I apologize for my earlier question.....its just that I consider it a waste of time and money to calibrate rulers and your average tape measure.....I know it's done.
The precision steel rulers are a different breed though.....and there are some situations where those DO require calibration.
Just my thoughts.....but then, maybe I am a different and strange breed.....
