    I tested the arrow tonite... way too powerful. <br><br>Fired it against a T-Shirted foam block. The syringe went in all the way. But the shocking part was that the plunger broke the entire syringe front clean off, spraying the cherry juice over the T-shirt...<br><br>Have to try again with weaker rubber. <br><br><img src="http://i42.servimg.com/u/f42/16/32/46/92/syring12.jpg" border="0" alt=""><br><br><img src="http://i42.servimg.com/u/f42/16/32/46/92/syring13.jpg" border="0" alt=""><br><br><img src="http://i42.servimg.com/u/f42/16/32/46/92/syring14.jpg" border="0" alt=""><br><br><img src="http://i42.servimg.com/u/f42/16/32/46/92/syring16.jpg" border="0" alt="">

    Don't change the tubes, add some toothbrushes at the muzzle to increase drag.<br>

    What about using a metal shaft? Machine it to fit in the syringe body so you can ditch the plunger all together. I still think you're going to run into the plunger action failing due to hydraulic pressure. The needle won't release the liquid fast enough and it will act like a shock on a vehicle. Ending with the needle body going boom. Just thinking out loud over coffee! <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2"><br>Maybe a custom machined needle. Metal body and plunger, as well as a bigger metal needle tip. Big enough that the liquid can evacuate with the force of the plunger pressure. Needle could be a couple mm stainless tube. After all, you don't need to worry about a needle that big hurting.......you are going for a kill anyway! <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2">
     
  7. Check out the book "Blowguns - The breath of death", I know ominous title, but there are a few ideas in there that may help. I am no good a drawing and don't have a scanner so I can't post pics from my copy <img src="http://illiweb.com/fa/i/smiles/icon_sad.gif" alt="Sad" longdesc="3">

    <span class="postbody"><br><br>That sounds good. File the end one sided like a real needle. Much better penetration and opens the surface like a knife slit rather than a punching effect of a conical tip. The tube to cover the hole it a great idea. Then you can have a bigger hole and no leaks. As long as the hole is not past the point of causing the tip to bend. <br>Food coloring as the test liquid and a fresh schweinchen leg would be a good test. And you can still eat it after ! <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2"></span>

    Have put on some light Thera Tube Yellow, for indoor shooting.<br><br>A lot of fun! Accurate, easy to cock just with your hands (pistol butt pressed against the chest), and harmless enough so you can use a cardboard box stuffed with paper as a catch box/target. <br><br>Now that the days are so short (it is always dark when I come home from work), indoor shooting is great. <br><br>The bands and string hold forever, with these light TTY bands - the brutally short double TTS breaks quickly, and the string suffers too. All that draw weight. <br><br>Also, got some more bolts today. Great deal - about 50 cents a piece!<br><br><img src="http://i42.servimg.com/u/f42/16/32/46/92/tby10.jpg" border="0" alt="">
     
  11. That little thing deffinatly came out cooler than my little crossbow (I bought a little pistol off amazon), probably cheaper too lol. Can't wait to see some more of your spy arrows for it.

    Here is the next iteration, im real life. Much smaller.<br><br><img src="http://imageshack.us/a/img842/5352/mini1z.jpg" border="0" alt=""><br><br><img src="http://imageshack.us/a/img59/9599/mini2go.jpg" border="0" alt=""><br><br>Actually, the draw length of both weapons is the same. The new one is just a more compact design.<br><br><img src="http://imageshack.us/a/img811/450/mini6v.jpg" border="0" alt=""><br><br>I also made an arrow that allows me to put a percussion fire cap (from my civil war Gallagher carbine) onto the tip. The shaft is hollow. I leave it to your imagination how that cavern can be filled... <br><br><img src="http://imageshack.us/a/img5/2329/mini3ff.jpg" border="0" alt=""><br><img src="http://imageshack.us/a/img849/433/mini4e.jpg" border="0" alt=""><br><img src="http://imageshack.us/a/img22/1844/mini5n.jpg" border="0" alt=""><br><br>This may be the most compact pistol crossbow I have seen.<br><br><img src="http://imageshack.us/a/img534/3018/mini7n.jpg" border="0" alt=""><br><br>Here is a little video (sorry, indoors mostly...

    Very nice pistols.<br>The small one is very compact but i like the magnum version more. It is maybe because i am a small guy( +- 1,65m), i have to compensate. <img src="http://illiweb.com/fa/i/smiles/icon_razz.gif" alt="Razz" longdesc="9"><br>Are your pistols so powerful as the pistol crossbow you show in your vid?<br>You really have a great imagination for creating all those great weapons. I wonder where you got the inspiration from. So, once again, you did a wonderful job on those little babies. <img src="http://illiweb.com/fa/i/smiles/icon_cheers.png" alt="cheers" longdesc="28">

    The "magnum" version is very comparable to the commercial crossbow in terms of power, but of course the commercial one can't fire crazy ammo. And it is very bulky.
