    Back Arch

    All-

    I was hanging this last weekend in my BMBH and had a new experience. I woke up and my back actually hurt. When laying in my hammock it felt like my lower back had a slight arch to it. Similar to using a weight bench to do a chest press and arching your lower back.

    Has anyone ever experienced this? I was wondering if I set something up incorrectly. The only thing I did different this time was hang my pack from the suspension triangle at my feet. When I've hung it from the hammock in the past I've hung it from the head.

    Thanks for your insights.

    Sincerely,
    Dave

    I just bought the JRBBH (my 3rd hammock) and have used it on 2 hikes, set it up in the back yard etc. I love the flat lay and sleep better in this than my other hammocks.

    I noticed that if I set it up too tight that I had the arched back that you noticed. When I stick to the 30 degree rule by setting the suspension straps at a 30 degree angle it lies perfectly. So try to loosen your suspension a bit, maybe slide it higher on the tree and see if this helps.

    Hey Cookie,

    Your signature quote isn't an "Unkown Author", it's Hunter S. Thompson.

    I too have had the back crink before. I think it was because I was strung too tight in my WBBB.

    inverted banana - too tight

    I started off using the JRB guideline - tighten until the bug net is taut and then relaxing an inch or two.

    Finally I took the time to adjust and test until I found the tension/distance I liked.

    I attached a piece of string to the upper rings at both ends as a guide for a few trips.

    Now I can "kind of just look at it and know".
    Love my JRB BMB

    All-

    Thanks for the info. That really helps!

    I guess I was so concerned about not having my underquilt touch the ground that I overtightened it.

    If that's the case, then you need to string your tree huggers up higher.

    The only two trees close enough in my yard are on a hill...so when I string my hammock up I have to put the head end as high as I can reach, and the foot end (which is slightly down hill) I have to throw the 'biner over and around at about 10'-11' feet in order to get the correct hang-angle and not drag quilt.

    Hey LR thanks for the info. My Wife has this quote on our frige but she cut off the author's name. Always wondered who it was.

    This is my present procedure:

    Attach, center, tension, height.

    • Attached at both trees with webbing run through only one side of tri-glides.
    • Insert spreader bars
    • Adjust, as needed, to center.
    • Adjust tension (width between rings) & run webbing through other side of tri-glides
    • Sit in bridge and, if required, move the webbing loops higher on trees.


    I also set the head end slightly higher than the foot end.

    .
    Love my JRB BMB

    Have you thought to employ a SRL to allow for rapid ideal curve reproduction?

    +1... Same as the standard directions... Whole drill can be done in under a minute with experiance.

    If properly hung.... sit in it, adjust height so thighs are parallel to the ground, ie chair hight hang and uq will not touch ground.
