Platform revisited

I was motivated to work on my custom railway platform after having seen some of the displays at the train show. One of the exhibitors had used a small miter box to cut multiple strips of balsa wood to equal lengths, I decided to try it with plastic. I always thought my platforms were a little plain looking and needed some additional architectural detail. So I decided to add ribs to the sides of the platforms. However, I was not keen on cutting strips of plastic. I couldn't imagine myself measuring and cutting 1020 ribs. However, the miter box was a real time saver. I secured a metal barrier on one edge of the miter box so I could press the strip of plastic against it to ensure each cut would create the same length without having to measure each time. You can see how I set it up in the photograph. Originally I used a saw to cut the plastic. This created a ragged edge, which I had to sand down. I found using an Exacto knife created a very clean edge. However, the slots on the miter box was a little too wide so I used two pieces of cardboard to keep the blade firmly in place and at right angles. It worked like a charm. I simply pressed down to score the plastic strip and then simply snapped the rib off. I figure can finish one platform per night. Hopefully I'll be done by the week-end.
