I was looking up some knots and I think I discovered the problem and how to fix it. The Lark's Head comes around the outside edge of the ring causing the second ring to come off-center.
The Prusik Knot could have the same problem. But probably not as much.
However, using an Anchor Hitch relieves this problem.
And here is how to tie it.
I do like the buckle and strap system much better than the Tree Huggers. I've been following the ring and carabiner idea for a while and really like the simplicity. I think the carabiners will put less stress and wear on the webbing than the webbing puts on itself. So this morning I decided to go for it. I priced 4 rings and nano carabiners at the link provide earlier vs. REI. REI was actually was cheaper because the rings were 10 cents less each. The carabiners were the same price unless you order 6 or more from the other provider. REI shipping was $1 more but I figured I would get some of it back in dividends later to make up for it. As I ordered I found I had enough dividends already to cover my order, add a pair of socks and only have to pay 75 cents. How cool is that?:D :D
The moral of this story is that if you shop REI (at the store) with a bunch of your friends, and they're not members, get them to put their purchases on your member ID. Thanks guys!:)
Cool the closet REI to me is about a 5 hour drive to MI.
One things that I saw on my 1 night with the rings is that I put a lot of stress on the bark. They were thick soft bark trees though. They were the only ones around. I think this was because I put 1 loop around the tree vs 3 or 4 with the speer knot.
I put the strap through a look I sewn in it. I am trying to decide if I want to do the biner thing or not.
There's no reason you can't wrap the strap around the tree 3 or 4 times and then through the loop (or clip the biner to the strap). That should reduce stress as much as the Speer 4 Wrap Knot.
lvleph, wow, that anchor hitch really does keep things even. I hope to test it out fully when I get my Syderline in.
Yeah, I like this support system much better than the Speer knot, especially with the descending rings. It gives you much more adjustment.
I bought the rings from http://www.apsltd.com/Tree/d3000/e814.asp
I got the 1.5 ID, but it seems a little wider than 1.5 inches. So I'd order the 1.25 if ordered again.
The anchor hitch works well, but be sure to an overhand knot or two on the end to use as a stop.
Overall this ring/buckle support system provides much easier adjustment than anything I've seen on any of th big three camping hammock makers. With the Speer System I had to get out and retie that wrap knot. But now I just tug the webbing a bit and it works. Loosening isn't much harder. Throw in a structural ridge, and I've got something going here.
Thanks to Ed Speer for starting this DIY hammock movement.
