This is a great bit of info.

Ropes. Knots and rigging references

TreeCo · 30th January 2007, 05:33 PM

"On Rope" by Padgett and Smith is a great resource.

The Ashley Book of Knots shows over 4,000 knots.

'The Tree Climbers Companion' is a good book for climbers.

This link is to a place in Brisbane that makes double braid lowering rope but not 3/4. It's not as strong as the Samson stuff you get from Arborlink but about 1/2 price, however no 3/4.

Rope Online - Polyester Double Braid - White With A Colour Fleck Pair

Here's New Age Arbor's ropes, they're in Melbourne but they'll freight free for orders over $275 ... note the 3/4 double braid is $12.50 per metre.

Arbor Warehouse sells Samson 3/4 double braid, it's 9300kg ave break strength, prices only show per 200' but looks cheaper than the other mob.

And here's their pages on rope bags

The 3/4" Samson bull line that I have is really a beast. One hell of a rope.

Glad I looked in here - you did post the link to animated knots.

It was on your own site that I saw that first - right?

I had added it to my links to.

Now I don't need to start a thread.

TreeCo · 20th May 2007, 06:13 PM

Thanks for the link GW. Ken has a great site.

Sean Freeman · 20th May 2007, 08:12 PM

Yes very good to know.I heard somewhere that a bowline reduces line strength by 35 percent but i am curious just how strong my splices are.
Yes i splice braided and 3 strand.

Eric Frei · 10th July 2007, 09:31 PM

A splice is between 90% and 100%

Of course has to be done right.

All knots reduce rope strength, 35% sounds about right for bowline, worst is the square knot, 50%!

Best is the figure 8 and butterfly ... ironically also the easiest to tie, darned bullet proof that thing.

If you are using running bowlines to pull trees or spar over with trucks/machinery etc would be wise to have a clevis shackle in there so no rope on rope, also you can take 2 turns around the spar then the bowline ... it will take some heat off the knot.

jim1nz · 11th July 2007, 05:36 AM

Knots can reduce rope strength a lot more than you think, bowline - upto 40%

A good splice will be 95 to 100%.

Yea ekka is right, a half hitch before your final knot is about 85% efficent. (15% strength loss)

I generaly use a clove hitch with 2 half hitches but from time to time I do a clove hitch with a bowline finish.

Wait until Ipost pics.Seeing is believeing.

stirmantrees · 7th September 2009, 04:34 AM

so the bowline snapped at 60% interesting. should we then use this percentage as the bench mark for our rigging safety percentages?

Eric Frei · 7th September 2009, 08:21 AM

Yes, in rigging applications always discount the SWL by weaknesses in the system.

That's why I like splices and loops (knotless rigging), you retain 90% of the SWL.
