After bending the two sides I bend the cutaway portion by hand using a hot pipe and water. All the pieces are in the form ready to glue together.

The linings are glued in around the top and back to provide more gluing area. I use clothespins as clamps while the glue dries.

I start with a slab of sitka spruce and cut it into thin pieces, then shape the pieces to make the bracing wood for the top. These will be glued to the underside of the top to reinforce it.

All of the internal bracing has been glued in and the top has been glued to the rim. Now the back can be glued on to complete the box.
