I have spent a great deal of time on die building and stamping jobs, dealing with everything from soup to nuts. What I find most frustrating are die shops and stampers that waste a great deal of money trying to correct oil canning problems rather than trying to prevent them so they don't have to be corrected later. Recently I was in a die shop that was driven by its customer to correct an oil canning problem by reshaping the metal. After days of refitting and respotting the dies at its own expense, the shop proved to the customer that the problem could not be corrected by trying to coin, beat, or reshape the metal, but it could be prevented. Preventing the oil canning would require a larger blank so that the part could be stretch-formed.
