I made a chipboard template that use to trace a "topographic map" onto the solid spruce top wood. Each concentric line represents about 5/100" in height difference.
I have a router mounted on a large piece of plywood that rests on form holding the top or back plate. I can set the depth of the router and cut up to each line I have drawn.
The lowest area is cut first. I then raise the router and cut the next ring for 11 different levels.
After all the rings have been cut, it looks like this.
Then I use thumb plane to carve the top plate and blend together the different levels. Then lots of scraping and sanding to get it to the final outside shape.
