Er--- uh.... Graphite is non hygroscopic.... actually its a fabulous water repellent. That said... I like teflon better too... but because is it globular in structure and not crystalline. Seems to work better as a lubricant for felt bushings in anycase. Cheers RicB I prefer to use microfine powdered teflon. Graphite seems to attract moisture in humid climates and gum up. Maybe there are other chemical things coming from the wood, but it just doesn't seem to work well long-term. Andrew Anderson
