I normally do not work with plywood, but sometimes you acquire some, and just do not want to let it go to waste. Instead of making a box or a shelf, or a table top out it, I decided to make something I had a need for. In this case it was an organized way to store my set of drills that would get them off of my table top, while keeping them readily accessible while I am working.
Sometimes after you create one project you find yourself finding a need to build a similar project for yourself, and you feel it's not right to take ownership of an item that you were purposefully building for someone else. *laughter* So I decided that I should just make another one instead.
