For what it is worth, I have one of the newer VM120 chucks and it does have a locking set screw on the insert. I bought a spanner wrench with a pin to engage the insert. I have actually used that wrench and an "enforcer" pipe for additional leverage. I put the key in the chuck for the other handle. I did all of this on the spindle, but not tightened on the spindle. By screwing the chuck partially on the spindle, it acts like a third hand.
