Step 6: The Neck Support
Take the 46 inch piece of 2x2, and mark accordingly where you need the neck supporters to be. This depends on how many guitars you have, and how much spacing you want in between them. It took my father and me forever to do this. Sorry for the inconvenience. When you are done, screw the 2x2 into the two standing 2x3s. Make sure the dowell pieces face outward.
