Ok, i really like the learn' lesson i'm getting here since i'm about to do my first barrel swap. However i do need to say that plastigage has more than one use and isn't confined to just flat surfaces, i have used it for many automotive racing applications over the years. It's ability to form around whatever surface it was used to gage is one of the reasons it's still in use after so many years.

Now, ... may i sneak back out of this while i still have all my limbs. blue
