Great post Dick, and thanks for the drawing. Helped me to see how they are done and gives many of us a better understanding of the process. Daryl, although I like finding original cans with the contents intact, I too place little value on full ones.

I have a half dozen or so full ones and 2 of them are leakers that seep fluid now and then. They're now down on the bottom shelves in case they ever let go. I guess the trick in the great white north is not to heat the garage in the winter so the oil thickens and they stop leaking. lol
