Cheap Cheap whoopee
Hi, new here but been at the other forum for a while.....
Anyway, I am enthralled by whoopee slings and possibilities,
But because I'm cheap, I want to make them from locally available 3/8 inch yellow hollow braid poly rope.
On the package it says working load is 200 lbs or so.
But the specs on line gives 2880 lbs as tensile strength.
I'm a big guy and with a 30° hang with my weight 200 lbs of tension is possible.
Am I in danger of catastrophic headfirst midnight dismount (CMHD)?
that might work but i wouldnt trust it.
Amsteel is SOO cheap and easy to work with. On top of that once you get it down youll have some sweet kit. just my thoughts on the whole thing.
Its OK to be cheap. But your suspension really isn't the place to do it. Amsteel is pretty cheap. Get a hold of Paul at Arrowhead, he's also in Idaho. I'll bet you'd get your order the next day:thumbup1:
...I believe in doing stuff like suspension only once,.....pay a few extra pennies and you wont have to worry about a hassle down the road........just my two cents :)
The big reason amsteel rope is so popular is the strength to bulk ratio. It packs small and light.
Your choice of 3/8 poly hollow core will work. I've used it in the past, down to 5/16ths diameter. Held me up just fine. Makes fine whoopies.
As stated, there are better choices and your money can be more wisely spent. You'll probably end up modifying and upgrading eventually, we all do. Might want to just get the good stuff from the start.
That's than 800 lbs. more strength than the webbing mountain climbers have been depending on for many years.
It's also a better than 14 to 1 safety margin, 10 to 1 is a lot, and 5 to 1 is quite acceptable for applications where there will be no shock loads.
One thing though, while you'll retain 80% or better strength with a splice, as opposed to a knot, you should also consider the radius of what ever your attaching to. Smaller radius' = more stress.
You won't be jumping up and down in your bed will you?
This is from OSHA,
Climbing ropes shall be used by employees working aloft in trees. These ropes shall have a minimum diameter of 0.5 inch (1.2 cm) with a minimum breaking strength of 2300 pounds (10.2 kN). Synthetic rope shall have elasticity of not more than 7 percent.
You've got to be careful what you listen to around here. I suspect a lot of these guys work for some of these manufactures.
Many of them will have you spending 10 times what you need to.
Having said all that, poly-rope isn't very nice to work with in my humble opinion. I like softer more pliable material. But that is a matter of preference not function.
Really Jeff P./Weerdeater.

I don't think you have a grasp on the whole purpose of this forum.
I do not, nor have I accepted or earned any earnings from any of the companies.
I, personally, am offended by your recent comments.
They are derogatory and totally lack any bias.
For future reference, please use only factual info, you are speculating that the info here is just to the financial benefit of a few.
I completely disagree.
This forum is free to join and free to leave. If you believe the info passed along on this forum is just for the all might dollar, your totally wrong.
The purpose of this forum is to advance the comfort and hanging experience.
If I find a product that works and can help others and in some way suggest it to others, it is not because I am making money.
Your being quite irrational in your comments.
I am a member here first. And recently, due to some creativity and craftmanship, became a vendor. I pride myself on my relationship with HF. Not only have I learned a lot of useful information, I have made a lot of friends. And had a few good laughs.
If you get your jollies by saying things like this, please don't comment any more. If this is your way of trying to make friends, it ain't working.
If you have good practical advice to give and share, then by all means join in.
To sit there and point fingers at my friends and family here on the forum, will not be tolerated.
Man, you have been eating too much weed! Put it down!

I reckon you might have insulted quite a few of us who have read your post. :(
Weedeater, I'll respectfully direct you to this thread. I'd suggest that you read and understand it thoroughly before further posting. You're beginning to insult and offend some here. Folks here know who are and aren't gear manufacturers and no one gets kickbacks from giving advice, especially when said advice bears in on someone's safety. As far as the "the three dollar stove" is concerned, jealousy really is an ugly emotion. :rolleyes:
Back on Polecat's original topic...
Polypropylene is known for "walking" which means that it can stretch without recovering. It will actually get longer, and then break. So, if you use polypropylene, make certain you are well under the maximum working load. 200 lbs maximum working load is not enough.
Amsteel stretches less than any other rope, even less than wire rope. It is perfect for hammock suspensions.
