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!
Yeh, I noticed mine did the same thing when I first got it, although I haven't noticed it doing it lately. Which either means it's 'bedded in' somehow, or I always subconsciously rotate it clockwise
There's a metal bush that the bolts meant to go through, it will be in the bag. It extends about 1mm extra between the base and main base and will be a brass or silver bit of metal tube/pipe.

Cheers, that bush is in. How this would stop the undoing of the bolt I cannot see. More investigating is needed and the end result I'm sure will be my first mod. Yeah!
