First we used a router compass to cut a perfect radius for the form pieces.
After the form was built we laminated a sandwich of veneer, bending ply, veneer, bending ply, and veneer in the vacuum bag outside the form.
We use the form itself and a pattern bit in the router to trim and square up the panel.
Also the ends.
Now we have a stable, square core.
Next we glue and clamp on 1/8
After the edging is on we flush it and put the face veneers on running perpendicular to the ones on the core, and put them in the vacuum bag and over the form again.
Here is the panel attached to the cabinet to create the island.
