I'm sure someone out there can help me out on this one. I need a 28ft. curved 4x6 timber for a curved deck. Curve is gradual - 30 inches on the 28ft. chord. My plan is to resaw a 4x6 into 1 inch pieces and glue it up in place. Should I plane the pieces before gluing them? What type of glue should I use and where do I get it? Thanks.
