Okay- a little bit of bad news. The directions I have for it are in a Brion Toss book. I don't like to post info from books since it's somebody's work.
I've sent an email to Toss to see if he minds if I post it.
In the mean time, there is another option. Send me the rope and I'll splice it. Since this is, in many ways, a "treehouse" project, I'll splice it for free (you have to pay shipping, though).
I'll let you know when I hear back from brion.
love
