Here is the final "Block" that will be the basis of the case. I cut the Alder down into lengths of around 8.5", planed the mating faces of each of the four pieces, then glued and clamped them together. After they dried, I trimmed each end using a table saw and planed the top and bottom. Finished with hand sanding from 80 grit, 120 grit, 320 grit and 400 grit paper. At this point it is a solid block. I will use a combination of a router table and drill press to hog out the inside to create the final shell shape.
