Shame, shame , shame!
If you don't show that thing the love and attention it deserves it
will repay you with travel play and tapered cuts you
will have nightmares about.
Seriously though, surface rust is my biggest problem being near the
coast and having no roof insulation. If there is a dewy night all the
metal on the lathe goes straight to dew point first and beads up
in a fine mist of moisture. Lots of regular oiling needed.
Look after that thing boyo!
