The side project is the downfall to almost any project that the DIY's take on. You all know what I am talking about. The side project is the idea that comes up when you are working on something else. It is usually an attempt at a solution to a smaller problem that pops up. A great example of this is the piston pin press that I just built. I needed to removed piston from my connecting rods but wanted to do it myself. I had a bottle jack lying around and gave it a shot. It was a great success. See the posting of it with the video.
