                    used rope eye splice double braid Class I
  Class I ropes are made from any or all of the following fibers: olefin, polyester, or nylon.
  This is an eye splice which can be performed on used rope. This is an all-purpose
  splice techniqe designed for people who generally splice used rope as frequently
  as new rope. It retains up to 90% of the average new rope strength and in used
  rope up to the same proportion of residual used rope strength.
  You may wish to read the supplemental information, "Special Tips for
  Splicing Used Rope" (page 8), before beginning.
  Splicing used rope can be made easier by first understanding the rope condition.
  Natural shrinkage has occurred caused by water and heat. In addition, the cover
  yarns have often been abraded. Soak the section of rope to be spliced in water
  for several minutes  this lubricates and loosens fibers.                                                              1 layer of tape

            Tape end to be spliced with one thin layer of tape. Then,                                                                          1 fid length
            measure one tubular fid length (2 wire fid lengths) from end
            of rope and mark. This is point R (Reference). From R form                                                                              -or-

            X where you extract core from inside the cover. If using a
            thimble, form the loop around the thimble.
            Tie a tight slip knot approximately five fid lengths from X.
            This must be done!
                                                                                                                                                        Tie a slipknot about 5 fid length from "X"

               extracting the core
             Bend rope sharply at X. With the pusher or any sharp tool such as
             an ice pick, awl, or marlin spike, spread the cover strands to expose
             core. First pry; then pull the core completely out of cover from X
             to the taped end of the rope. Put one layer only on end of core.
             Tip: After marking cover untape end of rope, grasp end of core,                                                                        Prying out the core
             and slide back cover pulling out core. This loosens and bunches
             up cover strands in the area of Point X and makes it easier to open                                                                                       R
             up cover strands for extraction. Also, thoroughly loosen 3-4 strand
             pairs at X to assure a large and flexible hole for extraction, see left.
                                                                                                                                                                                                 1 layer of tape
             To assure correct positioning of Mark #1 do the following:                                                     cover
             Holding the exposed core, slide cover as far back towards the
             tightly tied slip knot as you can. Then, firmly smooth the cover
             back from the slip knot towards taped end.                           Mark 1
             Smooth again until all cover slack is removed.

             Then, mark the core where it comes out
             of the cover. This is Mark 1.
                                                                                                                               marking the core
                                                                                                                             Again slide cover toward slipknot to expose more core.
                                                                                                                             From Mark 1, measure along core towards X a distance

10          finishing the splice

           Now untie the slipknot. If eye is not the right size, carefully check Steps 1 through 9.
           If a hollow spot appears at the throat this means that the core tail was cut off too short.
           Do not worry as this does not affect the splice performance nor its strength. Reason:
           the total load of an eye splice is split between its own two legs. Therefore, each side
           of the splice only has to support 50% of the total load. The braided cover alone can
           handle this load factor.
           You should whip the eye splice starting at base of throat
           of eye, especially if rope is 1" diameter and larger.

The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
