Historically- I've used Duralac (insulating jointing compound) to good effect. Sets hard (ish) and looks pretty in its yellow garb.
Good on spinnie things i.e.- join S/S hubs to ali fan hubs.
I shall expect even LESS noise from you as you glide effortlessly (nay imperiously) by.
Soon John, you will need an artificial noise generator to warn of your looming proximity.
Perhaps Jane could help here?
