Restoring and Repainting Classic Telescopes
Posted 02 April 2008 - 11:00 PM
here is my refurbishing/repair of the declination-drive of my old â€œStausslike-GEMâ€.
As you can see in this thread :
The original setup was a tangent-drive with a spring-bolt.( a little bit swiffeling setup ). The base of this drive was made from acrylic-glass !!! After a few observing-session this material get a crack.
So I decided at first to make this unit completely new from aluminium. I have a lathe but no
milling machine and my friend who has one, was a long time ill.
So I made it the other way : from old ATM-parts I built a new declination drive with a worm wheel. Here it is.
Kind regards Michael

A question for you experienced restoration artists here: What do you do to revive the scuffed and dull aluminum (at least I assume they're aluminum. Stainless steel maybe?) C-clamps and trim pieces?

Added a bunch of upgrades(without altering the classicness).
This image and the one to follow is for all you *newbies* who are getting to restoring your classics.

It took 4 years to restore.

One of the hardest things to do when restoring a classic telescope is selecting a color to repaint the tube and trim. Essentially two routes can be taken - you can mimic the original colors as much as possible, or you can go in a completely different color(s) making the scope more an expression of your own personal tastes.
Over the years, I have tried to do both. Of late, however, I find myself leaning toward restoration of telescopes in the "spirit" of the original while giving the instrument a new lease on life.
My current 4.5" f/15 refractor was assembled from a pile of abandoned components from different telescopes with the addition of some DIY stuff to make it all fit together, so there was no "original" state to emulate. Therefore, I simply did what I thought would look nice, yet not violate the classic nature of the original instrument(s).
I could certainly have had the tube professionally painted or powder coated, but it never occurred to me at the time. So I settled for careful application of spray Rust-Oleum primer, metallic blue, and clear overcoat to get the effect I wanted. Cost was about $2.89/can for a total cost of around $25.

Can't answer your paint questions. Sorry.

Do you have a paint code for matching Brandon Sky Blue color?

Gonna start this one up again. I am currently in possession of the parts for a Towa 60/700 and a Carton 60/1000. I have already painted the Towa tube (Krylon Gloss White). I had it turning for 24 hours. I build fishing rods, and you have to spin the rod slowly while the epoxy on the guide threads cures. The motor I use is from Cabela's, and spins at about 4rpm. It has a lot of torque, so it had no trouble turning that little tube. With a slight alteration, the mandrel (homemade) was able to hold the tube from the inside firmly, and on the other end I built a spinning disc with inset screws with felt on their heads that could be backed out to contact the tube inside and grip it firmly enough to prevent slipping. So the tube was held on both ends, spinning at 4rpm for 24 straight hours, and the finish was perfect. Since I have been on the road since then, I expect the tube's paint will be cured completely when I return home. Can't wait to get it together, and do the same with the Carton.
That's the way to do it..... I rigged an old BBQ grill motor to rotate my 8' tube for my 6"f/15 when I repainted it.
I painted it while rotating, and let it dry rotating for a day as well.......
No runs, drips or errors. Images are posted on my website.

Body filler vs. spackle vs. ???. Primer and/or Krylon OK? etc, etc.

As for paint, lots of folks here use Krylon. Just make sure your primer is laid on thick enough. If I had to re-do my scope again, I'd pay a lot more attention to getting a more substantial layer of primer as even the slightest little tube blemish shows up when you apply the glossy stuff.

Here is a fine example of a telescope built around a vintage Zeiss objective lens. Mr. John Pons of North Hollywood, California stands next to his 10"F/16 refracting telescope. The GEM mounting system was built by the Edward R. Byers CO. in Barsto, CA. some years ago. Mr. Pons previously had a 8" telescope upon the same mount.
Chris, I'm not sure whether I should be upset that you hijacked my picture off the other thread, "Amazing Full Moon Star Party," to use here without mentioning where you got it from. To use a picture as your own is not ethical and against Cloudynight.com policy.

I had that same photo on my desktop for a while. But that is personal use and off the internet.
Regards and clear skies,
