Bad Mechanics Files or How Not To

[rickpaulos]

I had a thread going on the sbf (before it got hacked) on some really bad bike repairs.

A new find. It almost worked. The guy said the pedal kept locking up as the outer nut would turn in while pedaling. A lock nut might have solved that problem. Cool is the guy used 2 hub cones pointed into the stripped out crank so the hub axle was centered. Well 3/8" hub axles aren't as thick as 9/16" pedal axles so pedaling hard would just bend it. No bearings. Most pedals don't have them anyhow. So many cheap box mart bike pedals are just plastic directly on the pedal shafts.

Sometimes I just stop and wonder, sure I can do this. But... why? Then I look at this piece
of mechanical artwork and think out loud, "Yes! THIS is why! DO IT! Conscience be darned!
Because I CAN, THAT'S WHY!!!" Some kid somewhere is saying, "Thanks Dad. You're the best."
and scratching round circles into the paint of parked cars with that threaded rod sticking out.

On a bottom feeder Pacific. Bridge ripped apart. Why? Who knows. Trying to fit a larger wheel? The bridge serves a purpose. Keeps both legs moving up an down in sync to keep the wheel straight up. Holds the brakes in place. This one would allow the brakes to turn away from or in to the wheel. Would the wheel axle alone do all that?
