standard yellow PVA. So, my question, do I glue both sides of each ply, or just one side?
