I haven`t tried it, so this is pure speculation offered in the
spirit of a collective brainstorming.
Somehow I feel it ought to be possible to
1. inflate tractor tube
2. introduce polyurethane foam
3. tumble and turn the tube to get foam to adhere to all surfaces of
inside of tube
4. leave to cure, and perhaps form hollow toroid
5. sacrifice tube to toroid by performing caesarean section
6. worship toroid, and apply finish.
Cheers, Finn Hammer

Hello all,
Lets use the List group consensus to brain storm a way to make an economical
large toroid within reasonable effort that is strong, light, and smooth
enough to do the Saint Vitas Dance.
My limited experience proves that attaching a smaller diameter, say 4" minor
of dyer duct by 18 or 19" (scale as needed) added surprising plane rigidity
to the 8" x 32"+ business end toroid with dual pizza pans center. This
clearly reinforces the top hat which is still reasonably horizontal with no
visible plane distortions.
Ok, so we are down to the filling the ridges, and dent deterrent.
Bondo.
I grew up in Illinois, and became proficient in rust repair. It is very
formable and reducible in early set stages. Hey, there have to be more
solutions out there in today's high tech, divisive chemistry and epoxies.
I have to believe that there is spray on, reasonably low resistance coatings
at our voltage outputs.
Ideas folks?
