Your thoughts would work with a lot of work. If you want to make a mold
start with an inner tube and use much less work. Inflate the tube to the
size you want and cast your plaster of Paris 1/2 way up the tube then spray
the surface with mold release or soap. Drill 4-6 guide post points with a
1/2" drill then cast the remaining top half. After it cools and dries remove
the tube ,coat it well with mold release,soap,or Pam (spray fry grease) and
cast your toroid. If you want to use fiber glass you only need 1/2 of a mold
as you make only half at a time and bond two half's together to form the
toroid. Then put a final coat of resin and graphite and plate a metal
coating or metal tape wrap it.
