Axles and arbors for Used CD s

Standard parts to allow old cd to be use as toys or in conveyor lines.
  [vote for,

While never designed to be wheels, Three or four cd bolted together would make a useful and all but free tire/wheel for a toy wagon or other toy.

20 cds on axle would make a cheap conveyor line roll.

A business providing a schedule of twenty or thirty standardized axles, hubs, bearings, pillow blocks, brakes for use with "CD" tires would be natural.

Particularly in an old factory with outmoded lathes and mills. Steel, aluminum, and plastic versions should cover the waterfront fairly well. Worldwide online and catalog sales out of the same factory. Might bring some small town back to life.

       Nice idea.   

       Not sure it is going to bring small towns back to life, but nice idea.

       Might be a small town in China, but...

       An impromptu practical experiment shows that it is perfectly possible to fit a CD onto the arbour of a small angle grinder, and spin it up to 10000 rpm.   

       However, its properties as a cutting tool are best characterised as "non-optimal", catastrophic brittle fracture being the predominant failure mode.

       I've seen a wall-sized fish mural made entirely of CDs. I envision a town with CD float competitions and parades, where a king and queen of second-hand CDs in flown in from the 80s every year.

       "Axles & Arbors" - sounds like a tabletop roleplaying game.   

       " Eighteen - my plus-four heavy metal double album does (sound of CD collection hitting the table) ...twelve damage to the eponymous pop artist single ! "

       You can also use the little circles in the cassettes from tape recorders. But what will you do with disk on keys?
