wire wheel balancing

["CHARLES JOINER" <CJOINER@toltec.astate.edu>]

Local tire place says the outside hub surfaces are not always 
perpendicular with the splines  and cause the wheels to wobble on the 
spin balancer.  This makes true balancing difficult if not 
impossible because the balancer wants to compensate for the wobble.  
The only acceptable method I have found is to bubble balance.  This 
doesnt do as precise a job as I would like.  Any thoughts?
