The next step is to size the top and bottom in preparation for cutting the grooves and rebates in their edges. Paul uses a cutting gauge to minimise damaging the edge when using the plough plane. The rim is planed before the sides and ends are grooved to receive the lid. Then the optional housings for the divider can be cut and the sides can be rounded. The final step before gluing up is to cut the pins flush with the main body of the box.
