Lubrication for Honden (Grizzly G0731) Mill Leadscrews

[Dave022]

I have taken my mill apart for a quick paint job and clean up. The manual says to use NLGI #2 grease on leadscrews. Initially this seemed like a bad idea to me as I am not keen on using anything that can trap chips on my machine tools....

However, they are pretty inaccessible for oiling and well protected; in addition I never use air to blow off chips. I scraped off a thick layer of grease with no visible chips.

If I do use grease; how much do I use on a leadscrew?

What are peoples thoughts on the use of Teflon dry lube?

I use an acid brush and paint on the width of the acid brush into the gap between 2 threads.
This will get smeared around as the screw does its thing.

Realistically, you only need enough that all surfaces have a thin coating at all times.
