Short answer,
Because a proper mold for a production TD would cost as much as $30,000. Fiberglass is a petroleum product that fluctuates with the world price of oil. I was roughly quoted $15 per square foot of 1/8 inch thick chopped glass blown into a mold. Add the surface area up and you get one expensive TD. The possible shapes and contours of fiberglass are nearly unlimited however the more complex the shape the more difficult it is to insulate.
There have been many attempts at FG TD's in the past. There are at least two other members of this board that are experimenting with it. One has posted pictures of a mold on this forum.
I think that once the grass roots community makes TD's popular enough for the mainstream fiberglass manufacturers to take notice one of them will mass produce a FG TD. It will be expensive and thus probably find limited acceptance.
There is a manufacturer on the net currently however I’m don’t think they have built many so far. Check out http://www.pull-toy.com/home.htm
