Any time you're creating a project that has shelves—whether you're building something new or you're revamping an existing piece of furniture—making the shelves adjustable adds a lot of versatility. The challenge is drilling holes for the pins that hold those shelves. The holes have to be accurate, consistent, straight and evenly spaced to end up with shelves that sit flat and won't wobble. Here's a way to drill those holes with an easy-to-use jig. Visit link in the Extras tab for more information on the jig used.
