    The Oreo pump gun is just too good to be used for just one project.

    Therefore I decided to make some cookies... from steel!

    A large M14 washer has almost the exact same diameter as an Oreo.

    But it is much thinner, of course! So I decided to glue three of them together, with super glue.

    Oreo = 11 grams

    Three large washers = 104 grams!

    I also made some with two smaller washers at the side.

    [​IMG]

    The lighter version weighs 46 grams, the heavier type 64 grams.

    And of course I had to "devilize" one... razor sharp edges. 37 grams!

    Of course I had to increase the rubber on the weapon. In fact, I now use five times as much! That's right, 20 cm of TBG on each side. A mighty brutal shooter with fearsome momentum.

    Video on the morrow!

    NICE!!! I like the beveled one. Like a deadly, mini UFO!!!! Definitely don't want a hand strike with that!!!! Interested to see what the flight dynamics are. Any way you can shoot with the slo-mo camera from a "shooters eye view" or just over the shoulder. Be cool to watch this and various other ammo fly from this perspective to get a look at if it curves, wobbles or tumbles. Could be very informative regarding ammo selection. Possibly clamping the SS in a vice on a stand so it's in the same position, allowing room for the camera to be set up as directly as possible behind the line of shot.
    More coffee shop engineering thoughts.........:D;)

    Suggestions for ammo for testing:
    Your oreo washers
    Various size nuts
    steel ball
    lead
    smooth and rough stones
    glass marbles
    round rod stubs
    threaded rod stubs
    1/2" steel square bar cubes
    aluminum balls
    tightly packed tinfoil balls
    chickpeas
    paint balls
    clay balls
    oreo's
    gum balls
    Various homemade arrow/bolts
    .........?

    Looks cool!

    Wouldn't the razorsharp edge damage the string that pushes the projectile?

    It really would be a waste of great engeneering and cookies. Looks lie a better ammo.

    In fact I had to blunt the edge a bit so the string would survive. It is still very sharp, but no longer scalpel sharp.

    I originally planned to exchange the string with a steel cable, but the clamps you have to use to make a loop for the rubber bands are way too heavy, smashing the wooden sled to pieces.

    Cant wait to see the Steel Ammo fly :D
    Maybe you can take the Shoot Mechanism from my Slinggun for scalpel sharpend Ammo.
    The Metall one is to heavy so i change to a plastic one.

    There is a material that might work quite well in abrasion-prone applications. Steel fishing leader material. Most often, it is made of several hair sized strands of stainless that are woven together and then coated in a flexible clear plastic (you can also find it without the plastic). It is available with many different breaking strengths, and for relatively cheap too. It offers a great compromise, being lighter, and thinner in diameter than any cable, but very, very tough.
    You may have already looked at this stuff before, but I figured I would mention it.

    Oh you had some camera trouble? Was that a different camera than the usual?

    Here is the video:

    I am testing a new tablet based editing system, which is still in alpha development. There is an issue with the codec, hence the funny interlaced effects.

    Jörg, the first time I watched, you were with this very weapon. A friend of mine shared the oreo shooter on facebook.
    The result..... I started making slingshots (I had a great background on slingshots on my childhood) again!
    Another result: I don't acess my facebook more than once in a week. And acess the slingshot forum ten times in a day!

    The greatest things in this video: your laughs. Your wife's laughs. And your fat cat wandering everywhere!
