Once your six pieces of timber are cut you can join them together. Placing one piece of timber on the workbench, apply a bead of wood glue to the end of another piece. Place this piece next to the first piece and clamp them together, making sure the angles are flush. Nail the timber in place. For each side, pin the top and bottom at opposing angles to help ensure a better join. Nail the centre to finish. Repeat this to join all six pieces of timber, making sure all edges are flush.
