Re: [Hammock Camping] Hammock support/ webbing strength?
- For a trouble free answer just buy the webbing from Ed. I bought some
to make longer tree huggers for my H.H. He sells it buy the foot.

Howdy-- I have a related (sorta) question. I have a HH but have
recently bought Ed Speer's book to play around with making some
hammocks...(mostly so I can go with my kid, so I have taken
inspiration from Jeff's site with what he has done for his boys).
Anyway, in Ed's book he recommends 1" polypropylene webbing tested to
like 600 pounds. OK fine, but when I checked on OWF, Quest, etc, they
don't list the breaking strength of the webbing, only the width and
whether it is a loose vs tight weave, etc. How does one know the
difference in break strength to order the right stuff? I don't want to
buy the low break stuff and have a hammock disaster. Any wisdom?

Yep - he rarely plugs his own stuff, so here's his site:
Scroll all the way down - it's about the 5th product from the bottom.

backpacking, and he's outgrown the kids hammock. Time to make him a
full-sized one, I guess.
If anyone needs the kids one, it's probably good for kids up to 3.5'
tall or so. You pay shipping and it's yours. Hammock body and
whipping only...I'm gonna recycle the supports.

I did some research a while ago on webbing strength. I have misplaced
it, of course, but I think I remember the main conclusions. Breaking
strengths vary so the weave does matter, but only if the webbing is
less than 1". Webbing is strong, so any webbing that's wide enough to
protect the trees will be strong enough. Nylon is strongest (except
for spectra, dyneema, kevlar and the like) but it stretches,
especially when wet. Polyester is almost as strong as nylon and
doesn't stretch much. Seat belt straps are 2" polyester and have a
breaking strength of something like 10,000 lb or so. I don't know of a
good source for seat belt strap material, though. Polypropylene is the
cheapest and the weakest but even it is strong enough if it's 1" or
more. Some polypro strapping is a bit marginal on strength, though.
It's strong enough but doesn't give as big a safety margin as nylon or
Basically, any 2" strap is overkill on strength and very easy on the
trees. Any 1" strap is strong enough. Narrower strapping should be
nylon or polyester.
> spectra/dyneema webbing for 80 cents/foot...That's a bit of overkill. Any webbing that's wide enough to work as a
tree-hugger is strong enough. No need to pay extra. Although, it
wouldn't stretch would it? Hmmm...
