If your Dec or Ra axis is stiff when rotating with the clutch released, you can adjust this ( tighten or loosen ) as well to make balancing your rig easier

Thanks Martin,
I didn't see Roger adjusting my NEQ6 Pro mount but he told me
that he had a special trick to do it.
He put it on a pier mount and attached a 3 meter long metal pole
to the mount top bracket.
He then checked the play by moving the pole up and down.
He used one Tally Ho cigarette paper - the thinnest they have -
to insert between the worm drive and the worm -
the idea was to adjust it till the paper just started to grab to
find the closest point where the gears wouldn't bind.
There are adjustment screws to do that.
It seems to me that it takes considerable experience to do the adjustment
since he got it right first time.
cheers
Allan
