Yesterday a reader asked why I bothered with Tune in a Tube. Why didn’t I just clean the Meteor Mark I when I had it apart, lubricate with moly grease and be done with it? That tells me there are a number of readers who don’t really understand what is involved with airgun lubrication. So today I thought I would discuss it a little.
Why do we lubricate?
This is a good place to start. In fact, from the reader’s comments, it seems to be at the core of misunderstanding. Don’t we just lubricate to reduce friction?
Friction is a principal reason for lubrication. But there is more to it than that. Sometimes we want to reduce friction by a certain amount, while retaining some part of it that’s needed for proper operation. Otherwise, moly (molybdenum disulphide) would be the answer to everything. Some airgunners think it is. The reader who wrote the comment that got me started on today’s topic said that very thing — that I should just clean the Meteor’s parts and lube everything with moly and be done with it.
