In another post I had a couple of stiff tuners. They were new and shouldnt be so stiff. Some of them broke in after a blast from pegwinder on a drill but one of the others I pretty much drove all the old lube out and packed it with new stuff. So... I always used to use lithium grease. It works but sometimes the results are less than spectacular. Erlewine suggest vaseline cut with a bit of naptha so it penetrates (tried it this time and dont see it is that much better than lithium. The last time I tried to `save` some vintage klusons neither were of much help) What do you prefer to grease vintage kluson style tuners?
