    When I use tapered bands, I always get the tear at the tie near the pouch, now I realise that as this is the most stressed point it is where the tear is most likely.<br>I would like to find any ways of reducing this without reducing the stretch - sometimes I only get about 100-150 shots at the moment, there is also quite some variability between bandsets so it feels like i'm doing something that is not ideal.<br><br><br>Bands are double TBG 32mm to 16mm - free length after drawing a few times is 21.5cm (fork tie to pouch tie} 112cm draw, i think thats 5.3* stretch<br>Tied both ends with strips of TBG<br>Ammo 12mm lead<br><br>The bands always tear on the inside folded band<br><br>My thoughs at the moment are: Maybe I wasn't carefull enough with the roller cutter<br> A poor pouch tie - can't see why<br> Use more talcum powder<br> Maybe try cutting the bands so that the narrow part is a couple of cm in front of the fork - doable but a pain<br><br>Anyone have any usefull insights on this ?<br><br><br><br>Sorry for the poor photos below<br><br><img src="http://i12.servimg.com/u/f12/17/99/08/66/img_0410.jpg" border="0" alt=""><br><img src="http://i12.servimg.com/u/f12/17/99/08/66/img_0411.jpg" border="0" alt="">

    I see/read no reason for such tears, maybe you have a blunt cutter blade or you weren't careful cutting? I had a tiny dent in my cutter blade and that caused tiny little bad spot and it teared there.

    yes usually most of the time ... use talcum and don't stretch too much when tying ... I use extra talcum to (lube) this area at the beginning of a shooting session ...

    There are several ways you can make your bands last longer ...<br><br>- less taper<br><br>- fold the short ends in such a way that they do not touch the edges of the "active" bands<br><br>- cut the short ends in such a way that they do not touch the bands with 90° angle, but a wider angle (you sort of "undercut" the short ends)<br><br>- do not use the same rubber for wrapping and tucking that you use for the bands. I tie my TB Gold and Silber with TB Blue, it is a lot softer and will not be as hard on your bands. The thinner rubber is also much lighter and can be a real miracle cure if you suffer from handslaps.<br><br>- I also use "wrap sleeves", my own invention. I pull the short end of the bands through the pouch, do points two and three and then, before I tie the highly tensioned rubber strip around it, I take a little bit of rectangular, thin rubber, about 5mm wide and so long that you can wrapp it round the bands just about 1,5 times with very little tension, and place that rubber between the bands and the rubber strip. It protects the bands from the edges of the thin rubber strip that has gone "hard" with all the tension and cuts up your bands.

    These are some very good tips, that pouch sleeve sounds like it will also come in good hand with string tied bands

    I think it works, too. I have recently gotten several hundred shots out of some super cheap latex "Thera"band knock-off from ebay (1,99&euro; for 2x1,5m). Btw I made a mistake, I posted that on SSF before and there I called them "wrap sleeves" not pouch sleeves. Edited my post to clear up any misunderstandings.

    thanks all, I'll try wrapping less tightly to start with and take more care with the tails. As the inside band is always the one that goes first, that one is probably compressed more, maybe i should try and roll the bands at the ends and not fold them, so that the edges are not exposed and rubbing.

    i recommend this. <a href="http://slingshotforum.com/topic/14370-attaching-flat-bands-to-pouch-with-1745-tubes-video/" target="_blank" rel="nofollow">http://slingshotforum.com/topic/14370-attaching-flat-bands-to-pouch-with-1745-tubes-video/</a> its a really great attachment method. i use a variation of it and it is the only one i use.

    I just tried the wrap sleeves on a set of half looped 2050 dankungs, it was breaking at the point where the loops begin in 3 sets. No breakage so far and I have shot it at least a hundred times. <br>But coming back to flatbands, I have experimentally tied a set of bands on my girlfriends like here <a href="http://slingshotforum.com/topic/19893-attaching-pouch-better-method-of-folding-bands/?hl=%2Bfolding+%2Bbands" class="postlink" target="_blank" rel="nofollow">http://slingshotforum.com/topic/19893-attaching-pouch-better-method-of-folding-bands/?hl=%2Bfolding+%2Bbands</a><br>It seems to work so far but I don't think she has shot very much with it yet.

    tapered bands are bands that are wider at the fork than at the pouch

    I bought a tire and cost me 17E which I think is just too much for rubber in Serbia. <br><img src="http://www.lukovi.in.rs/Images/Pracke/Theraband%20Gold%201.jpg" border="0" alt="">
