Starship without butt

A "Starship" is the slingshot term for a forwards extended slingshot. As the wrist strain would be enormously high without a wrist brace, starships always have such a brace, and look a bit like the Enterprise NCC 1701 - hence the name.

Gary ("Flatband") recently started to play with full butterfly starship shooting, a new style he calls "Superfly". Now I have to try that too! Unfortunately arm braces are illegal in Germany.

So I used and older design of mine (the "Gloveshot"), because that concept avoids unwanted turning of the slingshot in the hand. Much needed for these not undangerous experiments! I simply sawed off the original "fork arms" and attached a 50 cm draw extension (20").

It works! Takes practice, and even weak bands are kind of hard on the muscles in my forarm. But hey, everything for power!

  1. nice alternative solution for germany, but it looks a bit uncomfortable.

    perhaps an "anatomic glove" model to slip in would be better to hold the ship in the right direction with the strenght of each phalanx.

  3. it should be really hard to draw this way

  4. What do you mean arm braces are illegal in Germany?

  6. cool video. I'm very surprised that the marbles go in deeper. And I seriously doubt that it has to do with the surface. Then it has to do with the velocity of the projectile. Tough stones and marbles have the same energy, the marbles are therefore a little faster, since they are lighter.

    It has to do with the way the projectile interacts with the gel...
    Hmmm strange...

    Could you maybe film (highspeed) a a steel/marble/stone ball shot into water, and see how far it goes? Gun bullets are stopped pretty fast: http://www.youtube.com/watch?v=0WIIKje1g2s&feature=related

    That would be very interesting!

  7. Well this looks very interesting, how much time did you need to complete this slingshot?

  8. Looks like fun. Maybe a good platform for another side x side arrangment. I really like the side x side.

  9. The rope idea is an answer, but this sling-shot is not up to what we have come to expect from you. It has none of the beauty nor the practicality, nor the 'fun' of your previous work. Don't mean to be over-critical, but for the first time, I don't like what you've created. Sorry, but there it is.

  10. Tosh Togo, this is very much an experimental frame. I had no idea if it would work. Put this together in an hour, no time for beauty.

  11. I take it the issue here is with the slingshot pulling "up" when you draw the bands back. Would a rope from the front edge to an anchor point on the ground or your foot decrease the strain on your wrist? Not an elegant or convenient solution, but it might work!

  12. CaseFace, I did exactly that (rope to the foot), and it works really well.
