Hi everybody. I was wondering, did anybody try to build a 2-1 pulley system to take advantage of strong but slow bands? I was thinking about using such a system with a lot of office bands, in some kind of slingshot crossbow. What do you think about the idea? Cause I think that if the bands are strong enough, the projectile should be launched faster than with just the bands themselves (especially with chained office bands).<br><br><a href="http://www.servimg.com/image_preview.php?i=1&u=18000218" class="postlink" target="_blank" rel="nofollow"><img src="http://i12.servimg.com/u/f12/18/00/02/18/2-1_pu10.jpg" border="0" alt=""></a><br><br>As you can see in my image (which is kind of a first draft, and is not well proportionned), the bands are placed in the "disadvantaged" place of the 2-1 system, so the strings pulling the pounch would be pulled nearly twice faster.
