Or bottom. Whichever you prefer. It’s also of black walnut.
First I resaw 2 pieces 1/4″ thick, 4-1/4″ wide, and about 32″ long. I run them through the planer until they’re about 3/16″ thick. Then I joint the edges so that the seam is as perfect as possible, then glue them together.
After the glue has cured at least an hour, I plane both sides until they are flat and clean. Then I take material off until it’s just over 1/8″ thick. Then the outline is cut out.
Then the top is done, pretty much just like the back, except it’s made of western red cedar.
