I have been thinking about how to make a slingshot crossbow shorter, and also easier to cock. <br><br>I saw a video about a folding speargun by a Spanish speaking inventor a while ago. While it was impractical to use his mechanics, I took his break-barrel idea and changed it for a ball shooter. <br><br>The result is a powerful, short, easy to cock and accurate new weapon.<br><br>Folded:<br><br><img src="http://i75.servimg.com/u/f75/16/32/46/92/foldin10.jpg" border="0" alt=""><br><br>Unfolded and cocked:<br><br><img src="http://i75.servimg.com/u/f75/16/32/46/92/foldin11.jpg" border="0" alt=""><br><br>The bands are attached to both a leather pouch and a length of paracord. The paracord is held back by the sear/trigger part.<br><br><img src="http://i75.servimg.com/u/f75/16/32/46/92/foldin12.jpg" border="0" alt=""><br><br>The entire trigger/lock module is able to swing up and down, in order to follow the bands while the weapon is cocked/unfolded. This prevents chafing on the paracord and makes the drawing much more smooth. <br><br><img src="http://i75.servimg.com/u/f75/16/32/46/92/foldin13.jpg" border="0" alt=""><br><br>The lock for the folding pivot is very simple. It is held under tension with rubber (what else), but the rubber is not needed for holding back the force. Sear and pivot are in line, rock solid. <br><br><img src="http://i75.servimg.com/u/f75/16/32/46/92/foldin14.jpg" border="0" alt=""><br><br>The weapon only weighs about 600 gramms (1,3 lb), and is about 65 cm long (folded). I may add a red dot and a folding shoulder rest later on. <br><br>Here is the video:<br><br><embed pluginspage="http://www.macromedia.com/go/getflashplayer" src="http://www.youtube.com/v/YhS35kOsmyU" width="425" height="350" type="application/x-shockwave-flash" wmode="transparent" quality="high" scale="exactfit"></embed>

the moment i read yout title i thought:"break barrel", and it was one, awesome crossbow once again, well thought out and well made, i really like this one, tho maybe i would have liked it a little more when the barrel would've folded down shotgun style

I don't know how you keep coming up with interesting ideas like this. There's always something new and novel on the Slingshot Channel. Very impressive.

I cant wait to see this, I am sitting with YouTube open just waiting for it to finish uploading <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2"><img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2"><img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2"><br>I have thought about a design like this but the stumbling point was always the release which you fixed with the paracord, Genius!

Nice.<br>Wouldn´t it be possible, instead of folding and a more complicated lock, to make the front part of the barrel slide back into the part with the handle?<br><br>So you add some kind of footrest on the front and cock it by simply pulling the front part out and lock it there somehow.

<span class="postbody"><br><br>I have seen such constructions before, the concept works. But I like the easy draw weight towards the end of the semi circle, and also I like that I don't have to put the muzzle to the ground, in this kind of weather. </span>

Amazing slingshot crossbow!!! The one i liked the most was the pump action crossbow... until now.<br>It seem to be really powerful, probably more than the bullpup. I just love it!<br>You are an incredible man. Thanks for the video.<br><img src="http://illiweb.com/fa/i/smiles/icon_cheers.png" alt="cheers" longdesc="28">

Hello to all! I am new to this forum so bear with me. I was awestruck by this design and think it would be perfect for my bug out bag setup. I would like to know if and when the blueprints will be available for this design. My hat is off to you JoergS, you are a natural designer.
