Porty Questions

[MasterBlaster]

Hey Butch, I like your port-a-wrap attachment pics. I have three questions for you if you have the time:

(1) Do you always use this type attachment, or do you modify for really heavy pieces?

(2) Could you post some pics of your porty (unless it's patented)? I like the way it looks, and would like to build one.

(3) What type rope is that (brand, size, tensile strength)? It favors 3/4" Arborplex methinks??

1) No, it'll take as much as I'll ever wanna give it.
2) Sure, I just copied the style of the original - no biggie. Modify it as you see fit.
3) The rope? It doesn't matter as long as it's the same size as your rigging rope.


This is the old style


I like this style better.

Not to be a smartass, but your rigging rope should always be the weak link in the set-up.

 

[MasterBlaster]

I'll buy that.

 

[Frans]

I thought the tree was the weak link?

 

[Old Monkey]

I thought the tree was the weak link?

I said that during a climbing class and the instructor shut me down. I still think its the right answer.

 

[MasterBlaster]

They're ALL the right answer.

Haha, Darin, your not supposed to break your rigging point out!

 

[Old Monkey]

If you tie off your line to a nearby tree stump, put the other end on the GRCS and crank until something fails, which would you expect to fail in most cases, the block, the GRCS, the rope or the rigging spar? I know if you are rigging off the trunk of some big tree its not going to fail but if you have some nice high spar to rig your brush off of, its going to be the spar.

I think the whole "weak link law" as Don Blair describes it says the rope is supposed to be the weakest link so that in case something breaks neither the block nor the porty will be released, which might kill the climber. In reality this is impossible to achieve since the breaking strength of the tree is unknown. It is still something to consider when building a rigging system though. At the very least it helps to be aware of the strength of each component in the system.

 

[Burnham]

I'm with Sean on this one.

 

[Bounce]

I'm with myself as well.

 

[MasterBlaster]

And I'm at one with myself.

 

[rumination]

Me two, I'm at one with myselves.

 

[Burnham]

Y'all are nutz.

 

[Newfie]

Me two, I'm at one with myselves.

Do myselves live near myshobbits and mysorcs?

 

[Koa Man]

When in doubt, cut it smaller.

 

[Fiddler]

When in doubt, cut it smaller.
