What's up with that ?
Maybe a double dog dare would get ya motivated.
Ha! Nobody brushes off a triple dog dare. That would have been the final straw!
But seriously, clean holes are still holes. I’ve been clear that it’s not dust or dirt. “Dust and dirt” does not add to the conversation and it’s rude to keep prodding after that’s been clarified.
Maybe I need to paint a better picture:
You bore a hole through the center of a metal rod. The walls of the bored hole looks mostly normal except a portion has a blossoming of pits. Those pits appear to be from bubbles that were in the metal. A few would be ok but this is a “blossoming” of what appears to be thousands of bubbles that were cut in half and exposed in the walls of just a few inches. How many “bubbles”/voids were not exposed? Is that section of the metal rod practically porous? Is this something you expose to 60,000 psi?
