    Here is my latest work... a repeating slingshot crossbow, shooting 9 inch nails. <br><br>This is in continuance with my Chu-Ko-Nu based design line. This time, it is bigger than the pencil shooter, but a lot smaller than the chest mounted spear launcher. <br><br><img src="http://i14.servimg.com/u/f14/16/32/46/92/9inch210.jpg" border="0" alt=""><br><br>The ammo is - nine inch (23 cm) nails. Those are cheap, about 8 Euro-cents a pop (10 Euros for 120 of them). Of course you have to cut of the head, done in about one minute. <br><br><img src="http://i14.servimg.com/u/f14/16/32/46/92/9inch110.jpg" border="0" alt=""><br><br>The repeating action is done by pressing the butt against the chest and pulling back with both arms, like in a rowing machine. This is needed as you need a lot of draw fiorce to throw the heavy nails - each weighs 76 gramms (1276 gr). The magazine fits ten of them. <br><br><img src="http://i14.servimg.com/u/f14/16/32/46/92/9inch310.jpg" border="0" alt=""><br><br>With a bit of extra effort, you can very easily enhance the tip by sharpening it. I even hardened the tip of this one. <br><br><img src="http://i14.servimg.com/u/f14/16/32/46/92/9inch410.jpg" border="0" alt=""><br><br>Ot works great. I may add more rubber soon, but already this is very effective. Like a Chu-Ko-Nu, but more compact and with a trigger!<br><br>Video will follow shortly!

    Looks great fun to shoot, since the arrows have no fins how good is it at a long distance? Great work as always

    Fins are really not needed for heavy bolts. Medieval crossbows never employed them. <br><br>It is a common misconception that fletching is needed for accuracy and a straight flight. Look a olympic javelins!<br><br>Also, this is very much a short distance weapon. "Nailing zombies" becomes a new meaning!

    Well, it has much more draw weight, and uses heavier ammo. Yes, it is much more powerful. Plus it is a repeater, 10 shots can be fired in no time.<br><br>

    Jeorg may I ask you what's the diameter of those nails? I am seeking for bolts for my crossbow and that weight and the cheap they are, is what I was searching for a while and didn't figure out it could be that simple ...

    Nails are 7,6mm (.30").<br><br>In the video, I used 2 strands of 6,2 x 11 cm TBG per side. Since then, I added TBG blue, same sizes.
