helicoid lubrication

[laptoprob]

Been away from this place for a while, but what happened? Sooo many different forums... I could not find the repairs part anymore.

Anyway, here is the question. I had to take my trusty Steinheil Quinon apart to get the focussing back to how it is supposed to be. After a long time puzzeling I got the lens back together again (sigh...) but after cleaning the focussing helicoid it should get some new lubrication.

What to use?

Rob,
If you look at my website, there is a discussion on what grease to use in several of the FSU repair sheets. In short, use a fully synthetic based gease which doesn't "creep" or outgas. Preferably silocone based or if you do need something slightly thicker use a graphite based one. Do not use the ones for automotive use. Most of these are not very suitable.
