<p>Hi All, <br>
I'm having a problem with my Arca Swiss B-1. I've had the ballhead for about 15 years and have always had problems with freeze-up. I actually haven't used it all that much in the last few years, but did today, and its frozen. This time, however, the main knob is frozen. Won't move in either direction. I tried using a set of pliers on it, and only succeeded in moving the rubber around the knob. Any suggestions on how to fix?</p>
