Can anyone recommend some first grade pulleys? I am looking for
something bigger than what they have at hardware stores, 3 or 4

I have two sources. The best are from B&B Small Engine, a vendor here in
Santa Cruz that caters to tree climbers. They're pretty expensive -- I
think I last paid about $50 each. I just did some searching and found
this listing, which appears to be the same pulley at half the cost. The
ones I have look like the RP-115.

Here's a page that shows that the sideplates rotate around the axle, so
that the rope can be inserted in the middle, not only from an end.

This appears to be the mfr. http://www.cmi-gear.com/
My other source is West Marine. It's important to match the pulley
sheave to the rope.
