I have been the proud owner of the following telescope since 1988. I was living nearby the original owner when I saw it for sale. I used it a lot for about the next 5 or 6 years, and eventually used it to guide my Celestron 5.5" Schmidt camera, which I piggybacked on top of it. After about 20 years of not being involved in the hobby of astronomy, I have decided to dip my toes in the pool again. I have, in the past couple of days, begun dismantling the scope, mainly for the purpose of cleaning. Although I have taken reasonable care of it, after many moves and lots of time in a storage building, it's pretty dirty. And so, as you might guess, I have lots of questions.
Question 1: The ascension axis bearings are very sticky. To clean, do you remove them or clean them in the housing? After cleaning, do you use white lithium grease? (No grease on the bronze gears, right?)
Question 2: The ascension axis fine control shaft (is that the right word?) has a very small rolled pin that holds the worm gear in place that allows a slight bit of play in the movement. Is there a way to tighten that or do you replace the rolled pin?
Question 3: And this is the big one. Should I just get the scope going again or is this the type of scope that one should completely rebuild to "like new"? Is it an important Thomas Cave telescope or just "so-so"?
I'll provide any pictures any one requests, but keep in mind I have it in pieces right now.
