So your thinking that the centrifugal forces are what sheared the rivets? It's pretty crazy how high the forces spikes could be from an unblanced fan. I've not see one yet that was just built and installed w/out being balanced and lived for any period of time. That kind of stuff fails spectacularly, once it starts to go you couldn't stop it fast enough to stop it from exploding.
Can't argue one way or the other. All I know is that it came apart completely, and I wouldn't trust another constructed that way to last any longer.
As far as cnc'ing one, sure that can be arranged. Are we talking from billet or a casting or..? Material?
Would a cast object be able to hold together? I was thinking that with a CNC, a machined billet one-off would be the easiest route.
