This is a question I have not seen addressed , in a flipper is any lubrication used in the bushings or pivot area ?

Fred, a drop of fine oil on any liner locking type can be good, but I wouldn't count on it correcting a problem because of bad blade alignment.

The problem with oil and a liner or frame lock is that people use to much and it migrates onto the locking surface of the blade and lock bar face. This can and will cause the lock bar to stick on many knives. Personally I just put a dab of oil on my finger tip, spread it out thin then apply it to the bearings or washer. It is hardly enough oil to make the part shine but enough to give it lubrication. If your using phosphor bronze washers they are self lubricating anyway.
The flippers I make have to work flawlessly dry with no oil, if they don't something else is amiss. The extremely small amount of oil I do use during assembly is for reduced wear of the parts over.
