After cutting out most of the pieces, the next step in the process is to fit them together. Much of the joinery in the trunk consists of panels and tenons inserted into grooves. Here you can see some of the progress I have made in dry fitting the pieces together.
The key to constructing the top is the curved ribs which define the shape. Each rib is mortised into the front and back rail, and the panels fit into grooves. Since there are so many pieces to the top, the trick is how to assemble them in the gluing process quickly enough so the glue doesn’t begin to dry out too soon.
