I am just curious why you cant buy 3 stand eye slings for rigging anywhere. Is there an issue with a weak splice or the low strength of 3 strand? I saw some 3/4" TreeMaster on clearance at Wesspur and was thinking this might make a decent eye sling. Thoughts?
 
They can be made to order for specifications needed . We have had some made with two 6ft and one 10ft slings for rigging when the rigger is in the tree , but when in the bucket he uses a variaty of straps to rig for several diferent reasons . also 9/16 rope or larger, can be used (eyed on one end )in a tri-pod cofiguration and tied with a Bolin or timber hitch ... 2-6ft X 1-10ft , 2-10ft X 1-16FT ect... I don't use this system but other people do and i'm told it works well for them . I will send a pic of how we rig in tri-pod fassion with this post. w.k.b. tulsa
 
Sorry again... keep sending you crap , New to computers. Having trouble un thumb nailing when choosing pic , guessing continues

You know I was thinking about this the other day...because of the ease of splicing i mean jeez i spliced three stand while I was a cub scout...I mean the new adjustable friction saver is made with three strand...hey if it meets the strengths why not? I am interested to see what comes up
 
3 strand rope lends itself well to a wide variety of rigging slings and adjustable friction savers. Items of which can be custom constructed in a matter of minutes in the field.

Why there isn't more available to the consumer leaves me wondering too. Certainly strong, cheap and easy enough to manufacture.

I'm sure it's all marketing within the industry.
 
In TODAY'S world, IF you can do or build it yourself, the mindset is "It must NOT be very good".

Sorry to sound cynical but the ART of doing (or making) things yourself is taited by regulation and safety factors. Sure, no one wants to hurt or get hurt by sub-standard gear, but trusting manufacturers and retailers isn't the be-all-end-all either. REMEMBER the broken ring thread?
 
Polyester three-strand can't be beat for ease of splicing in the field and making up rigging as you go.

Along with the basic knots splicing three-strand rope was a requirement that each new climber had to learn and demonstrate within their second week on the crew.

I taught so many young men how to splice three-strand that I was able to do it blind folded. Back, eye, or straight.

3 strand is OK for an eye sling. Keep in mind it is extemely stretchy, but durable. There are better rope constructions to make eye slings. I think that's why they're not popular.
As long as it's spliced per manufacturer's recommendations, go for it. Five (5) tucks minimum for synthetic fibers.
I have two 3 strand spliced eye slings in my arsenal. Both 5/8" diameter. The rest are mostly DB and a few hollow braid.
 
Alright, it seems that 3 stand will work but there are better choices.... which I kind of figured. I am surprised at how many people use 3 strand. I always thought it was cave man stuff but I have become a fan after splicing an adjustable friction saver out of it.

As for the stretch, could that be a good thing to take some of the force while rigging? I know that sometimes stretch is bad like if you are rigging out a branch that is close to roof. But if you have room to work with, wouldn't it be a good thing to have a sling that has a little bit of stretch?
 
next time you get your hands on specs for ropes look at the swl for 3 strand compared to double braid, tenex, etc. 3 strand is USUALLY a bit lower. That's why the started making ropes that way. Also I've been taught that your rigging line should be your weakest link for safety wise. so your blocks and slings should be stronger than your line and if youo use 3 strand the sling would be a weak link. That is the best answer or argument I could come up with for your question. That said I say go cray with 3 strand I like eye slings but what ever you had in mind continuous loops are handy to. That said I also use double braid, tenex,etc. Just look at each job and know your equipments limits use the right tool for the right job. Know your limit and play within it.

Take a look at some tie-up lines on tugs / Three strand is plenty strong if one uses the right size. Theres some tough three strand out thier today/ might have to check with a marine outfit. I enjoy workin' with it myself.
