Cg5 question/comment new
      #5846403 - 05/07/13 07:14 PM

Hi,
I just bought a cg5 and I am so far very happy with it. That being said when rotating on the Ra axis one side is so tight that even when completely unbalanced and unlocked it doesn't move swing or move unless I move it. I balance it on the other side. Any idea what this is? It doesn't affect traking or goto.
Also, I think that it is more clumsy to carry than the svp mount. The svp mount has a leg right in front of due north so it is easy to carry it with the counterweight. The cg5 has its legs on either side of north (I guess nw and ne) when picking it up the weight makes it quite heavy.
I hope I've described clearly what I've experienced.

On the top of the tripod, before installing the mount, there is a pin that is screwed into the top. If you unscrew this pin and screw it into the other hole on the top, the counterweight shaft will be positioned over the "north" leg.

Mine is tighter on one side s the other too. I've not gotten to taking it apart to investigate yet.

And I second Mike K's comment about the azimuth peg. Easy to move. I guess it works better the way it is shipped if you are a low latitudes. I reversed mine so the north end is over a leg.

The stiffness is probably due a poor fit of the worm wheel/clutch drum in the RA housing casting. If it doesn't effect tracking (it's locked in place when the clutch is engaged) it's not critical. Makes getting the balance right a PITA, but the solution is a tear down and lapping it to a good fit.

I've seen them so bad they can't be separated without 30 minutes in the oven.

This is the most common issue with mounts of this basic design. It is a fit and finish issue that can be minimized to a great extent on the RA, but requires complete disassembly of the mount to take care of it.

Hi,
Now I can say that I'm very happy with the mount. It tracks well. I had Saturn in it for a couple of hours. The Ra is VERY smoothe now. I guess it just had to be used. I am happy with the purchase.
