I also recommend Rick. I have several of his pin chucks. I also have the expanding one from Arizona Silhouettes. Both work equally well IMHO, but Rick's are less $$ even at full price.
 
LMAO..:biggrin:

I just love how PSI's 'Patent Pending' design seems to work exactly like something I showed here for dismantling pens, some time ago....:rolleyes:
Sure, they use the method to turn closed ended and I made mine to remove mech's .....but the principle is the same with the expanding rubber.....:cool:

We used to have similar expanding plugs to use for field repairs on firebombing aircraft when they had leaking oil coolers. The Douglas A26 go back to the 1940's so the principle is much older than we are. :wink: Someday someone will unearth an ancient tomb someplace with something similar in it. :glasses-nerdy:
