Thread lubricant?

[jimgalli]

Thinking about this some more after DE brought up lubriplate. At work I have dozens of movie magazines that I am in charge of. They hold 1200 feet of 35mm film and are opened and closed with a thread. Picture a 12" disc with threads. Well before I got there some %*&(_() sob lubed them with lubriplate. After time, that stuff turned to (sitting several seconds trying to think of an adjective to describe this stuff....). Anyways it ain't nice and I have a devil of a time to this day with a few of them. I cleaned them with pencil lead. Sharpen pencil, put deep in thread V and rotate with pressure until the dried up goo is gone. Pencil lead is graphite and actually leaves a very dry very slick residue. Most of my big lids can be spun effortlessly now. Give it a try. Can't beat the price. Most of my pencils are stolen.

Thanks, guys. I'll try a through cleaning first.

Graphite is a powder and will always remain a powder. It is very stable and will find its way into places you don't want powder, such as between elements, onto film, etc. I have been very successful keeping graphite away from any of my lenses.

Yes, if you dump a large quantity in a lens you will have problems. The key is to know what you are doing: get the finest graphite you can find, put a tiny amount in the lid of a 35mm film cannister. Take a Q-tip and roll it in the graphite. Apply it sparsely with pressure. Take several other Q-tips and clean off any visible graphite. Now you are left with graphite particles in the pores of the brass.

I just repaired a cine lens (I'm a lens tech in the movie biz) and employed this method. Works great. I'll have to try the pencil trick! Thanks Jim...

On the other hand, there is a stable lubricant which stays put and is very readily obtained, and that is Lubriplate. It is used on automobile engines

That would be a big mistake. As pointed out, that will eventually gum up and make a huge mess. The key term here is "automobile engine"--keep that stuff away!

I have lens grease from Zeiss, Canon, and Fuji. They are very specialized--and you won't find them on automobiles!

For the former that may be true, which is good to know because according to Nietzsche faith ain't going to get it:

A casual stroll through the lunatic asylum shows that faith does not prove anything.

HenceForthWith that is a great signiture!

As for the question I agree with a few of the others: get it clean, keep it cleanand carefully remove any burs. Teflon tape would be good if you wish to seal the air inside, but probably would not otherwise be helpful.

Thanks--I did philosophy in college and have been reading him ever since. It isn't easy reading and I don't agree with everything he wrote--but on faith, I'm with him 100%...
