I just purchased a 3130 head, and I'm very happy with the smoothness - even at high magnification, the motion is pretty smooth. However, the locking mechanism does not lock down the plate firmly. It's clamped enough so that there's no worry about losing the scope, but there's definitely a fair bit of "jiggling" going on. Disappointing. It jiggles whenever I touch my scope, say to adjust the focussing ring (FSIII ED82-A). I see there is a hex screw on the locking mechanism running through the axis of the cam that clamps onto the quick-release plate, but it already seems pretty tight, so I didn't want to force it.
Anyone run into this? Any suggestions for how to firm it up? Did I get a defective head?
Thanks in advance.
