EQ. MOUNT SOLD (THANKS JIM!), TRIPOD STILL AVAILABLE
This is an unusual item that might be just what you're looking for. First the tripod: It's heavy, solid, surveyor-style, and made of hardwood with a very thick metal mounting head. Adjustable from 38" to 70". Has sharp metal feet that really dig in, and would work well with vibration dampers.
The equatorial mount is similarly heavy. Shafts are solid and 1" thick. They go through what appears to be bronze bearing blocks, with large plastic knobs to lock the axes. Movement is smooth with no side-to-side play. There are two 7-lb counterweights with thumbscrew locks. [I'm told by an Astromart colleague that the "mount, counter weight and drive were made by Edmund Scientific. It was offered with their 6" f/10 reflectors as well as their 4" f/15 refractors."]
The RA axis has a 110v clock drive, powering a .5" worm and 3.5" drive gear. It works, but I haven't tested it for accurate speed. There's also a manual slow-motion knob in RA that engages the gear train. The scope cradle is metal with two rubber pads that go side to side. The curve of the cradle would exactly fit a 4" scope, but could work with anything from 3 to 8 inches with some shimming.
One problem: the mount runs into the tripod at very high or low latitudes...this mount/tripod combination would only work from about 20 to 60 degrees lat.
The whole assembly has that 1950 Soviet tank "feel" to it: lots of metal and wood, heavy and solid. If I had to guess I'd bet there was a 4" f/15 refractor attached to this at one time. [good guess!]
Asking $150 for the tripod and $100 for the mount, plus actual shipping charges. Paypal preferred. Thanks for looking,
