A plug for laying up the fiberglass seat was made using several layers of 3″ insulating foam. This foam is very easy to work using tools as rasps, hand saws and coarse sandpaper.
Most of the techniques for making the seat, came from this video by Herm Narciso of Dime City Cycles.
After the basic seat was fabricated, I decided to make a stop attached to the front of the seat. The photos show how this was made from foam and layered with fiberglass.
