I've made a Moorhammer type slingshot and I'm having issues with keeping the bands on it. The bands hold tight during a draw, but the forward momentum yanks them out of the theraband strips holding it onto the frame. There's a deep notch around the fork, but that doesn't seem to help. I've remounted them a dozen times and rarely get more than 2-3 shots out of it before the bands pull loose. Any idea what I'm doing wrong? There's three bands per side of Theraband Silver... should I tone it down a bit?<br><br><img src="http://i49.servimg.com/u/f49/17/59/95/19/img_2010.jpg" border="0" alt="">
<div>hmm... this is somethign I have never encountered... maybe use string at pouch end, use thinner , more weightless pouch material, and tie the bends with stronger band at the forks, IE : gold thera band strips?<br><br>triple silver is pretty strong tho...<br><br>maybe lower attachment point on the forks?</div><div class="clear"></div><div class="signature_div"> <br><a href="http://voiceofquran.info/mp3_files/german_quran_mp3/001.mp3" target="_blank" rel="nofollow">http://voiceofquran.info/mp3_files/german_quran_mp3/001.mp3</a><br>my website! <a href="http://wigglesworthswoodwork.webs.com/" target="_blank" rel="nofollow">http://wigglesworthswoodwork.webs.com/</a><br>For your spiritual well being ( more important than anything ) <a href="http://muttaqun.com/" target="_blank" rel="nofollow">http://muttaqun.com/</a> </div>
I just tried wider and longer TB strips last night, same problem... I will look into lightening the pouch material. It stands to reason that less forward moving mass will decrease the likelihood of a strong forward tug.<br> The thing's a real powerhouse so I hate to remove a band from each side, but if it means I can shoot more than twice before remounting the bands I might have to give up a little power.
Are you stretching out the attachment rubber bands enough? They need to be really tight. You can also keep the "wraping zone" wider, so there is more surface = friction.

This is my first slingshot, so I'm still feeling out the process. I'll use some inch-wide tb to wrap it and see what happens. The thing that it's been doing is rolling the wrap bands down, allowing it to pull out. Maybe the wider bands won't roll.<br><br>bullshot... One of the first things I tried was sanding off the varnish, roughing it up with some 100 grit paper. That did improve things a bit.</span>
Yes! I cut some bands almost as thick as the tension bands to use as attachment bands. I put the slingshot in a padded vice and tightened the heck out of them in an inch wide area on the forks. <br><br>I'm up to 25 shots out of it without band slippage. <img src="http://illiweb.com/fa/i/smiles/icon_cheers.png" alt="cheers" longdesc="28"> High fives and fist bumps all around, guys.
