    Hi guys,<br>today arrived to me thera band gold, i cutted band, made pouch, but i cant fix with constrictor (or double) knot the end parts of bands to the pouch:<br>when i stretch the bands, the bands simply fly away <img src="http://illiweb.com/fa/i/smiles/icon_biggrin.png" alt="Very Happy" longdesc="1"> the knot at the pouch is not good (but i red and followed all joerg's manual). I used a little rope, but i don't think this is the problem.<br>Why that happen?<br>Should I use little pieces of bands (as at forkside) instead rope?<br><br>Thank u<br>Otta

    I prepare the constrictor knot and slip it over the bands. Then I stretch the band a bit and ask a second person (in the most cases my wife) to pull at the ends and tighten the knot.<br><br>Sometimes I use a strip of thera band to attach the bands to the pouch. <br><br>Some people made themselfes a jig with two vices so they can attach the pouch with the two side of the bands between them. I remember a video from gamekeeper john on youtube.

    @DaveSteev, it works, if i pre-stretch bands before closing the constictor knot the knot is really strong!<br>Now i'm "evocating gods" <img src="http://illiweb.com/fa/i/smiles/icon_wink.gif" alt="Wink" longdesc="15"> for do the same thing at forkside, maybe i've to pre-stretch the bands there too to don't do them fly away like at pouchside!<br><br>thank u<br>Otta

    Hi,<br>I think you better use strips of latex bands to tie it at the fork.

    STring will never work as well as rubber band, because your actual bands become thinner as you stretch them and you rknot becomes looser. Maybe it will work with prestretching, but not as well as rubber bands.

    well, string works very good if you prestrech it, better than rubber bands in my case

    Three possible reasons for your failures.<br><br>1. Error in tying the constrictor knot<br>2. Wrong string (I use polypropylene string)<br>3. Constrictor knot not pulled hard enough<br><br>With a constrictor knot that is pulled hard enough, no prestretching is necessary. The knot bites so deep and hard into the rubber that there is no slippage.

    Hi, There is a way of using 550 paracord to tie a very compact constrictor knot. First, cut a piece of cord approximately 2 meters or yards of cord. Then pull out the 7 fine white strands of string from center of the cord. This may take a minute because the interior strands bunch up inside the outer tube of the paracord as you pull them out. You can discard the white strands or use them in another project. Now take the outer tube or mantle of the paracord and use it to tie your constrictor. The mantle is very elastic and ties a very tight and FLAT knot. I think it will do less damage to the latex than the finner cords. Let me know if anyone tries this and how it works for you. Thanks, Chris

    Hi, Good questions. It's hard to convey with words what video and pictures can do. Yes the mantle is heavier than one of the strands. It has a finer weave and I believe it to be more abrasion resistant. The knot ends up being about 3/8 inch wide. You can separate the mantle from as much cord as you like. However, if you are planning on making a lot of lashes you waste less cord by decordicating more paracord at once. I have tied the knot this way a lot in a different context. Recently, I have made a pouch set like this. It seems to be working fine for now. I used latex tubing and alternated between pulling on the tag ends of the constrictor knot and streaching the both pieces of tubing on each side of the knot. I did this back and forth until the knot was was very tight and the two paralell cords on the bottom of the knot are tight against eachother. I'll try to post some photos.

    <span class="postbody"><br><br><br>A constrictor knot would not tighten on paracord? Was is wet of greased or anything? I have never had a problem with that knot holding paracord before. There must have been an outside issue.</span>

    stretch the band at pouch before thighten the knot i think is the better way (after more than 500 shots the pouch knot is still tha same)<br><br>... of course i use ONLY costrictor knot, the best always <img src="http://illiweb.com/fa/i/smiles/icon_biggrin.png" alt="Very Happy" longdesc="1">
