The shaft is M3 threaded ... so you ream the rotor shaft hole to just UNDER a M3 thread tap size ... you then use the thread tap to cut the M3 thread into the rotor hub. I put 3 good fit washers on shaft as spacers before screwing the rotor on. This prevents the hub from grounding on the shroud mount area and motor screws.
The direction of rotation tightens the rotor onto the shaft so i don't even need a locking nut or anything else.
It was purely by accident I found this worked !!
But please use a tapered reamer ... do not drill out the rotor hub. Because of the taper - I reamed from BOTH sides so that thread tap wasn't going to split the hub.
easy peasy ...
