The importance of a torque plate
I've been well aware of the need to use a torque plate on a 440, that's why I have one. So being that it was 440 day again, I photo'd finished size with plate tight AND finished size with the plate loosened. The bore size, 2 inches from the deck, can, and has been in the past, been observed to change as much as 1.8 thou, just by loosening the plate. This one I'm showing moved about 1.4 thou.
