Apparently, this was made by a person who worked at the Adler planetarium in the 70s. Picking up later this morning. 

Will be interesting to see!

The Adler had a mirror grinding workshop in the basement where anyone could come in an use it to grind a mirror.  I remember watching people grinding away during visits in the 60's.  I think the workshop was open well into the 70's, but it was closed after one of their major remodeling efforts.  Do you know that the scope was made by someone who worked for the Adler or was the scope made at the Adler by a member of the general public?

 

It looks 100% original.  That was the way ATM scopes were built in the 70's.  Very cool.

That is indeed very cool.  I love the pipe-fitting mount.  Can't wait to see more pics and find out what he used for bearings.

Typically on a pipe mount the threads are the bearings.

Not necessarily, IIRC, Thompson's classic, "Making Your Own Telescope", there were instructions on building a pipe mount where the pipe fittings served as shaft housings and the builder was shown how to pour babbited bearings for solid steel shafts.

I have a pipe mount that has poured babbit, and another that runs in a babbited clamshell.

I made several mirrors in the Adler optical shop back in the day. Typically the shop was used to do the "optical" portion of the build and the mounting and mechanical construction on your own. Was going to try the pipe-babbit bearings myself back then on my first scope build, but a master machinist and die maker intervened. (Thanks Dad.) 

 

Looks like an interesting scope. Any markings on the mirror?

I made a mirror there in 1970 (a 6" f/8 - I still have the mirror), my first. The optical shop was run by Ken Wolf then.

Later, Jim Seevers and Dan Joyce ran it.

 

And yes, it was closed, they were adding a 5 million sq. foot addition, but closed the optical shop because

they "needed the space." Idiots.

Still have several of my mirrors I made there (including the 6 inch f/8 first, a great setup. Ken was a good teacher), and yes I remember Ken and Jim both. See Dan all the time at CAS meetings. OK ... back on track. If there are markings on the mirror. I believe Dan still has the old optical shop records if you wanted to find out more details.

I got this story 2nd hand so maybe someone here has 'first' hand info. The Story... It was announced that the optical shop would be closing 'temporaly' for remodeling. Then on one weekend management cleaned everyhing out of the shop and deposited it all in a couple of dumpsters. When some who worked in the shop found out about this they hurriedly went 'dumpster diving. They saved what they could and took it down an Indiana club. Sounds awful enough to be true!

Any Indiana club is likely going to be the Wasbash Astronomical Society. Some one there would probably remember if it was their club.

This reminds me of the way Chicago politics closed Meigs Field.

One day in operation, then, through the night, holes were dug in the runway....

Next morning, history to a wonderful lakeside airport.

Unfortunately, after meeting with the seller at his work (my wife and I were down to Chicago anyway for a mini-vacation), I did not purchase this scope package. The eyepieces appeared to have fungus (especially the Brandon), and since I was sending it to a friend I just didn't feel comfortable with it. I am happy I was able to view everything in person, and just consider it one of my many astro learning experiences.

Sorry it didn't work out for you Steve. Sometimes things just look better in pictures and/or in our imagination than they do in real life. The hunt continues! ;)
