Oiling Spring Airguns

 

By Russ Best

 


A notable portion of (magnum Springer) power is developed via "lean burn ignition". Lower powered Springer’s operate in what Gerald Cardew called the 'pop-gun' phase. This phase is described as not having any combustion occurring...the gun operates on the air it compresses when the piston rushes forward. Guns who develop added power via some light combustion use very little actual 'fuel' to obtain the necessary velocity.

Both RWS and Beeman say that only a couple drops of chamber lube be used for every thousand rounds (or more!) WHEN the piston seal starts squeaking! Over use of these specially developed lubes has accounted for many damaged guns...many of them with voided warranties because of the excessive use of chamber lubes.

These lubes were originally meant for use in guns that had LEATHER piston seals to help keep the leather pliable and sealing properly. They really do nothing for guns with synthetic seals except detonate.

This brings me to the term 'diesel' again. There is a difference between dieseling and detonation, and detonation is dangerous condition. It's usually seen when highly combustible lubes are used in a gun. The gun produces a very loud crack when fired and may or may not exhibit smoke coming from the bore--the amount of smoke depends on how fully the lube was burned, they type of lube, etc. Detonation can occur even when NO smoke is visible afterwards.

It can break springs, cause compression chambers to swell, and generally endanger the shooter or anyone else nearby.

Most springers made now (at least in Europe) come lubed from the factory. AA, BSA and HW most notably. They no longer require ANY user necessary lubrication, as they are well greased inside. Because of this, Beeman is no longer ordering Chamber Lube (and a few other lubes they were selling) because owners will only abuse these potions and damage something. They are no longer needed in quality modern airguns.

As others have already pointed out, what (some) are promulgating as a restorative process (Liberally applying various brands of low flashpoint lubricants to the interior of the airgun) is actually dangerous and foolhardy. These added lubes reduce the guns ability to shoot with consistent accuracy, and it also will have an effect on the guns longevity (if not the shooters!).

In the interest of safety and keeping your airguns healthy, I strongly recommend that no-one follow this 'restorative process'...or anything that remotely resembles it.
