I've read an article about it in S&T (about 15 years ago, don't know exactly because I lost almost all my S&T issues). The builder had made its Dob (he named it 'Christine') and the mount itself out of dark tinted wood (mahogany..?). It was a very nice looking scope. The consept is very easy : in one position the scope is a regular dob and in the second position (you have to delicately hit it with your foot to tilt the mount)it is a true Equatorial mount. Never understood why he made this odd looking scope. But I think it deserves it's place in this list of mounts. I think it will not ever be build again, but still it is a nice looking mount. Still It is a very easy to build mount. The angle of the wooden base is the same angle as your latitude. To use this mount for larger scopes I think the lower disk(at it's edge) of the rocker should be supported with ball bearings, I even think it is a necessity. Usage : 1- Small to large telescopes. 2- Reflector (mostly Newtontelescopes). 3- Transportable. Years ago I made one myself to be used for smaller telescopes for our youngsters at our observatory. I thought it would be fun to use these mounts. I had to stop this project. I think I have this little mount somewhere in a corner of my workshop collecting dust. I'll see if I can find it and post a picture. To be clear, mine has never been tested, pitty ...

Got me thinking about progressions to the design. :-) Post Extras:       Chriske Kijkerbouw Urania Reged: 08/15/04 Posts: 1953 Loc: Boechout, Belgium Re: DIY Mount - Dual purpose mount [Re: Glenhuon]       #2571782 - 08/10/08 09:54 AM Edit   Reply   Quote Quick Reply   Found my prototype... ! Tons of dust on it... It was intended to be used for a small scope 130 mm f/9. But like I said, never finished it. -------------------- Chris Post Extras:       rmcpb Carpal Tunnel Reged: 11/16/04 Posts: 1568 Loc: Blue Mountains, NSW, Australia Re: DIY Mount - Dual purpose mount [Re: Chriske]       #2572882 - 08/10/08 07:10 PM Edit   Reply   Quote Quick Reply   I had a play woth a dob wedge mount and came up with something similar even down to the extra bearings to keep it going Great series of articles BTW. -------------------- Rob 8" & 13" Dobs Equatorial Platform Couple of Panoptics and a handful of BO/TMBs 9x60 binocs Post Extras:       Chriske Kijkerbouw Urania Reged: 08/15/04 Posts: 1953 Loc: Boechout, Belgium Re: DIY Mount - Dual purpose mount [Re: rmcpb]       #2573736 - 08/11/08 06:20 AM Edit   Reply   Quote Quick Reply   Thanks.
