I recently picked up a Calumet CC-401 camera, but the locking knobs for the front and rear tilt never worked properly and the washers under them seem to be disintegrating. I'd like to replace them and hopefully then be able to lock down the camera.
Does any one know what materials I should use and where to get it? There is a black foam-like washer and another rubber (?) washer with a cork-like appearance.
