One problem with fiberglass shafts is that you really shouldnt make any cuts into them, only cut them lengthwise. If you are just running a wheel with bearings in the wheel and pillow blocks, sure. But if you want to cut a keyway into the fiberglass, you seriously weaken its strength. Fiberglass relies on the continuous glass fibers in it for its strength. If you cut the fibers, they lose their strength. If you can get a company to form the fiberglass into a keyed shaft, that would work very well. But... no cutting!
