Not to long ago I glued up a wenge/purpleheart/maple/mahogany/maple/purpleheart/wenge neck blank. Just a few days ago I noticed that it has a slight curve it it. The blank is about 52" long. With a straightedge touching both ends, the gap at the center is about 2-3 millimeters. I figured I would be able to correct it by routing down the center following the curve (the center piece of mahogany is 1/4 " thick, so I would use that as a guide), and then forcing the truss rod into place. The more I thought about it, the more I figured that it was a really bad idea. Any suggestions on how to correct this?
