    Good procedure, wrong glue.
    Super glue is stiff and will create a blob at the rope end that can jamb in a rapide when you pull the rope.
    It can also weld the sheath to the core so severely that if the sheath slips a little (as it is prone to do on dyneema core ropes)
    then you will not be able to milk the sheath off the end- leaving a bunched up blob that will stick in your device or a rapide.
    I use the same procedure but with VINYL cement.
    This is what Bluewater Ropes recommends.

    Can you be more specific on the glue?

    I'll do a write up/tutorial on this when I get a minute.

    Todd is right, CA (super) glue is not ideal.

    I use Aquaseal or Seamgrip.

    Aquaseal is kinda sticky though... seems like it might cause problems.

    A 3/4 long section of it has never been a problem for me.

    I'll show ya ;)

    I've used melted polyester from those blue-collar type ropes, and that has worked well. Drip it on there, smooth it out.

    There are several ways to do it based on a couple considerations.

    Is the rope new?
    Are you just finishing an end on a new rope?
    Are you cutting off of a spool or longer rope?
    Are you just refinishing a rope whose sheath has milked down?
    Do you want to indicate the length?

    Basic procedure:

    Mark the location of the cut

    Wearing gloves, apply glue and knead it into the sheath[​IMG]

    Allow to cure for a couple hours and cut using a sharp* knife

    I have used Bootboy's technique to great success. None of the ends of the Sterling C-IV i cut have come undone or frayed. I also squeezed a bit of the aquaseal into the end of the rope to cap the end.

    Taking care to finish a rope end this way can save a lot of grief on a 'marginal' pull.
    Like on a long rappel anchored by an extended sling,
    when the sling flips and the pull side of the rope is on top of the link making a pinch
    and maybe the ropes are twisted around each other..
    In this circumstance ANY additional resistance (like a badly finished/blob rope end) could leave you stuck.

    I hope that is not a hardwood FLOOR...
