Amy,
Just a word of caution, I saw a cardiologist once, and he told me I was too sick to go home. When I finally got home again, it was 8 weeks later, and it took me a year to recover. Were this me, I would align the sheaves now, before the appointment.
Harry,
I'd love to teach rigging. I think I am pretty good at it. I do correct people's thinking at every chance that I get. It is usually a sheave that they all call a pulley. I am still thinking about that alternator/serpentine belt question.
