kind people. I have sold the base for my 12" dob, but find that I need a dimension. I need to know the distance from the ground to the az pivot point. I have marked the distance on the attached photo - the blue line, please. To the nearest cm will be fine, thanks.

Hi,
Mine is a Bintel but it should be the same - 63 cm.
(Edit) Whoops, hang on, I forgot I have a lazy susan bearing in there, which will have raised it. If no-one else has the measurement I will work out what it was in stock condition.
Cheers

Reason: Mistake
Geoff, you're a hero. Yes, it is (was!) a Bintell 12" dob. So - 63cm from the axis of the Az bearing to the ground. The bearing might have added half a cm, if that - you would have taken the teflon pads out and replaced with the bearing?

Just been out for another look using a spirit level and vernier calipers. In the standard setup it would be a millimeter or 2 over 62 cm.
