found this link while looking for some instructions on splicing braided rope. thought i'd share it. www.machovec.com/rope/splicing/splicing.htm |

but splice and a back splice are the same thing IIRC. Also known as a donkey dick Nice post. Knot tying and splicing is a lost art and i have watched many an otherwise competent man make an ass of himself trying to secure a load on his truck or otherwise use knots. If you can learn a bowline, clovehitch, and half-hitch then you are way ahead of most folks. The only people i know other than fellow fisherman/mariners who know how to use knots are former Boy Scouts ETA: As per the fancy/expensive stuff(braided, samsom,etc) the Co. that makes it usually provides splicing instructions for that specific type of lay. If anyone wants to know any specific knots post requests here and i will scan and post instructions and pictures. |
up and over %50 for some knots. A GOOD splice is stronger. If anyone wants to know exactly how much a particular knot lessons the SWL(safe working load) i can post the loss of strength. |

WOW! My grandfather (died in 1984 at the age of 88) worked in the oilfields all his life in the Oklahoma/Indian Territory areas. He showed me how to splice rope when I was too young to remember how. He said that on the old oil rigs, everything was geared off of a tow motor that was set up near the rig and the power was transferred to the gearing by ropes and belts. He said that a good driller could splice a rope into a continuous circle so well that you could not tell where it began and where it ended. Another lost art. |
i'd love to see those |
I think you need to throw a taut-line hitch in there too. I learned knots when I was a boy scout. It was one of the first things that they taught us. I think I was about 12 when I learned them. I still use them. I taught myself how to braid. Not just flat braids, but round braids also. |
No Problem, off to the bookshelf to get some numbers for ya. |

Strength -- This refers to how a knot weakens the breaking strength of the line. The twists, loops, and turns of a knot place unequal stress on the line which reduces the line's breaking strength. In general, knots reduce a line's breaking strength by about 50% (Jacobson 1999). Knots in which the line "bends" back on itself are weaker in general than are knots without bends. For example, the clove hitch (with no bends) has a breaking strength about 75% of the line's rated strength. In contrast, the square knot has a breaking strength only 45% of the rated line strength. a few Double carrick bend 71% sheet or becket bend 65% fishermans knot 59% square knot 54% double bowline 69% bowline 65% overhand 49% still looking for some more. link to related info. a bit technical for this discussion though www.caves.org/section/vertical/nh/50/knotrope.html |
| I don't see anything like the splice we used on 7/8" wire line on the oil rig. I don't recall it very clearly but basically the strands of a 3-4 foot section of each piece of line was pealed out and each strand cut to a different length then wound back into the twist so that each end butted together at a different point in the splice. This might only work with steel cable though I've done something similar with yarn. |
i believe what you are refering to is called a long splice. It is done in the manner you describe so that it will pass through the shives in a block. It is not a wire rope specific technique |

The only people i know other than fellow fisherman/mariners who know how to use knots are former Boy Scouts +1 Many thanks for posting that. I had forgotten how to do some of that stuff since I don't use it everyday anymore. I am a master of the water knot and that will help eliminate some of that. water knot= a knot you piss all over yourself trying to untie water knot also = the reason serrated blade knives were invented. |

here is one on knot tying that someone posted last year. thought it'd be a good one to add here as well. www.animatedknots.com/index.php?LogoImage=LogoGrog.jpg |
