    Lightbulb World's first Big Game SlingBow 216 fps

    http://www.youtube.com/watch?v=186aqlbxNlI

    My homemade world's first Really(!!!) Big Game SlingBow.
    Draw weight 44#, arrow 8 gpp (grains per pound), blistering speed 206 fps, Kinetic Energy 33 ft.lbs.
    (Easton Kinetic Energy Recommendation Chart: deer hunting 25-41 ft. lbs).
    http://inberg.ca/ballistic_calculator.htm
    Other my competitors slingbows achieve maximum speed 161 fps and 20 ft.lbs of KE.



    Only the best traditional hunting recurve bows can shooting a little faster like my SlingBow... This is world's smallest Really Big Game archery hunting stuff too. I showed just a homemade prototype built provisionally; but made later by a professional manufacturer should have such performances: draw weight 60+ pounds, arrow 420 grains 235+ fps and KE 51+ ft.lbs.
    My SlingBow is hidden, because my idea is not patented yet.

    I recorded speed a light arrow 6,6 gpp, without fieldpoint too: 216 fps:

    When I was a kid I mounted a lizard tongue rest blade on a wrist rocket sling shot and used it to launch arrows. At close range it was a blast.

    Because it is not already patented.
    Look at your archery equipment: limbs, cams, rest, nocks and others: everything patent pending. Even the little things.
    But my SlingBow is not a little thing, this is a revolutionary project: world's smallest, pocket size deer hunting stuff. Cheap (two rubber tubes only 2$), and fast like good quality traditional hunting bow, compare:

    Yes, it is small and not very costly, but what is its accuracy at 20-30 yards?

    There is already a slingshot out that will pull up to 70lbs and shoot over 200 fps. According to their claims anyway.

    Sorry, but this speed is a big lie. This construction is much slower, look this thread, #8:

    Don't understand why you didn't show the sling bow. If I recall where're you tube videos on who to make it.

    I have a hunting buddy who was talking about doing this last year, I get the idea but don't see how it would be better than a vertical bow. Fun idea, sure!

    How different is it from this? Thinking about playing around with one, looks like fun.

    there was something like that years ago for sale in the back of soldier of fortune magazine.. wrist rocket, used tubes(metal) and wheels, to increase lbs on the band, and used a short bolt - not sure if you could use a broadhead though.. wish i had one now, was cool..

    Experimented for many years with slingbows building. Of course the first design was the same as another slingbows: simply fork and strong rubber tubes or bands. This solutions is slow because strong rubber is heavy; during the shot must not only propel the arrow, but the rubber too, which is heavier than the arrow. Most of the draw energy is lost.

    When you increase the weight of the arrow - more energy is transffered to the arrow, but unfortunately this arrow is more slower.
    I got most of the Kinetic Energy (24 ft.lbs) when the weight of the arrow was 640 grains (very heavy), draw weight was strong (over 60 pounds).... but arrow speed was only about 130 ft.lbs.

    24 ft.lbs... 130 fps... this is not ethical deer hunting. Hunting is very difficult (almost impossible), because deer jump hearing shot. Arrow flies very slowly, the deer has time to react. And arrow penetration level is small.

    Because my final solution is other:
    1. Thin - so light - rubber tubes
    2. Complicated mechanism suitable light arrow (350 grains) high speed (206 fps) and much more - 33 ft.lbs of Kinetic Energy, enough for ethical deer hunting.

    Cool idea. This may be a glimpse into the future of the USA if the liberal mafia ever takes our weapons away from us. ( And don't fool your self, they are trying to EVERY DAY.

    jopsa, finally got to watch your video on youtube what I heard seemed ok, but I've built a couple slingshots in the past which were very much like the older wrist rockets, but much beefier, I used tapered speargun rubbers on the last one it was extremely powerful and would propel a 2 ounce lead sinker over a quarter of a mile accurately and still have the power the go completely through a metal garage door, now I have no Idea what that would do with an arrow, but I'll bet it would be awesome.......might check into the speargun stuff.....

    "Like traditional bows" does not mean "easy like traditional", but "difficult like traditional". Requires a lot of training - like traditional bow.
    I can not show the accuracy, because I am RH, but my right dominant eye is completely blind now (accident - the retina abruption). I can not shoot more, I can only design.
