So who here has struggled with their brand new cem70 and found that after initial balance both in Dec and then RA in the horizontal positions you go back to zero position, disengage the clutch and the RA starts to swing either east or west before settling into the balanced horizontal position?
Sure, you’ve seen the YouTube videos describing 3d balance and how you need to add washers, elaborate clamps etc. heck I’ve done it, only for my sct to look like something out of mad max.
The fix is so simple. Now I did this with my gear all attached, and outside during the lull from the No'reaster but I think it's better done inside with no wind, and maybe no gear attached.
I loosened the two small grub screws as well as the top Allen screw and the side Allen screw (not marked on my pic) Gently adjust the RA counter weight bar either left or right with the clutch engaged, disengage the clutch and watch where the ra axis starts to swing. Repeat until you notice no movement East or west. The adjustments are tiny, so take your time! Slowly tighten everything up, constantly checking the balance.
Do this right and Voilà you now have a balanced mount on the RA axis that doesn’t require clamps on the counterweight bar or other contraptions.
If this is a retread of an old topic here on CN then I apologize. Quick video here
