Yes, great all around. But I have a question. Those flat belts, if
they are of considerable length, are folded into "figure 8". I wonder
why, to avoid thel flopping around?
Do you mean why are they given a twist so that
they are shaped like a Mobius strip.
The reason is it makes the belt last longer because the belt
contacts the pulleys on both sides.
