I'm constructing a neck out of a large maple/walnut/maple laminate. So, rather than doing a scarf joint, I simply bandsawed the profile. Using a belt sander with the angle properly set I was able to clean up the bottom of the neck to a perfect 3/4" starting point. The headstock, on the other hand, confounds me slightly. Because of its width and shorter length it's just not practical to try to use the belt sander to get it to a consistent depth. I've hand sanded it, attached the wings for sufficient width, and hit it on the belt sander to get the wings to the right approximate depth.
But in order to accurately plane both the front and back to a consistent depth, what is the best method? Using a hand plane? I thought of trying a router with a pattern bit, but it would take quite a jig to get that set up properly, and I don't think the router I'm using has sufficient plunge to make it half way across the face of the headstock regardless. What do you guys use in this situation?
