View Full Version : Amsteel diameter
What diameter amsteel would you recommend for use on a DIY hammock. Looking for approx 250# capacity. What other factors "trig equations" need to be considered???

A general rule of thumb is a 5 to 1 safety ratio. Your weight x 5 = 1250 lbs. Therefore, 7/64 Amsteel is sufficient. If you are really paranoid, get the 1/8" Amsteel, though I think it's overkill.
Thank you! It's been a long winter and trying a few ideas. Thanks for your help!!!!

I forgot to mention why 7/64" is sufficient - 1600 lbs. breaking strength.

7/64 has held me and my daughter swinging pretty good several times... We are about 240 together...

Yep, 7/64" will work just fine.

I made my first set of DIY Whoopie Slings with 5/16, because that's all the West Marine by me had.
They are too bulky, but not really that much heavier than my 7/64 set. I put them on a spare DIY hammock I use for my kids. And hey I can always use them to tow a car with the 13,700lb breaking weight. :)

Wow! No worries about those breaking :) Congrats on your first DIY set.

No doubt, but now I am an old hat at them, super fun, learning lots.
I have made 4 sets now, for other project Hammocks, also going to make an adjustable RL soon. Which when successful will probably mean a few more made.
I can make a set now in about 5 minutes complete with Locked Bromels and Burried ends, sans the stichting.
Once I stared at this PDF for a few it was super helpful.

so is it safe to use 7/64 for a rope swing?
should I go even more then 1/8.
stuff isn't heavy and would love to show off a double backflip.
but want to make sure it's safe
it's never too early to think about spring/summer.
The 7/64ths is plenty good for whoopie slings. However, if you are doing a rope swing, I would opt for the 1/8 inch amsteel. Depending on how crazy a person gets, there can be a lot of force on a rope swing. I believe the 1/8 inch amsteel has a breaking strength of about 2500 pounds.

I'd step up to at least 1/8" for your rope swing as the dynamic forces might be higher than what we see with hammock loads.
