    Check out the new mechanical release from <a href="http://www.dankung.com/emart/new-professional-release-aid-p-687.html" class="postlink" target="_blank" rel="nofollow">Dankung</a>. Very expensive, but it looks nicely made from aluminum alloy and stainless. Doesn't hold big enough ammo for Joerg, lol, but should be fine for most of us. <img src="http://illiweb.com/fa/i/smiles/icon_lol.gif" alt="Laughing" longdesc="7">

    Yeah, I'm actually debating getting one. I know I could make one for cheap, but not one this cool. I'm just not sure I wanna lay out the coin yet. <img src="http://illiweb.com/fa/i/smiles/icon_scratch.png" alt="scratch" longdesc="33"> We'll see. <img src="http://illiweb.com/fa/i/smiles/icon_lol.gif" alt="Laughing" longdesc="7">

    would be very interesting to se the inner parts.. I think it would be rather easy to copy that thing. but how does it work? has anyone an indea? maybe an explaining drawing?

    It's gotta be pretty simple. I would assume that all that needs to happen really when the thumb lever is pressed is that something is moved out from between the arms inside the shell, allowing them to rotate away from each other. I just can't picture quite how that happens, though.

    Yes! <img src="http://illiweb.com/fa/i/smiles/icon_cool.gif" alt="Cool" longdesc="6"> That's the basic idea. I think it must be something at least very similar to your drawing. I think there could also be a spring (or a couple springs) involved somewhere in there that return the trigger and "block" piece to their "forward" position.

    That one is very nice. Great design but as you said, expensive. When i saw the price i was instantly feeling sick. I just gonna keep using my fingers until i get old and got arthritis.

    <span class="postbody"><br>i think so too, we should all give like 5 euros and buy one, then open it and look at the insides so we could recreate it, but thinking of it makes me feel sad about my 5 euros and it makes my fingers feel underated</span>

    It looks a lot like bow release, caliper style. a couple of roller bearings mounted on the calipers, a wedge shaped block with a spring to push it towards the calipers and a linkage to pull the block away. my best guess.

    initially i wanted to make a pinky/ring finger supported lanyard loop out of paracord for my bow trigger release. then i took a deeper look at it and made this SIMPLIFIED sketch of it.<br><br><a href="http://www.servimg.com/image_preview.php?i=8&u=17552695" class="postlink" target="_blank" rel="nofollow"><img src="http://i45.servimg.com/u/f45/17/55/26/95/trigge10.png" border="0" alt=""></a>

    Hi MaddyMax,<br>the Dankung is made symetric in the arm -mechanism.<br><br>Think you can have problems in precision, because your left arm is heavier and with your releasefinger you influence the sideswing of this arm.<br><br>I think the pouche will get a little push from the left.<br><br>Hier your release in a symetric version. (just an idea)<br><br>Guides for parallel movement.(Rods)<br>Releaseknob on top.<br><br><img src="http://up.picr.de/12423890ve.jpg" border="0" alt=""><br><br>Zwillie

    <span class="postbody"><br><br>it makes not much difference that one arm is a little bit heavier. draw weight of the bands and ammo (bowstring/arrow) are much heavier. the release is hanging on a cord, not mounted to an fixed objekt. also it's spring assisted to open quicker. there will not be a pushing action, it just releases. you're touching the trigger only on the side where you're pushing it, so you won't really influence the arm thats attached to it.<br><br>that sketch is just a possibility how a bow release works. as i said, its a simpler version of the real one that has rollers, adjusting screws and not the little spring on the bottom. i added the little spring to prevent self opening - not really necessary and thinking twice also no good idea because the movement of the trigger would be handicapped.<br><br>sorry to say that, but on your sketch, synchronous opening is also not guaranteed. you won't be able to make it that precisely that both arms open at the same time and you have to pull the trigger very fast (springs are working against it). otherwise its not really an issue like much simpler trigger mechanisms on sling-x-bows proofed.</span>
