If your flying line is Kevlar, the only way of rejoining without serious loss of strength is to splice the pieces together. Dacron line can be tied together using a blood knot, or a barrel knot. Spectra is tough to tie because it is slick. You might try a blood knot or a double uni-knot. The uni-knot is a fishing knot. A good book on fishing knots is "Practical Fishing Knots" by Lefty Kreh and Mark Sosin.

The type of line, what length it was to start, and about where >it broke would be helpful information.. Marty has already suggested splicing if you're using kevlar. I would suggest splicing for spectra, though it's almost impossible with lines < 150#. Splicing is a rather nifty trick that takes advantage of the fact that your lines have a hollow braid. It's done with a tool that looks like a miniature latch hook, usually referred to as a 'fid'. Short ones are fairly common (I believe you can find them at sewing stores). High Fly also used to sell them, and you might be able to find one at another kite store. Premier Kites has just started making sleevers and fids out of surgical steel, about 1' long, These are probably the best such tools currently on the market. They blow away any other sleever/splicer you've used. In any event, the basic technique is: insert the fid in through the side of one piece of line an inch or two from the end, and guide the end of it out through the cut end of line I. Use the fid to pull the end of line II through the core of I and out through the side. At this point, the end of one cut line disappears into the center of the other cut line, and then exits through the side. Now reverse the procedure--insert the fid into the side of line II (at a spot an inch or so before it enters line I, and then bring the fid _back_ out the side, right at the spot where II enters I. Use the fid to pull the loose end of I into the core of II and then back out the side. Smooth out the splice and then trim the loose ends of line where the exit from the sides. And that's it! The beauty of this splice is that the harder your kite is pulling, the tighter the braid becomes, and the tighter the spliced section grips itself. I've got a set of 150# spectra that I spliced just under 3 years ago; I've flown a Tracer in 20mph winds on it, with nary a problem. And as you might expect, the splice is very smooth once the loose ends are trimmed, so you don't have to worry much about your lines sliding through each other when twisted. As should be obvious, this is almost impossible to do with smaller diameter lines simply because you can't get the fid to slide through the core. Particularly if the line is already a bit old and stretched (with a tightened braid). Jeff -- |Jeffrey C. Burka | "Fairies are the perfect people to do this | |(suffering Bad Grammar) | sort of work.

For most applications I would use a good 'ol square knot. Never gave me trouble. But then again I never fly kites with more than about 75# pull. And the winds here are a bit too gusty to guess exactly how much continuous stress a line would undergo. = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Date: Wed, 23 Jun 1993 11:25:05 -1000 From: Wes_Voss@Novell.COM (Voss, Wes) Message-Id: <64D6282C01380070@MHS.Novell.COM> Organization: Division of Applied Sciences, Harvard University Subject: Knots...
