Related clamp-repair topic.... on one of my ultraclamps I seem to have lost the disc connected to the screw that holds the clamp to a stand. Luckily it still worked on the flat wood surface I had to clamp to the other day, but no way will it stay on a stand like this. Any thoughts on a replacement? The clamp is inexpensive, so I could buy a new one, but...
I own 2 superclamps, one of the manfrotto table clamps, and 2 ultraclamps. Plus a Manfrotto 099B, a Matthews extension pole, a Manfrotto single articulated arm, and a Manfrotto double articulated arm. The arms in particular are key.
