Auction text: Selling a MKIV Fullerscopes mount:
Fullerscopes MKIV telescope mount | eBay
______________________________________________________
These are absolutely dreadful auction images considering these are intended to sell the object! Inexplicably photographed in a very dark place. I have brightened the only two auction images worth copying and have increased brightness, contrast and sharpness considerably.
Some sort of secure cover in a permanent outdoor set-up is very desirable. Not necessarily in a formal observatory. A secure, waterproof box on a permanent pier would do. A sack truck could be used to move the mounting on a low pier. One which is stored in a garage or shed with a smooth threshold and hard surface. A tall pier, for a refractor, would require large, sturdy wheels and a smooth, hard surface to run on safely without tipping. I speak from years of experience using the MkIV on various pier heights all of which are endlessly sinking into the lawn or gravelled parking space. Just lifting the bare MkIV onto a pier working alone is hard work in itself. Anything which makes set-up difficult will mean an instrument is hardly ever used.
Manual slow motion to the Polar axis only. [Assuming the worm is still usable] Beacon Hill could supply new worms and wormwheels, drive motors and controls. While AWR has long experience of offering very sophisticated, stepper motor drives for the MkIV, including smart controls and Goto. There is really no need to replicate the original 6" Fullerscopes ring-type wormwheels. Changing to larger wormwheels of [say] 8" or 11"/25cm would allow smaller drive motors with higher accuracy. All without having to resort to drive belts to get enough torque from large stepper motors. The MkIV would make a good base to practice improved bearing types over the original, plain, bronze collars. Taper roller bearings or ball thrust bearings would reduce the torque requirements on the polar axis drive if properly applied.
