Anyone have any resources to point me too on this one?
I have a spinner with a kevlar backplate that at about 1600 RPM really starts to wobble. I've just added (bonded) a high grade aluminum doubler to the backplate to eliminate a good bunch of flex... Now to fix the real issue, the dern thing needs to be balanced!
I'm pretty handy, is there a balancing tool I can easily fabricate? I've thought about a level and a plumb-bob type system, but worry about its accuracy.
Any ideas would be VERY welcome!

I hope that this suggestion from an inarticulate clodhopper will not put you further behind, but here goes.
I remember that eons ago, some builders were making their spinners from a disc of aluminum on a lathe. They were spun using a tool that had a roller on it. Oriental woks are made from steel this same way and sometime in primitive settings.
I have a half formed idea that also uses a lathe or wheel balancer. It could be that the spinner and back plate are off a little. I wish that I could be more help Good luck.

I made on a lathe an aluminium prop flange, 2 ball bearing in it, then i mount in a vise and I balance statically the plate first with some epoxy plaster, then I mount on the spinner and I put inside some other plaster using my fingers trought the prop holes
