I hand polish too. All those controls should definitely be having a noticeable effect.

Buzz control might not be working because the alignment is throw off by the damaged slug. I suppose the slug could be replaced but finding one with the correct characteristics could be tough.

The centering controls are actually magnets. Unless they lost their magnetism, they should be moving the image around when you rotate them.
