Soft Jaws and Nova chucks

[hughie]

The large Nova bowl jaws come with additional m6 tapped holes which make then ideal to making soft jaws.
Turn up a plastic disc to matched the close diameter of the jaws. Now before you place it in the jaws fit into each tapped a a locking screw upside down with the cupped end just protruding the through the surface. Insuring its tightly grabbed in the jaws, then gently hammer it to allow the locking screw to mark the plastic. Dont for get to mark the jaws number of the plastic. The take it out drill clearance holes etc and cut into 4 pieces on the bandsaw. Return and what ever dia you require in the plastic jaws. You can use any soft material nylon , wood , ply wood etc

Alan Stratton describes an alternative approach in his video DIY soft jaws. The primary difference being direct to the chuck body versus connecting to Cole jaws. I have done neither so can’t opine on which might be better.

I looked at direct connection, it involves more maching with a fairt degree of accuracy. Then I found Nova jaws come with pre-tapped m6 holes, so it became a no brainer. The only catch is they [Nova] have changed the PCD of the holes so that the new soft jaws are not interchangeable between the two sets I have.

I bought a couple of sets of the Nova soft plastic jaws that attach to the chuck. Attach, turn as desired.
