Re: [CAD_CAM_EDM_DRO] Re: metal/plastic lead screw lube

Ok, ahh have a 1 pound jar of teflon grease, the blue stuff. never even
thought about using it! duhh! we used it in the alternator/starter
rebuilding biz for high rpm bearing grease, and for certain pieces of
hardware one being steel screw into zinc/alum casting. Mixed with
never-seeze for brass bearings on small starter armatures since some turn
25,000 rpm. also is a good dip for mig welder tip if the standard tip dip
isnt available. thanks!
