    I will go to South Carolina on Oct. 13th in order to film a test episode for a US TV channel. If they like it, I may end up having my own show!<br><br>We will only have three days for the filming, so I have to finish the two weapons we plan on covering here. Then we will "fake" the making off. <br><br>The first weapon will be much like my bullpup arrow shooter - but it will have two shots. Plus, it will have to be a lot stronger as the "customer" is a guy who wants to go hunt nutrias with it. Tough little creatures. <br><br>Therefore, I had to increase the "barrel" length and also make the string stopper stronger. The bands will have enormous speed when they hit that stopper, that's why. <br><br>I already finished the lock system - I am quite proud of the design as it is very small, yet strong.<br><br><img src="http://imageshack.us/a/img341/5517/apshooter1.jpg" border="0" alt=""><br><img src="http://imageshack.us/a/img440/8899/apshooter2.jpg" border="0" alt=""><br><br><br>The weapon will hold the arrows at the sides, of course with the help of toothbrush heads (found some at a penny store for 40 cents a piece).<br><br><img src="http://imageshack.us/a/img854/4849/apshooter3.jpg" border="0" alt=""><br><br><img src="http://imageshack.us/a/img42/6411/apshooter4.jpg" border="0" alt=""><br><br>Here, you can see my original drawings for the lock, and also for the trigger/pistol grip assembly. <br><br><img src="http://imageshack.us/a/img838/2946/apshooter6.jpg" border="0" alt=""><br><br>Note that the triggers have to be quite long, in order to give enough leverage for the heavier trigger pull - needed for the strong bands I plan on using. <br><br><img src="http://imageshack.us/a/img827/3396/apshooter5.jpg" border="0" alt=""><br><br>Also, the front trigger fires both "barrels". So the shooter has a choice. <br><br>The weapon will be brought to the US "raw", means, in shooting condition, but entirely without any finish. Nathan Masters, who has agreed to participate in the show, will be responsible for the looks. I am sure he will do a great job.<br><br>This will be a great shooter!<br><br><br>

    Wow the weapon is looking great. Also the mech is great.<br><br>I need some minutes to understand the mechanism.Where do you get the ideas for your mechanisms? Can we watch the test episode in the internet?

    Cool. I think its going to be a great weapon when finished. But im afraid I wont be able to see the show if they decide to make it... Also, faking the making of dosent feel so "Joerg".

    The mechanism is very easy, the hooks that hold back the crossbow strings are curved (90 degrees) so when you pull on the attached paracord, the hooks swing out and the shot falls.<br><br>One of the hooks is higher than the other one, in order to make the lock more compact.<br><br>Ideas come easily to me, I don't really need inspiration. I simply think about ways to solve a mechanical problem, then I start to draw some sketches. <br><br>The test episode will be financed by the network, so it will be their intelectual property. I have no idea what they will do with it. If we get to do six episodes, then they will probably include that material somehow. <br><br>And some amount of faking is really normal when you work for the TV. It is impossible to do real work when the camera crew is present. The lighting, the constant "one more time" thing...

    Progress.<br><br>The weapon is shooting now! The trigger/lock mechanism work like a charm. <br><br>Will have to make a shoulder rest, a cheeck rest, a handle for the left hand and a scope mount tomorrow.<br><br><img src="http://i32.servimg.com/u/f32/16/32/46/92/apshoo10.jpg" border="0" alt=""><br><img src="http://i32.servimg.com/u/f32/16/32/46/92/apshoo11.jpg" border="0" alt=""><br><img src="http://i32.servimg.com/u/f32/16/32/46/92/apshoo12.jpg" border="0" alt="">

    Awesome!<br><br>How do you make the slot/rail for the arrow? Do you glue two wooden blocks together with a thin piece between? Or do you use a chisel?

    <span class="postbody"><br><br>Two wooden rods, 1cmx4cmx95cm, with a smaller one (1cmx0,5cmx95cm) in between.<br><br>You need to select the rods carefully, many aren't straight. <br><br>Chisel is hard work, the groove needs to be deep enough for the fletching (1,5cm). And of course the groove has to be 100% straight. Using my method is a whole lot easier, and probably more precise no matter how good your chiselwork is. <br><br>This weapon is as compact as can be, really.</span>

    That looks so absolutely awsome already! I'm looking forward to see it painted and shooting!

    The weapon is basically finished now.<br><br>I attached a G36 five Euro scope, of course adjustable.<br><br>Butt and cheek rest is there now, too, as well as the foregrip. <br><br>I did not use much glue this time, as I will have to disassemble it for the filming (so it looks like we are just making it). This means many screws.<br><br>Total weight is just under 2 kg (4,4 lb), with bands but without arrows. Total length is 1 meter. <br><br>It is amazingly accurate! Can't wait to see what Nathan will do to make it beautiful. I will do a video tomorrow, so you guys can see it.<br><br><img src="http://i32.servimg.com/u/f32/16/32/46/92/apshoo13.jpg" border="0" alt=""><br><img src="http://i32.servimg.com/u/f32/16/32/46/92/apshoo14.jpg" border="0" alt="">

    Flippinout-Nathan?<br><br>I bet he has something up his sleeve. Would be awesome.<br><br>What does "amazingly accurate" mean in numbers?<br><br>Let´s say you put it in a vise and aim at a target 10 meters away. Would 9 out of 10 arrows land in a 50cm diameter circle for example?
