Brady, I am a miser at times. I planned to make some eccentrics on the lathe. Chuck the stock up off center a tad, drill a hole, then re-chuck and turn to size. I planned to make the washer part of them large enough to put a couple flat spots on them so I can adjust them & Hold them while tightening the nut. Might work might not, but I'm always up for an adventure.
