Subject:
Nova midi chuck problem

Mike Cunningham (Cape May NJ)
>I have a question regarding a Nova Precision midi chuck and hope someone has an answer. I own a variety of chucks and seldom use this Nova so I have little familiarity with it. The other day I mounted it on the lathe and found that I was unable to open the jaws using the tommy bars, nor was I able to close them.

I looked at the Teknatool website and following the directions disassembled the chuck, cleaned and attempted to reassemble. The directions state that one should insert the #1 slide into the slideway which has a small half moon shaped dimple. I'm unable to discern this shape on any of the slideways. I've tried inserting the slides in numerical order starting at all four of the slideways and find that the chuck will not function regardless of the slides used.

Any ideas?

Thanks,
Mike
