There are a lot of different ways to make a door harp. I kept mine simple, using only three strings. Making the box was easy. What gave me the most trouble was figuring out a way to attach the strings. I looked at a number of methods that guitars and other stringed instruments use and then browsed around the music store to see what I could come up with. Aside from being expensive, most people dont want to hunt down specialty parts for a weekend woodworking project. So I came up with a method or tightening and tuning the strings using a nut and a bolt.
