There are also dynamically balancing hub designs that look simple to implement:

but like everything in life, there are multiple ways of doing things.
you are showing a surface grinding wheel, not a bench grinding wheel.
it's different, but the dimpling is still something supported by many old timers.

True, I have seen hubs that use liquid in them to do the same.
I might try one of those.
