Padded Loading Pin (from a pipe & rotor) for weights

Weight lifting loading pin from black pipe and a used rotor. No welding. For use with a pulldown exercise machine.
This was one of those projects where you think at first, 'oh, that'll be easy,' but then you start to really consider everything that's going on with the physics. Unless you're willing to be constantly annoyed by something that's 'simple to make' (x150 reps per week), there will be some design problems to iron out. Most loading pins are either tricky to load or expensive, and nearly all of them are noisy and destructive to a floor. Few are designed with a DIY home gym in mind. The finished project here is strong, easy to load, and silent.
