ER collet won't let go of stock...

Hey, Apprentice, there is one other thing that is hard to find out about until you run afoul of, but is vital in using an ER collet. Never, ever, put an over-sized piece into the chuck. Even .001 oversize will cause several problems that you will have to experience to believe! The worst is that the collet can 'weld' to the work if it is really soft like cast aluminum or soft brass. You can spend hours separating them!

How would you mount the LMS chuck? I am not familiar with your lathe. Do you need a backing plate too with that chuck?

Well, I may have to do some checking incase I am over-simplifying things. I was under the impression it just mounts using three M6 bolts to the spindle. No backing plates needed.
