    Alternative indoor hang

    Ok, so unfortunately I don't have 2 trees at appropriate distances in the yard. I live in Florida, so no basement with rafters. And from all the info on the forums (and a few hand calculations), the stress on the rafters is a bit questionable.
    So what to do?

    This is what I came up with. An 8 foot 2x4 (which I just happened to have in the garage) as a stiff ridgeline to take the compressive stress. This way the only stress on the eye bolts in the beam is a downward force of my weight. (ok, a little outward force because the eye bolts are not directly above my attachment points)
    I'm going to clean up the suspension a little, and maybe a longer 2x4 to allow for a more natural hang. But all in all, a good test bed for my DIY hammocks.

    Any thoughts?

    Cool Concept! Only concern I'd have is, depending on the quality of 2x4, whether drilling a hole that close to the end of the 2x4 that you're hanging from would cause the board to split (maybe over time as the board dries). Looks like you may have the strapping wrapped in a certain way to account for this but it's hard to tell for sure. Positioning over the pool would ensure a softer landing.

    Thank you , thank you, thank you! I finally understand what's meant by a "structural ridgeline".

    I like the idea.
    Not a fan of the big drilled hole, though. Wrapping your support straps around the 2x4, then securing with a knot, may work better.
    Whats holding everything, up above..? That's got to be really strong and secured well.

    Yep...lose the hole, and let the straps wrap around the 2x4 just outboard of the eyebolt.

    Love the concept, but....doesn't that sucker spin?

    About the hang

    Thanks for the feedback. I know the holes aren't the optimal attachment method, but I wanted to fix the distance for the "ridgeline". The second set of holes for hanging it to the beam was a bit of a lazy moment.
    I will probably swap the straps for a couple of chains and put through bolts in.

    The setup doesn't spin. It is surprising stable. Only downside is that I need to enter the hammock from a more "side" entry. The ridgeline is not in the way once your in, just on entry. And I guess if I were it sit up too fast...OOuucch

    If the spreader is too close to the hammock you can use a longer spreader and use more of the hammock suspension line, and maintain the same hammock sag. If you do that, you get roughly 1/4 of a foot of separation for every foot of added spreader length.

    About those forces... you are splitting your weight in half because you are using two attachment points and the downward force on each beam is equal to that. But something else is going on at the eye bolts, the holes they screwed in to and the hammock suspension. In your application it isn't much to be concerned with because you are not departing too far from vertical. But as the 'drop angle' starts departing from true vertical you start generating extra. Where I would start worrying about it is when that angle starts getting large, especially if someone starts trying it with a single attachment point.
