Looking for a big flywheel

[TechAUmNu]

I was originally looking at old car wheels, but then realized that most car wheels rarely go above 1000RPM in normal operation so running them at 6000 or so might end badly!

The engine flywheels are great, especially the RX8 as it can rev to over 10000rpm so I know the flywheel should be good for the speed I need to run it at. Plus it will be nicely balanced and has some big bolt holes for making it heavier.

I've found many a flywheel at local scrapheaps, might be a good place to look.
