Which workstand?

Yeah, that wasn't very well descibed - i was under the impression that the pcs-9's clamp could be auto adjusted. Whereby you adjust the tightness for a particualr diameter tubing, lock the clamp in place, and then it can be automatically adjusted to that tightness every time - so there's no risk of overtightening and damaging your tubing - if you don't have a clue what i'm talking about, it's probably a feature of the pcs10, and i'm just getting confused.

the clamp on the pcs9 is simply a screw in thing so you tighten it as much as needed every time, no risk for over tightening
