And the result: The flake held and the test block was left swinging in mid air. However, I was so amazed that the flake held that I went up and checked it out with a crowbar. It easily came out when levered out on. Of course, that begs the question: How many whippers would it have held before failing? Or, if someone pulled out on it, would it have failed? Either way, I removed the flake because after seeing how loose it wasy I didn't feel right in leaving it there. Then, I added a new bolt.
