Clamp the wood pieces to a flat surface. A piece of paper from the newspaper or the phone book keeps the glue from sticking to the flat surface. I placed the flat piece of steel under one of the pieces of wood before clamping to lift it so there would be a raised edge at the joint that I could use to align the piece of steel when fastening it to the wood. The edge of the steel will need to bisect exactly the angle formed by the two pieces of wood. The glue line is on the line that bisects the angle. While the glue is not yet hardened scrape away the excess glue with a chisel so the raised edge is clean and sharp.
