Thanks Andrew. The above video was all that was needed and 20 minutes total.
Not worth a new thread however I note the centre bolt that holds the two base plates together with with large bearing between, unscrews itself when rotating anti clockwise. It unscrews itself to a point only where the rotation becomes very easy to rotate with little friction in movement. Is this normal for a dobsonian or is a dab of locktite or similar needed on that bolt?
Cheers!
......... And as predicted, clouds tonight!
