Ok there must be many links somewhere to how to make a dob mount, I have decided to keep the scope I have just bought (tube) 6" skywatcher and make a mount for it so that it can be used by people who want to borrow it but can not afford a scope.

Here it is in photo

I paid £65 including electronic focuser (made an offer and got it)

There's a design here that looks as though it can be made to fit a variety of scopes, including a 6" f/5 OTA, which is what I assume yours is.

http://www.scopemaking.net/dobson/dobson.htm
Scopes: Meade 8" SCT, Skywatcher 127mm Mak, Raffle winner of SW ST80
For imaging: Pentax K5, Asda webcam, Star Adventurer (new toy)
For companionship: Mid Cheshire Astronomical Group.

That is the classic homemade wooden design.
Here is another variation.

Basically it is a box with a circular cut-out on the top. The telescope rests on the cut-out via a circular trunion which is attached to either side of the telescope tube. The diameter of the trunion is determined by the weight balance of the 'tube'. It needs sufficient friction to be held at the desired altitude without slipping, but no so much that it cannot easily be altered by hand. The cut out and/or the trunion can be lined with plastic or some other material to give the desired friction.

Azimuth movement can be achieved with a turntable arrangement on the bottom.
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC and Canon 500D for imaging.
