Re: [TCML] DIY dent-proof Toroids

I'm sure it has been mentioned before, but why not use a vehicle inner tube as a mould. The only disadvantage that I can see is after you have cut off the tube, you would need to glue in a centre disc which wouldn't be as strong as in Phil's design
In the UK, the cheapest source of aerosol expanding foam that I have found is Toolstation

>Perhaps "spin-balancing" while it cured would solve some of the distribution problem, especially if done in several steps, building towards the inside to allow proper out-gassing. When in a confined space with some air, the out-gassed fumes from "Great-Stuff" foam are nicely explosive!
