Spring Gun Tuning

[IainMAD]

I have been recommended red lithium grease to use instead of Molly.

Has anyone a view on this.


Many thanks

Really great thread, I've not taken a gun apart for nearly forty years. Great reading!

I have never looked into red lithium grease for lubrication duties on springers so couldn't say for sure. However, moly is proven, plentiful and not expensive anyway (especially for the very small quantities needed), so I would say stick with what we know works.

Its all about what to use where.
Moly paste is great for lubrication of metal-to-metal surfaces, like the rear skirt of pistons without synthetic bearings.
On synthetic spring guides, other lubes can be good, I prefer PTFE containing greases on tight guides.
Thicker tacky greases like I suspect your red lithium grease may be, can be used sparingly to reduce vibrations when guide-to-spring fit is sloppy.

I'd stick with moly.

red lithium grease is used to stop the twang by blathering it on the spring

Great thread and many thanks to all for the great tips and advice.

I have spoken at some length with Tony Leach about the best lubricants and he recommends a tiny amount of silicon oil+STP blue+WS2 for the inside of the compression tube of HW77s/TX200's and other sliding compression tube airguns.

For standard spring guns a smidge of STP blue+WS2 is good for lubricating the piston seal in the compression chamber.

For metal to metal a light coat of high moly paste(50% plus)/light grease is a highly recommended option.

Tony Leach makes a very good point of advising against super thick greases where tolerances are close(such as the inside of the spring guide) as the grease may grab and cause inconsistent/low velocities.

Well supported springs do not need masses of heavy grease.
