I recently had the thought that since I'm building a woodie, that I'd like to build my own fenders as well. Using the same technique that you'd use building a cedar-strip kayak or canoe, you could use wood bending to shape a fender, and then fiberglass the end result. Since I'm having the templates for the side of my tear cut from a CNC machine, I was thinking of having him also cut templates for the fender as well. Then, it's steaming the wood, bending onto the mold, dry, and then move onto the next strip. Once all the strips are dry and conform to the new shape, fiberglass on the inside and outside with Epoxy, and voila! Of course this is much easier in my head. Just thought I'd throw it out there for discussion.
Mike.
