I just put the 9000 on order i look forward to useing it . Be awhile before i can use it im laid up for a few weeks from eye surgery, but it will be put into action as soon as it gets here . We been useing a rbg 3410 and it is a little hard to get the correct angle ,i hope the 9000 does a better job at maintaining the correct angle. I would just like you to know without this forum we wouldnt have thought about your product most of the supply catolog dont carry your grinder . We have your balancer and love it.
