I swear I am chomping at the bit just waiting for it to get slightly warmer in my garage. I really want to do get started on this restoration. But it's still extremely cold that my kerosene heater just can't keep up. In the meantime, I'll keep asking questions as to which way to go.

I do have a couple questions. Does anyone know what the original paint was? Gloss white is close, but did Criterion have one specific paint supplier that had a certain paint code?

I think it is a bone white color. When I did my RV-6, I painted the tube with Rustoleum Vintage White, it gave a more cream color, very similar to the color of the Cave Telescopes.

I used Rustoleum Appliance Epoxy Biscuit color. I really like it. The paint dries rock hard. I painted mine a rotating rig I made and didn't touch it for at least 2 weeks or more. If you belong to the Yahoo Dynascope Group, I have quite a few picture there of both my RV-6 and RV-8 restorations. Link to the RV-8 file that shows my paint set-up. Mr Magoo's RV-8 Dynascope album

One shot of my OTA in the paint booth on the rotating rig. Not sure if you can tell anything about the color. It almost matches the original aged color on my RV-6 tube. Rotating it while painting and drying makes the paint come out like glass.

I took a bath with big red this evening. This is the scope in the Christmas tree stand I posted at Christmas. Its legs vanished when the previous owner moved which is why I was using a tree stand.
I'm cleaning it up to use but its too cold to wash outside, the tub seemed like a good idea.
The red is going to stay for a while I like it. I will strip the red from all the parts except the tube. The red is on everything. When I was in high school there was a shop that would paint your car any color and guaranteed not to fade for $99. They would mask the glass and the tires and shoot the whole car including you if you were standing too close!

Nice shade of red there. Just curious, how much would I be ridiculed if I decide to change the color of the tube? I'm thinking gloss black with white lettering.

Robert, were you thinking of Earle Scheib? They painted my dad's 53 Chevy when I was a kid. It had been black (original paint) and he was tired of the color. He took it in, the car was probably 10 years old, he picked out a blue and when he got it back it was this god-awful turquoise color. He took it home and he was so p.o.'d. Me and my mom had to clean the paint off the tires, chrome, etc. from the overspray with rags and paint thinner while he raved and drank beer! It was kind of comical in retrospect.

I hated that car. I learned to drive in it. It had a 3 speed, column shift transmission, no power steering, and no power brakes. My dad had zero patience in teaching, had been in the Navy and swore like a sailor. It was an experience to say the least. The thing drove like a Mack truck!

Earle Scheib, used to advertise on TV, "I'll paint any car for $29.95.

Yes thats it Terra. A friend of mine had his VW bug painted yellow and like you said all the trim, hubcaps rubber moldings everything was painted. I think even the lights were painted if I remember correctly. Fortunately though the VW Beetle is probably the only car in the world a paint job like that is acceptable, my friend didn't care he thought it was groovy.
I miss my bug and I miss burning converse all-stars in the morning. Your feet would burn while your face was frozen and the windshield was totally fogged up, but I loved that car.

Rob black would be awesome. I don't see why not since you need to paint it anyway. White letters?

Gosh Robert, you are right, there was even paint on the headlights! It was everywhere. My dad was fit to be tied! And those old VW bugs were cool. I never had one but I had several friends that had them back in the day, so I rode in them and periodically drove them too. My dad used to say they were powered by a rubberband. :lol:

Rob, I like the black idea too. I'm building a 6 inch F10 this summer and I plan on having a rolled and riveted seamed sheet metal tube made for it at a local HVAC place and then painting the tube gloss black (flat black inside of course).

Rob, you might consider the Rustoleum Vintage White like I did on my RV-6. Looks really great.

When it comes time to strip the paint, buy a bag of wood shavings. They sell them for hamster bedding. Not sawdust.
Let the stripper soak in, then grab some shavings with a rubber glove, wet them with solvent and scrub off the paint. Just discard it when it gets sodden and grab another handful.
a Rag wet with solvent wipes off the remaining softened paint and any stuck on bits of wood shavings leaving it nice and clean. less damage than scraping. maybe overkill for fiberglass.

I need to paint it eventually. There are chips and small cracks in the tube. Every RV-6 that I've seen pretty much has been painted white except for your red. I'm just wondering what black would look like, and if I would be maimed and/or killed for my sacrilege.

I can't wait to see the build thread on this one Terra. What are the other specs on this scope?

I've got one of these fine scopes, too. My mirrors are visiting Majestic, right now, but should be back soon. I'm wanting to spruce up the paint; but I thought some trim rings might dress it up even more. Do any of you know where I might find some to fit? My scope will be 36 years old this summer ! P.S. I'm trying a gray color paint from PlastiDip - hoping it won't show my finger prints so much

The tube ending trim I got was called Car Door Trim from Autozone. It's a black vinyl. It works very well and looks nice.

Anyone have any idea what the markings on the mirror mean?
Here are a few examples:

Mirror #1 motor date 2-74
50.2 (on back)
Null figure (on back) (Null is a circle with a line through it)
1.MM (on back)
CMCO (on back) (Criterion Manufacturing Co.)

Mirror #2 motor date 1-75
50.250 (on edge)
+.5 (back)
CM (back)

Mirror #3 motor date 7-79
1065 (scribed on back)
Null figure (on back felt pen)

Mirror #4 motor date unknown
50.025 (on edge)
+.050 (back)
CM (scribed back)

50.xxx is focal length. CM and CMCO is Criterion.
What is Null, +.xx, 1065, 1.MM, anyone know?

I checked the back of mine and it only has the focal length - '50"' and nothing else. I think DavidG knows what the +.xx marks are - something to do with the deviation from f/8 or maybe? I remember someone posting about those RV-6 mirror markings a while ago, but can't find the thread...

Mine has 50" as well scribed into the mirror, no other markings I could find.

Why not make them???

Here's an idea for some inexpensive tube rings I made for mine. They were extremely easy to make and are completely reversible to go back to original. Check out the 4th page. Great scopes by the way.

I now understand why the legs came with black wrinkle paint. It's to cover up all the casting flash and machining imperfections! I started stripping the paint and these legs are a complete mess. I'm going to try to smooth everything for paint but how much material can I sand away and still retain the strength?

Scott, your scope looks better than new. My mirrors came back 2 days ago; and I'm anxious to just put everything together so that I can observe again; but seeing your work makes me feel that I should spend some extra effort.

Scott does beautiful work. I especially like his tube repair technique in that thread.
Rob the wrinkle black can sure hide manufacturing marks and etc. I think most are unpainted. I would be tempted to fill the imperfections rather than remove a lot of metal.
I overhauled my focuser today. Very nice unit, cast iron and brass, precision and square to the tube.
I was lucky I could remove the red paint from the focuser without attacking the wrinkle black. I even have red on my diagonal mirror! Earle!

The RV-6 focusers are nice, but I wonder why they used cast iron? They're kind of heavy!

Its heavy but it does tend to counterbalance the tube with the mounting rings close to the middle which is nice.
The focuser is great I like it. It reminds me of the 40's technology rather than 1959 when the RV-6 was introduced.
The Dynascopes used something very close looking, not sure if it was cast iron.
I don't see how the RV-6 focuser could ever wear out I don't think it would be possible.
