Step 3: Neck Cutout
This next step includes routing, chiseling, and drilling. The first thing you need to do, is to take your guitar neck and trace it onto the top of the guitar. Now, you should take the router, set it to the right depth, and stay close to the line. Now you should clean up the corners with a sharp chisel, and if necessary chisel the space bigger. Now you should place the neck in the space and mark out where you want to drill the holes. You then should take the correct size drill bit and drill out the holes for the screws, but do not go too deep. The easiest way to install the neck is to soak the screws in soap, so they go in easier.
