Finally finished the 1986 basket case Questar OTA. The OTA is pictured on a 1974 fork mount which is in excellent shape. Tested it out and everything is perfect from the collimation to the feel of the control box switches. Still working on the 1986 fork mount... I doubt I'll ever do this type of full restoration again!

Thanks. I'm still working on the forks which gave been a real challenge since they're in pretty rough shape. Here's a before and after of the base. It took a few rounds of wet sanding and polishing wheel...

For polishing metals, I have had great luck with Maas. Recently restored a vintage rosewood Herman Miller Eames lounge and the legs and support brackets didn’t look much better than your case in the pic above, and it worked quite well (possibly to alleviate any need for wet sanding).

Just a thought...

And I’ll second the comment above: great effort and great to see the before and after pics.

This is how the optics and eyepieces looked when I received it. The 32mm came out good but the 16mm is toast! Primary was clean with no fungus. All the optics cleaned up well with no coating damage or etching.waytogo.gif

Thanks. I was worried it wouldn't clean off but very relieved when it did! It's an excellent optic with typical Questar star test. Such a smooth figure the diffraction rings look like they were airbrushed.

I did this with a Questar someone had shoved in a closet for 7 years, after it had been wetted by dew.  Was a mess, mold all over and inside.  Luckily, none of it was permanent.

Fantastic job! Restoring these high end Maks is a lot of work and one can feel one is getting in way over our heads choosing to take on such a project. I did the same thing with a Quantum 4 many years ago. The scope was a complete disaster when I got it, wouldn't even focus when tube was tilted upwards. With some guidance from Alan Kerro the former production manager at Optical Techniques I was able to completely disassemble and restore including totally repaint a Q4. The project took me nearly a year, and just like you I told myself I'd never take on such an endeavor again. Photo of completed Q4 below. Once again, congratulations on tranforming someone's neglect and abuse into a real treasure.

Never say never again. It will be much easier and faster next time, now that you know how to do it. 

 

If one of your kids found a distressed Q 3.5 or Q4 and asked you to help them restore it, you know you'd leap at the chance to do such a worthy project together!

 

Really nice work, guys.

Totally agree on the "if your kids asked..."  There's a distressed Seven out there I know about, but I have no desire to spend months restoring another one.  Same for Cutaway (I have this fear that I'll find an owner of a 1954-55 "Pepsi" badge with original everything who offers to swap for my Cutaway).

Something a little new?  I'll bite every time.

Absolutely beautiful scope. I've had a couple of the Q4's and both have been excellent.
