Any number of possibilities. I wouldn't have thought it to be home made but it may have been knocking around someone's shed for years getting stuff leant against it etc and it may have copped enough little 'incidents' to put it slightly out of true or knocked the balance weight off it etc. it could have been anything though using my ipad I cannot quite make out of the rear uni or the uni boss may have let go?

I've seen some (mildly!) twisted driveshafts but never like that!
