The only way I can think of doing it is to get a bit of 15mm and have my part sit in it.
Then when the vice clamps down, the slight bend in the aluminum locks that part in place. I am talking a tiny tolerance that will not bend enough to cause problems, but enough to grip onto the part.

I'd model it up but my laptop has crapped out on me. Thanks, Windows.


Also, looking to add a solenoid valve to the machine to turn the air on and off.
Fed up with having to reach in and turn it on and off. That and I run the machine and leave it for a bit. If it errors our or finishes the op before Ig et back, would rather it switch off the air.
12v is what the X6-2200L uses on control board right?
