Question: using epoxy paint on cameras.

When blasting and refinishing steel wheels, the idea is to let them air dry for several days, then get the paint HOT, to 300 F for at least 45 minutes. If you can make a mark in the paint with the edge of a credit card, it is not fully cured. I don't know if the light bulb-in-a-box will get that hot.

I would only bake the painted metal parts this way; never the whole camera!

I have stated this before in a previous thread. When I worked in an auto factory paint shop, after top coat application or primer application, car bodies were sent through ovens at 350F for at least 17 minutes.

This type of paint was formulated to be dried in this way, spray paint out of a can may not be. All paint is not created equal. Painting a camera at home is kind of a crap shoot. Conditions can not be closely controlled.

I think that powder coating may be a very good alternative. Not everyone will want to pay a paint shop 35.00 or more to paint a camera that cost 20.00 or 30.00.

The old paint was probably lacquer. It sticks better, is smoother and has a brighter finish, is very tough, but good lacquer is very hard to find anymore (because of health hazards).

we talked about this once before so it got me to thinking (for restoring the older cameras that use this type of paint)....and i have been searching if its available etc

and i have found a place that may make/sell it here....i dont know how good it is yet or how close it is to what was used until the 50s but i am going to make further inquiries.

interesting stuff by the sounds of it, nitrocellulose based stuff invented around the early 20s from a resin of nitrate of cotton and other things, the solvents are toxic, volitile and flameable (so no need for a protective breathing mask and smoking is fine around this stuff ;)) .also the grade of nitrocellulose used to make the lacquer is much the same as nitrocliceran (spelling) used to make explosives. i guess for some reason the wimps prefer to make paint that is boring to produce and denigh the workers excitment and oppotunity to claim workers compensation!!!sheeze whats the world comming to haha

Oh, you can probably find a semi-tame modern version of it somewhere, if you look hard enough, but even then, especially if you smoke, I want to watch you apply it from about 100 yards away. It is very tough stuff though. In ancient times, the Japanese used to soak rice paper and silk in it and used it for making armor -- kind of a medieval kevlar.
 
Ah well in that case i will just have my kids try it first ;-) on a non favorite camera of course hehe... just to be on the safe side..ya know incase 'I' make a mistake ;-)

interesting history to it!

Maybe a non-favorite kid too, for that matter. That nitrocellulose lacquer is not the original formula either. Originally, lacquer was made from the sap of (believe it or not) the varnish tree.

Apparently the japanese are still using it to make armor: http://www.denverkendo.com/pages/bogu.htm Check out the breastplate.

it is interesting to see where these things origonated and how they developed!

after looking at that site and some further research it appears they began using that around as far back as 15th century ,,no doubt the lacquer 'Japan Black' (asphalt based) used in the early 20th century particularly by Henry Ford for his model T, took its name (if not some ingrediants) from that japanese finish. the 'Japan Black' (also called Brunswick Black) lacquer took 48 hours to dry (coloured versions up to 14 days; hence 'you can have a model T in any colour so long as its black') but it seems that type of laquer was ony used just into the 1920's (by the end of the 20's all but gone) and into the early/mid 20's the much quicker drying nitrocelulose formular (which as you mention has links back to the Japanese, korean and chinese) was introduced and was widely used in many applcations. so its reasonable to assume that the cameras of the twenties and most certainly the 30's-40's used this
 
My beloved Konica Hexar RFs came finished in semi-matte black epoxy, and the finish has proven quite tough, and, as a side benefit (IMO, anyway), warm to the touch. Perhaps he decision to go with an epoxy-based paint was connected with the exterior panels being made of titanium, but I think the result turned out rather nicely.

If you had the insides of the pistol cylinder/ chamber/ barrel coated, I hope you don't try to fire it. the tolerances would be a little too tight. that's the problem w/ powder coating on some things--it's too thick.

A great many of them did. It is a good deal harder than enamel, is shinier than all but the most high tech enamels (like Enron paint), it didn't need to be baked, and you didn't need to use a primer with it. It was just a very good paint, with lots of advantages -- but it would kill you really fast if you weren't paying close attention.

I believe it is still used to finish some of the better acoustic guitars; they just haven't found anything else that works as well.
 
I have personally used and can endorse DuraCoat two-part firearms finish from these people: http://www.lauerweaponry.com/duracoatcolors.cfm?colortype=stock&Category=220

I believe Brownell's also carries DuraCoat.

You do have to use an air brush to apply it (any low budget airbrush will work fine) and it's best to bake it for a while in your wife's oven at low temp (150 or so) after it dries. You can add extra coats about 10-15 minutes apart. I used three coats. Comes in several types of matte and gloss finish and a whole bunch of colors, some tame, some wild. It goes on and evens out beautifully, and dries to a super thin coat that takes a month or so to completely harden and cure at room temp. Even if you bake it (it doesn't stink up the house), it still needs to "cure" at room temp for several days (2-3 weeks is even better, it just gets harder and harder and tougher as it cures). But when it's done you will be lucky to be able to mark it with a pocket knife, let alone with normal handling. It was invented to coat firearms, and is heavily used in the gun world, It was so easy to use I can't wait to try it on a camera myself. I've refinished two beat up Gitzo aluminum tripods and a large aluminum and steel Miller video head with it so far, and the results have been simply amazing. Plus, it comes in a zillion colors, as you will see on their website. There might be other products that work as well, but I have used this one myself and can definitely vouch for it. Reallllly good stuff.
 
I am often intruiged by the black cameras (have a black Spotmatic) but wondered how one does the lettering so neatly, in white?

It's spelled "nitroglycerin." Incidentally, that isn't much of a surprise. Nitrocellulose is what they still make smokeless gunpowder out of. It is made with nitric acid and paper. They used to make it from nitric acid and cotton (guncotton). During our Civil War, or what we Southerners call "The War Of Northern Agression," they stuffed cannon and mortar shells with it. Add a little more nitroglycerin, and some petroleum jelly, dissolve it all in acetone and let it dry out and you get cordite.

On a humerous note, once there was a guy who made billiard balls out of nitrocellulose guncotton. According to what I've read, flames would shoot out of the balls if touched with a lit cigar and there was the occasional small explosion when the balls hit one another. Other than that, they worked fine. One Colorado saloon owner said he didn't mind the noise so much, but it was dangerous, because every customer in his saloon would immediately draw a gun.

Yeah, lacquer is not something for wimps. Oh, and BTW, unless it is a closed self-contained system, like maybe a Scott Air Pack, or maybe a rebreather, like an OBA http://en.wikipedia.org/wiki/Oxygen_Breathing_Apparatus a filter-type protective breathing mask probably would do no good at all.

Hi FallisPhoto,

While visiting Charleston S.C., we were touring one of the old homes down by the battery. The ladies conducting the tour pointed out some damage to some of the interior walls caused by shelling from Fort Sumter. They assured us that this damage had occured during the "recent unpleasantries". Being known to occasionally stir the pot, I asked which unpleasantries they were referring to. They replied "why, the War for State's Rights of course".

I have seen the paint sticks at some hardware stores and craft stores too.

Regards, Steve
 
Thanks for the paint tips. I will have to make some enquiries hereabouts (Australia) and keep my eyes open.

I noticed the DoF marks on a camera I am working on came off real easy when I was cleaning the lens barrel. Your comment on the use of wax only, came to mind.

Thanks
Murray

Yeah, "The War to Prevent Southern Independence," "Mr. Lincoln's War," "The War Between The States," "The Late Unpleasantness," ... I live here and I've heard them all. If you read your own state's constitution, ratified by Congress, you will, in nine cases out of ten, find a provision that allows your state to leave the Union. The Emancipation Proclaimation and a lot of the other "laws" enacted by Lincoln were not legal, since the executive branch does not have the power to make laws. The War, and a lot of the stuff that lead to it, was entirely illegal, much of its prosecution was performed in defiance of congress, entirely disregarding the existing laws, and a lot of the people here still get hot about it.

If you are ever in Richmond, stop by Hollywood Cemetery and look at Jefferson Davis's grave. There are DRIFTS of flowers there and he has four monuments. Unfortunately, when I was touring the cemetery with my camera and got to his grave, it was getting dark and none of the photos I took turned out well. J.E.B. Stuart's grave is also there and a mass grave for unidentified Southern soldiers. Both are still saluted frequently. The mass grave is topped by a really huge pyramid. There is a photo I took of the cemetery with the pyramid rising above the trees in the distance that should give you some idea of scale. http://fallisphoto.deviantart.com/art/Untitled-16235275

As near to an indestructible finish on small metal items as I've seen anywhere. Made for firearms, easy to airbrush. I've used it for brass, steel, aluminum, nickel, and stainless small parts, as well as several larger things like refinishing camera tripods and front panels and various parts of antique tube radios. Parts must be "roughed up" by hand with very fine abrasive (400-600) or bead blasted, and must be absolutely SUPER clean and grease/oil free, use medical gloves, no bare fingers allowed. Relatively easy to airbrush, 6-month shelf life, comes in about a zillion colors including at least a dozen shades/types of black. Initial cure is quick (dust free in a few minutes, cures to "ok to handle but don't bang it around" in a couple of hours. Clean up the air brush right away with lacquer thinner. Pop the parts in the wife's oven at low heat (150 or so) for 2-3 hours (fortunately it doesn't stink after the initial cure), then put the parts on the shelf for a month for final hard cure. Done. Have patience, don't rush the final cure, you will be sorry. A month is good, 6 weeks is great. The wait is worth it. Completely cured finish is difficult to even mark with a tool, let alone a fingernail or from casual handling or scrapes/bumps.

I must admit I haven't personally done a camera with it yet, but can't wait to try it, since based on my experience so far I think it will be ideal for that.
