Not only is plain old nasty castor still the most reliable lube for your two cycle kart mill, it also works terrifically as a drill and tap lubricant. Bob Kurkowski told me this several years ago, and I alwaysl keep a little squeeze bottle of Blendzall near the drill press. When ordinary drill lubes run away from the heat of the drill bit, castor seems to run TOWARD the heat! Spray carb or brake cleaners clean the stuff away very well. Ted
