I'm considering trying to make some more portable hoops. I want the bits to easily come apart and go back together, but I also need the hoops not to fly apart when I'm spinning...

I found a site with a method that looked interesting here:

And searched out a few places that will sell the part in the UK.

www.east-coast-leisure.co.uk/mod....asp
(Thought I'd share the links as it took me hours to find them!)

Anyone else tried anything like this? Or using a different method to make collapsible hoops?
