The gluing was done using clamps to hold the boards down tight on the outside edges while a batten is under the actual joining edges. Removal of the batten supplies the clamping pressure. You need to have something under the edges to avoid gluing the wood to the work board. I used wide masking tape.
Now I have to make some concave surfaced work boards to provide the caul pressure for clamping curved braces and give the back some shape. I'm also tossing ideas around for the belly rosette....I want it simple, but strong, too.
