as for rpm. if you have the latest model, should be 6k. old one was 3500. i wonder if they just used the wrong motor. you could try to look for the label on the motor, but its tucked inside the head so might not be able to see it without removing it. |
Yes, it is spindle runout - I'm measuring the runout both on the inside taper (angled the dial indicator up a little to get it in there) of the spindle and the outside (the collet is not attached) - the two measurements are the same (IIRC), and they're not good.
Based on your wrong motor comment - I removed the wire egress plate on the head to take a look at the motor - sure enough, I can see enough of the the motor label to read "3500r/min". Blarg

. My NM-135 is supposed to be Rev2.1.
