Anyone know if they changed the design of the Supanova chuck before coming
out with the latest version? (NB, I do mean Supernova, and not
Supernova2). I just looked in the manual -online at:
http://www.teknatool.com/products/Ch...upermanual.pdf

and where it says there should be a 'Travel stop screw' to stop the jaw
slides being unscrewed to far, it ain't there.


Both mine have them, and it's a weird little beggar, so if you want the
memory aid, you'd have to get them from a supplier. It's supposed to
protect you from yourself and the company from your lawyer, though if you
always use a mortise, the piece will hold the slides from unwinding. For a
tenon you could get some inertial unwind, so if you use them at max
expansion rather than minimum, which is most effective, you might get into
trouble before you feel the piece wobble. Especially with something like
Cole jaws.

Watch that little bugger. As Bill says, it's deliberately in the way, so
when you open to eject dirt and add lube, you'll often forget and be
cranking and cussing about why the jaws won't thread out. DAMHIKT
