Ah you see the light. A bolt with oil behind it can leak if it isn't tight. You know threads are like ramps and anything can slide down a ramp if jostled enough. The aircraft industry has recognized this since about the Wright brothers time. The torque is the primary method for holding the parts together but a secondary method is the wire or a cotter pin. The parts can't move.
IMO drilling holes in watermelons is a God given right. I think it's even in the Constitution. I mean what do those punks who write all those rules about safety know anyway? This too can apply to cantaloupes and muskmelons.
Yes I can. After passing safety, head toward the starting line. If you see a bike coming from the opposite direction you will know instantly you are pointed in the wrong direction.
