    THE NEWEST VIDEO:<br><a href="http://www.youtube.com/watch?v=UEK-KhPpH_c&feature=youtu.be" target="_blank" rel="nofollow">http://www.youtube.com/watch?v=UEK-KhPpH_c&feature=youtu.be</a><br><br><br><br><br><br>Old Video: <a href="http://www.youtube.com/watch?v=w3Ci4niv3V0&list=UUeIZckFcnSTHjmVk8uB07gg&index=1" target="_blank" rel="nofollow">http://www.youtube.com/watch?v=w3Ci4niv3V0&list=UUeIZckFcnSTHjmVk8uB07gg&index=1</a><br>-----------------------------------------------------------------------------------------------------------------------<br><br><br><br><br>Hey Guys,<br>When I was about 11 I welded myself a nice balista. A Balista is a Roman Weapon which was widely used firing mostly bolts, and arrows. I made one of the two bands tonight, and its just enourmous, since it is consisting of 3 meter elastic band layered 6 times with a Draw wheight about 75 Kilogram:<br>(Battery as a size comparison)<br><br><br>[​IMG]<br><br>Tommorow I will make some pics of the actual balista. JUst some facts its width is about 90 Cm and its length about 1,10 meters. Its a solid iron construction. I would like to know what you think about this so comment <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2"><embed pluginspage="http://www.macromedia.com/go/getflashplayer" src="http://www.youtube.com/v/UEK-KhPpH_c" width="425" height="350" type="application/x-shockwave-flash" wmode="transparent" quality="high" scale="exactfit"></embed><embed pluginspage="http://www.macromedia.com/go/getflashplayer" src="http://www.youtube.com/v/UEK-KhPpH_c" width="425" height="350" type="application/x-shockwave-flash" wmode="transparent" quality="high" scale="exactfit"></embed>
