Balsa fish update.

This project is going along as planned.  My goal is to simplify the building process.  I'm happy with the weight and strength of the board.  I also did some research about balsa.  It's a very common plant and a viable renewable resource.

I used 5" wide shrink wrap to install the first rail strip.

It helps to spray the rail strip with some window cleaner that contains ammonia.  That makes the balsa bend a little.
