No, not that perverse....although my wife might disagree. Anyway, the way it's built is a bit hard to visualize I'm sure. I have a 1/2" bearing press fit on both sides of the chassis wall using a fender washer between the rim of the bearing and the wood to ensure the small rims of the bearings don't pull through the wood chassis. Through those bearings I have a carriage bolt with the head of the bolt on the outside of the chassis. The square part of the head interfaces with the swing arm. I have a square cut washer as a spacer between the head of the carriage bolt and the swing arm (because the swing arm is too thin). The swing arms rests on the bearing. On the inside, there is a shaft collar (round type with a single set screw) mounted on the carriage bolt. The whole assembly is held on with a 1/2" lock nut. I tightened the nut before replacing the set screw on the collar with a grade 8 bolt being used as a lever. That lever is tightened down to the point where it indents itself into the carriage bolt and doesn't move. So, if you looked at like a sandwich it would go: carriage bolt, spacer, swing arm, bearing, fender washer, chassis wall, fender washer, bearing, shaft collar, and nut. I don't know if I have any good pics of the set-up on the site or even at home. Since the shaft collar is attached to the suspension springs, the carriage bolt and swing arm have to stay indexed to each other using the square part of the head and square hole in the swing arm. There is also a square hole cut on the wheel axle side of the swing arm. The axle has another washer as a spacer and the carriage bolt is held tight to the swing arm with another 1/2" nut. It's all very solid.
