Hunter 107A spin balancer

[Don]

Picked up a nice spin balancer a couple days ago ,had the 14,15,16 inch rim adapters with it,but the 16 inch was still not big enough to fit where the beauty ring fits.
It also had a 10 inch adapter,was just wondering if I could make an adapter where the hub cap fits and use this 10 inch adapter to mount the brain to and get good results ?
I could probably modify the 16 inch adapter to fit where the beauty ring is but the brain would still be at the hub cap position. Tks
