I'm a complete newcomer, so please be patient. In particular, I'd appreciate suggestions whether this is properly a new topic or belongs in an existing one ("More Edmund Scientific" seems a likely place, but more about the telescopes than the mounts). I did spend a couple of days browsing this forum and found tantalizing hints, and a wealth of knowledge, but not quite what I'm seeking.
A new neighbor found an Edmunds 8" reflector in a fence row when he bought the 80+ acre property. It had been outside for years and was scheduled for scrapping when I expressed interest. The 8" galvanized steel tube was crushed in several places, but the primary and its cell, secondary, eyepiece and finder are largely undamaged and usable or repairable. The primary is evidently about f/9. I'd like to show some of that later, but for now I want to sort out the mount. My eventual intent is to put the telescope in demonstrable condition and donate it to a local astronomy club. I'm an electrical engineer and machinist with a considerable workshop, and can make just about anything, but with limited optical experience and negligible telescope experience.
The mount resembles various ones I see in other threads at this forum. Its pier legs are the heavy duty ones, connected with two bolts to the pier. The head is an offset yoke, with provisions for a tangent arm. Its elevation shaft bore is 7/8 inch. There is no tangent arm nor driving screws. No casting number is evident.
The moving head has a single lug or tongue, much narrower than the gap between the head yoke arms, a 5/8 inch elevation bore and an adjacent 3/8-16 hole presumably for a locking screw in a single-sided mount. It has no provision for locking to a shaft as would seem to be necessary for the head trunion yoke.
The mechanism axles (right ascension and declination?) are 1" diameter. There are no graduated circles or pointers, but there are white disks that may have had a projecting pointer at one time between the castings adjacent to machined spigots where graduated circles might be installed. The two casting numbers are B-2089 and 612088.
The tube mount has places for four coplanar screws to pass through the wall of the telescope tube, rather than the (later?) cradle and strap method. Its casting number is C-2121.
I can provide any relevant dimensions as needed.
Here are my questions:
-Do these mount pieces belong together, or are they a mixed bag?
-Can someone point me to a manual showing a good parts diagram, so I can see what might be missing, and use the proper names for these parts when communicating?
