The problem with scrap wood is that it never seems to go away. No matter how small I seem to save it. Especially short pieces of 3/4"thick wood. Whenever I'm experimenting with router bits I always head to the scrap pile and do my first cuts on the scrap. But then since I can rip that piece of wood down the middle or use the other edge I save it again. If its a piece of good hardwood I may run it through the planner and use it for small drawer bottoms or puzzles or who knows what. When I can't use it anymore I'll burn it in the fireplace only to realize in a few days that I really did need it.
