Need some help, Ronford Sticks problem

[Rick Darge]

I have a set of medium-duty Ronford-baker legs. One of the wingnut knobs used for locking the legs was overloosened to a point where it felt like it was too tight. The wingnut was then turned counterclockwise with a lot of force. Now the wingnut is loose to spin in either direction, causing no grip to the legs. I think it's broke unless someone knows of an easy fix. It's difficult finding help out here in Tuscon for tripod repair.
