Supernova travel stoop screw.

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:

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

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

Thats the problem!!! I'd like to increasse the travel very slightly to accomodate a bigger bowl, but since it ain't there to remove I'm wondering if there was a design revision.

Either that, or I'm being really stoopid.,,,

This was initially brought in to comply with European Union safety regulations, and is there to stop the cracked knuckles that you can get with engineering lathe chucks - and they HURT, as I have found out from personal experience!

The stop screw can either be found under jaw slide 1 or jaw slide 3. If the screw is under jaw slide 1 (as shown in the manual) then the jaws can be extended a little way beyond the body (about 3mm), but cannot be unscrewed completely. If it's under jaw slide 3 (European safety regulations mode) the jaws cannot be extended past the edge of the chuck body at all.

Mine came standard with the screw under jaw slide 3, but you can just take it out and move it as I did.
