I hope the cone spinner assembly has been machined to center on the shaft without the need of the blades.

What to I mean???

If one removes all the blades and assembles all the aluminum parts onto the adapter, they all align on center except the cone. It has no aluminum support/lockin/alignment . It relies on the plastic blades to "center" itself and to stay centered at the high rpm range.

The cone extends out and is one of the more important components of balance and wobble.

I have a retro fix for mine. I'll post it once it's done. Would work for many fan systems as well.
