Possibly. I've decided the best way to test this is to get a fish scale that I can slide under the strap, then test how much effort it takes to lift the strap from the tree when under load with a...

Last night I slept up at campsite 30 in the Smokies. I did the multi-wrap thing with my 1" straps (as usual) and when I got home my mule tape order was here, so I made a set of straps to experiment...

Gredemeer, you were using mule tape weren't you?

I've seen this and I think that it's a product of two things: the friction of the tree will put more of the load there because it isn't a perfect world and the load isn't getting transferred the same...

I know there is something to this. I'm just not sure how to calculate that in.
But for arguments sake lets say that the friction is also a product of the surface area of the strap. Less width would...

I'm no rigger so I can only guess why. But I would think that the reason for that is they are not concerned with hoop stress (this is what I have learned is the technical term for what we are...

Pictures of the test in case anyone was interested.

I've done a couple of initial tests using Mustardman's idea within the limits of the equipment I have. I really don't think this is proof that it works, but it does point out that this may be...

Research on winch design trying to figure out how to calculate this came up with this nuggets:



So larger trees are like larger drums - less force per area, and the same thing with wider...

I think I get what you are trying to say. Basically you should always use a 1" strap because it is better. If you want more wraps get a longer 1" strap.

But a few months ago at the UL hang there...

Well I'm not sure. If the first wrap was done under load it would be true, but if the first wrap or two is fairly loose, then the top one starts getting the load and would have to somehow work that...

I sort of agree with this. Although I do think 1" is probably pretty optimal even if it wasn't the most handy stuff around. 7lbs per square inch isn't a lot of pressure.

And I do see the point of...

It depends on the diameter of the tree really. The bigger the tree, the less it affects it. Once I started thinking about this it made sense based on my observations. I'll answer the question using a...

Howdy all. I haven't been posting much because I have been working a ton of hours lately. It's nice to still have a job considering...

Anyhow, while I was working about 90 hours last week a spark...
