You lay a dam nice bead, we sure could have used you were I worked.
Northrop Grumman always supplied the flgs for their jobs, predrilled with a serrated face, it sucked, one application called for the bolt pattern to be 5° off center, that job sucked. Your making these parts with no knowledge of what attaches to them or how critical location has to be. I definitely enjoyed my first long term job were we made our own product, making other peoples stuff can be a real challenge, not knowing the whole picture. I hated Nuclear or Military work, stuff is so over engineered. But probably for good reason.
