I am not a handyman at all, but a good friend of mine has given me a lot of scrap that hasn't been used in decades, and I determined to make a decent planetary telescope out of it (primary mirror is a 10" f/7).
The equatorial mount is the part that most intrigues me, the first picture shows it as I got it. Now it is disassembled as I am cleaning it, and it already looks much better (legs are already off in the picture). I wonder if anyone can identify this model? It has no maker's signature, no sign that it ever had setting circles, and seems to have been heavily modified by a previous user (lots of old electric stuff in the pier, and power outlets added). Polar and Dec. shafts' diameter is 1.5", and there are no counterweights; on the dec. shaft there is a small threaded hole towards the end, but I don't know what it is for.
I once plugged the motor drive to see if it still works: big flash and loud bang, lights out.
OK that was not too smart. The wires' insulation is worn out and so there was a short-circuit, outside of the motor I guess. Another problem is that some screws or wing-nuts are so rusty, corroded or whatever that I cannot turn then just by brute force . Any suggestions on what I could use?
Thanks a lot folks for your help!
