Suggestion for a new base for 12" Skywatcher OTA

[kirkster501]

Hi all,

I demounted my Skywatcher Goto 300P years ago.  I have the original mounting ears on the side of the OTA and replicated the original Skywatcher 300P base (the goto uprights are different between the goto and the manual).  However, I get lots of slip and stiction in the vertical up/down axis which makes it a pain to use which is a shame since it is a lovely scope optically. 

I am thinking as a winter project to completely rebuild the base for this OTA from scratch and was after some ideas/inspiration guys please?

Have a search around for some of Moonshane's threads, should get some good ideas from there.

This Sky@Night magazine article has plenty of detail;

Although it covers all aspects of making a Dob, this book is considered a bible: https://www.willbell.com/tm/dobtel.htm

If you decided not to make it yourself you're only a stone's throw from David Lukehurst. https://www.dobsonians.co.uk/

The key tool in Dob making is probably a router which will allow you to cut good circles for the Dec bearing.
