    since this weekend i shoot chninese Tubes again and i am very happy with this tubes!<br><br>they last much longer than Therabands, very quiet shooting, easy to make them and chance on the Slingshot !<br><br>here some Chronytest from today:<br><br>18/42 Tubes 7:6 Tapered <br>8mm steel 98ms<br>10mm steel 93m/s<br><br>20/40 tubes 7:6 Tapered<br>8mm steel 100m/s<br>10mm steel 83 m/s <br><br>the 20/40 are better for 8mm and the 18/42 better for the 10mm.<br><br>those are very good results for tubes! if you don´t want to shoot much faster than 100 m/s and you have no problem with a litte bit more draw weight, the tapered Tubes are very good for you.<br><br>the best speed i had at this test was 105m/s with 8mm and 101 m/s with 10mm steel! air temperature 12°C <br><br><a href="http://www.servimg.com/image_preview.php?i=84&u=16906761" class="postlink" target="_blank" rel="nofollow"><img src="http://i40.servimg.com/u/f40/16/90/67/61/img_1410.jpg" border="0" alt=""></a><br><a href="http://www.servimg.com/image_preview.php?i=85&u=16906761" class="postlink" target="_blank" rel="nofollow"><img src="http://i40.servimg.com/u/f40/16/90/67/61/img_1411.jpg" border="0" alt=""></a><br><a href="http://www.servimg.com/image_preview.php?i=86&u=16906761" class="postlink" target="_blank" rel="nofollow"><img src="http://i40.servimg.com/u/f40/16/90/67/61/img_1310.jpg" border="0" alt=""></a>

    Hi,<br>I also like shooting with tubes.<br>What kind of knot do you use?<br>Have you ever tried the new tapered tubes by Dankung?<br><br><a href="http://slingshotforum.com/topic/19061-dankung-2550-x-2062-tapered-tubes/" target="_blank" rel="nofollow">http://slingshotforum.com/topic/19061-dankung-2550-x-2062-tapered-tubes/</a><br><br>Zwillie

    Interesting method how to attach the tube.. What does it mean 7:6 ? From the video it looks much more like 1:2 (2 pieces ofr long tube, 1 piece of short folded tube)

    That is a pretty massive and heavy knot ... have you tried out my method of simply tying the tubes together with rubber strips, just like one attaches flatbands to an OTT fork? I wonder if that would be faster.

    For shorter tubes when it's difficult to tie the knot, I tried this (still not shooting with it, but I hope it will hold):<br><br>1) knot at the end<br><a href="http://www.servimg.com/image_preview.php?i=44&u=17729622" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/72/96/22/2012-119.jpg" border="0" alt=""></a><br><br>2) knot in the middle, don't tie still, leave it loose<br><a href="http://www.servimg.com/image_preview.php?i=45&u=17729622" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/72/96/22/2012-120.jpg" border="0" alt=""></a><br><br>3) push the end from (1) through the loose knot<br><a href="http://www.servimg.com/image_preview.php?i=46&u=17729622" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/72/96/22/2012-121.jpg" border="0" alt=""></a><br><br>4) and tighten <br><a href="http://www.servimg.com/image_preview.php?i=47&u=17729622" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/72/96/22/2012-122.jpg" border="0" alt=""></a><br><br>I hope it will work well.

    good ideas guys! <br><br>yes i try it with rubber strips as well ! and it looks fine i think my knot method is very fast but not so nice looking and waste of rubber.<br><br>this is also a rubber strips method but he made also a hole in the end:<br><a href="http://www.youtube.com/watch?v=MD6rcgEK3Og&feature=plcp" target="_blank" rel="nofollow">http://www.youtube.com/watch?v=MD6rcgEK3Og&feature=plcp</a>

    @Zwillie and Tobias ... I am really impressed with that pseudo-tapered tubes, I will buy a roll but I don't know which one (number) is the appropriate for my needs ... I usually use 10 to 15 gram ammo with a draw length of 110cm ... I would be very pleased to reach 65 to 70+ mps @ 25°C ... is that possible ? thanks in advance <br>Arturo

    Hi Arturo,<br>here I got the tubesizes.<br>You have to choose a tube which has the ringarea you can draw out.<br><br><img src="http://up.picr.de/12824403gb.jpg" border="0" alt=""><br><br>I got 3060 doubled here...hard to draw <img src="http://illiweb.com/fa/i/smiles/icon_silent.png" alt="silent" longdesc="25"><br><br><img src="http://up.picr.de/12824614eu.jpg" border="0" alt=""><br><br>It has about 85mm² ringarea, thats a lot.<br><br>Theraband gold is about 0,75mm in thickness.<br>So the drawweight is nearly the same as drawing a band of TBG in full width of 138mm.<br><br><br><br><br>1745 and tapered should be better for speed.<br>Zwillie
