    Thanks, I meant the rule that flippers have to be tethered to the robot by a chain, and what to do with a 360 lifter. I'm guessing that doesn't apply to it. Thanks anyways.

    I'm sure there's a reverse-thread screw extractor for that size. You'd end up ruining your screw though. Hopefully you manage without.
