What sort of lubrication do you recommend on grand knuckles? I have installed new knuckles and am not sure whether to use a graphite mixture as Reblitz says or whether teflon powder may be better. The jack tops on this Bechstein appear to have a kind of shiny plasticised coating. I would much appreciate your suggestions.
