Here's what's happening on the top. I couldn't resist starting to carve out the back, staying well away from edge, as the linings aren't installed and the blocks aren't shaped yet to give me my inside outline. I've got the edge pretty well refined and almost ready to purfle (after a bunch more practice). I just got the stew-mac dremel routing base today. I ordered that imediatly after practicing cutting and picking out the channel by hand on maple and spruce. Talk about tedious... I've been looking at archings for awhile now trying to figure out what I was going to do, but until I started carving there were so many things I didn't even know to look for. Some basses I look at "bubble up" right from the edge of the fluting. Mine is a more gradual arch, trying to maintain a "cylinder" down the middle as opposed to a figure-8 shape. This is what my mentor does with his violin arching and I sure hope it works well for bass. I like the look better myself.
