I just acquired a used Astro Tech voyager Alt-Az mount. The slow motion controls work very nicely. There are tension adjust knobs (screws really) for each axis. These screw have very little adjustment range and fall out completely after about 1-2 turns. A few times already, one of tension knobs dropped out on the ground.
So, I'm wondering if any others have run into this and found some solution? I need to push my refractor around on the alt or az axis sometimes for quick or coarse pointing, then use the slow motion controls. I'm not able to have a setting where the motion is smooth and also good holding friction. It would be wonderful to have something like the cam locks similar to Celestron CG-5 mount.
Over at OPT, I played with the Vixen porta-mount (alt-az). There was not a tension knob, but I could slew a telescope around very smoothly and the refractor would hold in place nicely and then use slow motion controls. I think there are set screws you can adjust tension with.
