Apparently, signature that I used from 2006 no longer tolerated so now deleted.
I started a thread on Brion's method here. Brion has the description and illustrations in the book I referenced. He calls the method the McDonald Brummel, named after his illustrator.
I contacted Brion Toss by email about scanning and posting his description and illustrations, but he was in FL at the time and his front office guy forwarded the email to his lawyer and said I would have to wait on Brion's return.
OldGringo found on on-line pictorial of the method and I posted a link in this post.
Then silentorpheous found a video and posted the link in this post.
The illustrations that Brion uses are easier for me to really see what is happening, but the pictures and video are pretty good also.
I think I got some reply from Brion but my email provider had put it in the spam folder and I had erased the contents after scanning the titles very fast and only afterward remembered seeing something. But by that time we had the two links above and I didn't pursue the matter.
I find the McDonald Brummel to be fairly simple to do. In some respects it is simpler than the Sansom Ropes method if you have a really long rope. If you are putting a locked brummel on both ends of the rope, then Brion's McDonald Brummel is easier for me. TeeDee uses locked brummels on both ends of the cord used in the arc on our Bridge Hammocks and since the second locked brummel must be done using only one end of the rope, Brion's McDonald Brummel is the only game in town.
