The thread on part one of the series found here (http://www.hammockforums.net/forum/showthread.php?t=31986).
The thread on part two of the series found here (http://www.hammockforums.net/forum/showthread.php?t=32036).
Part three of the series goes through the construction of two cord devices used in the suspension. Through each webbing loop in the corner of the hammock goes a small loop tied off in a Diamond knot. So here's another chance to see a Diamond knot tied. The GrizzBridge suspension triangle is a cord where each end has a soft shackle like loop that clips over the Diamond knot---so the video goes through tapering the cord, making the soft shackle loop, a locked Brummel, and burying the end. Instructions on adding a descender ring at the apex of the triangle.
After showing how to cut down a bit of aluminum tubing to create a shorter foot end spreader bar, and a TRUE CONFESSION on this particular design of suspension, there's a low res bit of footage on the RhinoBridge's maiden hang.
Still to come...the making of a bugnet.

Awesome.
Just curious, but is there a reason why you prefer the separate suspension triangle+descender ring vs. suspension triangle as part of a two legged spliced whoopie as you have made with a prior dynaglide suspension?
Thanks for the clear demonstrations.

Nice and clear, as always. Have you ever experimented with longer legs on the support triangle? You'd need trees a couple of feet farther apart, but it might let you use a lighter spreader bar.

Thanks. I won't say that I prefer one way over the other. Each has its own advantages....for the flat out lightest suspension possible, lose the descender ring. It is easier (but not as kewl) to find the midpoint of the cord as I did in this video and then lark's head on a fixed splice end of a cord that goes to the tree. The splice is stronger though. What using a ring does is to shorten the minimum distance possible between trees, because the splice bury is hard to make part of a tie-off. Indeed if you put a whoopie sling or a UCR above the splice now you have two buries between the triangle and the tree. Using a ring you can run a cord from the tree to the ring and tie it off using a slipped buntline or something similar....you don't have to have buries between the triangle and the tree.

Yes, back in the day I ran each side of the suspension triangle out to the sides of the tree! You're right you get less compression on the spreader bar...I didn't see how light the bar could be though. The other advantage to long sided triangles is that it raises the axis of rotation and makes the hammock more stable. I think I read once that TeeDee makes the sides of his suspension triangles whoopie slings so that he can adjust as he likes. I've got another method in mind to tinker with, if ever comes the day again when I have time to tinker!
thanks for watching...
Thanks for the explanation. I am thinking a Dutch Biner instead of the descender ring, just because I have a couple laying around looking for a use.
Are you using the same suspension triangle length (30") on both ends, or do you shorten it proportionally (0.83 x spreader bar length) on the narrower foot end?

Thanks for the explanation.

shorten it, I aim for roughly 80% of the length of the spreader bar, so on the short end of this hammock the side was cut to be 21".
Thank you again.
Now just need the new fabric and webbing to arrive...
What type of "whipping tool" is that that you use? I'd like to get one.
I can't find anything with a folding eyelet like I see in the video. Everything I search for has a loop through a tube.

I had the same question... If you listen the Grizz very very carefully he mentions it is called a Loop Turner. It looks so much easier than darning needles for burying line etc. He is a link to one I found on Amazon.

Spreader bar diameter specs per Grizz:
For 250 lbs and under use the 0.625 diameter bars
Heavier go up to the next diameter, 0.7xx
http://questoutfitters.com/tent_poles.htm
Spreader bar length:
Grizz specifies the bar length for the head end to be 36" (two 18" bars) and the foot end to be 26" (1 18" bar + 8" cut from another 18" bar... I noticed Quest is now carrying 26" length bars so they do not need to be cut, but it still has to fit in the pack... Just another option.)
Thanks Grizz for the great video series and extra help!:thumbup:
Thanks for this clear tutorial;)
Just on my way to repeat everything you've showed step by step. I only need some new material now. :laugh:

Just watch part3 for the umpteenth time & was confused about the Brummell knots at both ends of the suspen. Triangle. The first one I get, but how would you pass the long standing end thru on the second end with the other loop completed? Anyone have this problem? Thank you

I made a video about making a fixed length ridgeline with a fixed loop and locked brummel at both ends. I had some questions just like yours about how to finish the second brummel so I uploaded the clip of me doing it:

Glad to help!
Hey Grizz, Just curious, have you changed your formula for the suspension triangle? You where doing 80% of the spreader bar which is short compared to the Bridge hammock sold nowadays. I have made about 7 or 8 Grizz hammocks and now starting another. I have always had good results with you instructions but I did make my suspension triangle a little longer. BTW thanks for putting your time in doing these awesome instructions.

howdy--I continue to make _mine_ using something in the 75-85% range, more usually at the higher end. That works for me given (i) 0.625" diameter Easton poles, and (ii) my weight, in the 190-200 lb range, depending.
For a given suspension triangle and spreader bar length, the compression on the spreader increases linearly with
the weight of the occupant. So if I was selling one for a market where I might have folks in the 250 - 300 lb range in the hammock, I'd probably do what Brandon has done and increase the suspension triangle to knock back the compression for the larger end of the customer base.
hope this make sense.

howdy Shug! It would be better to see me hanging, but typing will have to do for now.
Hey, we're vacationing with the family of a son's significant other, and we got to showing
youtube vids with family members last night. Had to pull out 'Packa Pillowtalk', good fun!
They say you're charming, and that I'm crazy. Seems backwards to me.... <grin>
catch you on the rebound
