I hope they post it.
Seriously, and for the record every single block is pressure tested. How your block escaped QC is still under investigation. Our organization is composed of people. People sometimes make mistakes. We learn from them, and try not to repeat them. |
My experience with acetal/delrin is it's good at absorbing impact (at certain angles). It doesn't responded as well as stress loading. That would be a better way to test the block. Lay it on angle so it's resting at the top on the outside edge of the top and edge of the inlet/outlets edge and press down on it. I thick the stress (weight) at that angle might form a crack over time. It will take the whack with hammer very well. Used in paintball for years now.
