Gentlemen, Go to "links" look up Rebop. There's a picture Jim took a couple of years ago at EXPO of a pulley. the bad part is that because of the low volume tooling, and the amount of machining and balancing required, both of which are very time consuming, they cost $325 plus shipping. Yeah, I know that;s too much. But it is what it is and the next batch will be more expensive, aluminum has doubled in cost since January.
