When working in the workshop, I have a tendency to scribble notes on whatever item happens to be close at hand. This includes doodling sketches on the top of my workbench, or writing a hardware store shopping list on the back of discarded packaging materials that I dig out of the bin. A more permanent solution was definitely in order. So I came up with this simple scratch pad that uses a readily available roll of adding machine tape.
Basic construction. Using plywood, a few dowels, and a couple of strips of Masonite, the scratch pad is easy to put together in no time. The sides are joined by a pair of dowels and a plywood base that acts as a writing surface. Before shaping the sides, I used a straight bit in the router table to create the slots for a dowel that holds the roll of adding machine tape.
The two Masonite tape holders have a shallow trench on the underside that allows the tape to slide underneath. They also get glued in position.
