Also nichts für ungut, aber man hat dann bestenfalls verstandern, dass solche "Faxen" für die Reichweite überhaupt gar nichts bringen.

Das Ziel eines guten Schleuderers ist entweder die größtmögliche Wurfweite oder die bestmögliche Genauigkeit / Trefferquote oder beides bestmöglich kombiniert, aber eben nicht die bestmögliche Bedienung der längstmöglichen Spaß-schleuder.


In english:

Jaegor: "If you have learned to grap (a very long) sling first shortened and to throw its full length (potential) only when change into the last round (for release), than you have understood."  - end of message -

Me: So nothing for non-sense, but than you understood at the most, that those "jokes" effect nothing for higher ranges.

The goal for a good slinger either is the highest range or the highest accuracy or both in most perfect combination, but not the best handling of the worlds longest "joke-sling".

Yes - most of the shown styles are the same as my own styles (side-arm & helicopter).

No - I already wrote (in german / my first post for Jeagor): "Principel nothing is to objekt against "pirouettes" , but it wents for bad results (low ranges & lowest accuracy). Pirouettes are only good for increasing the weight of bullets (have a look for hammer throwers) and the length of a sling."

What should be the sense of using the most possible long sling??? Is slinging an "(martial) art" or a joke for "burning down the daylight" (ment: "... for wasting time")?

Maybe I misunderstood the topic as "the highest length of a sling which almost is full of sense / effect" (*) 

But I've seen you to confirm in the mentioned paradoxon: "master(class) of stupidity" like: "masterclass in how to handle a stupidly long sling". That means of course: "This length is not "a sling or slinging" but non-sense."

* Topic / Editorial: "the point of this (the absolute maximum length you can make a sling ...) is obviously to get as much range as i can with this." 

The caulk tube bucket sling has given me around 900 ft with golf balls and it is 44 inches long

pirouette is used by few members and it seems to have potential .

in pirouette you are not making only circles with the sling but before release the throwing arm moves forward making sling trajectory ellipsoid
also pulling the non-throwing arm to the body increases rotations/second


the leverage of a pirouette style is probably greater than that of other more linear throws..

pirouette surely has issues with accuracy and seems more skill/coordination demanding than other styles

1,4m sling + 0,7-0,9m(center of chest to fingers or half the height of a man)=2,1m-2,3m

circumference of circle =2*pi*radius=13,2m-14,45m

for 65m/s you need 4,9-4,5 rotations /second
and you need that only at the moment of release not during the whole throwing motion....
i think athletes reach such rotational speeds with a discus in the hand which is heavier than a sling and stone

@Parmenion: " ... for 65m/s you need 4,9-4,5 rotations /secondand you need that only at the moment of release not during the whole throwing motion....i think athletes reach such rotational speeds with a discus ..."


No chance - right this is the point: With an by a long sling elongated arm you are not able to make only 4 rounds per second. And while throwing a discus you have your arms not elongated, because nothing longer than only your streched arm (and a discus).

I said, the longer your "arming" (wappon) is the longer becomes the sequence (! not frequence !) of its turning.

Maybe a very tough "Princess on ice" is able to make 5 or 6 turns per second, but those keeps her arms (and legs!) very close to her body and first must have done a very complex / difficult "introduction" / "start" for this moving. But this princess hasn't any "arming" to accelarate with her.

Give her a long sling or rod (each 1,4 m) to hold "streched" far away from her body axis, and she does nothing comparable anymore ... or just maximum 2 rpm.



In the last 30 seconds of his video David McNamara shows you what only "3 rpm" means:   https://www.youtube.com/watch?v=sK3H45Qld3k

And right this (orbital speed of bullet) you never never never will reach or imitate with pirouettes! Also the amount of "extension" (for a change into an elliptical trajektor) is nearly "nothing" when making pirouettes, because the relation between small and large axis (of the ellipse) stays nearly 1 : 1, while this could be up to 1 : 3 (!) when throwing by "helicopter-to-sidearm style".



The following vid shows very clear and impressive the length of "extension" when the slinging hand is tracked from behind the body into the front of body:   https://www.youtube.com/watch?v=rzUAdkoAfbo

Only this can explain / declare the high difference between calculated orbital speed and real orbital speed. The real speed is more then twice as high as the speed which allways is calculated from the bloody stupid combination in "circle, radius & frequence". In the last moment of slingig the trajector isn't a circle, but an ellipse, and therfore you must not calculate like "Thales" or "Galilei" but calculate like "Kepler" and his third or second law.

And please ... think twice! ... Even timpas fastest pirouette comes up with maximum 1,5 rpm. One second is done within only a second! "Zack" and over! What the hell do you think can be done in only one second?


Is your breakfast done within "15 seconds" too???


Timpa makes ONE full turn / round (and a half) and one second is OVER! While tracking his slinging hand to the front of body (at the same time) that sums up to maximum 1,5 or 2,0 rpm. And while this is done by him I can't see any transmission or change from a circle into an elliptical trajektor. But to speed up a circular round isn't the same as its extension / deformation to an ellipse, because "to speed up in a round" is only an addition, while from its extension results a "qoutient", respectivly a multiplication.

If the remarked "extension" change the circle into an ellipse with axis-relation of 1 : 2 than the orbital speed of circular trajektor becomes twice. If the extension change the circle into an ellipse with axis-relation of 1 : 3 than the orbital speed becomes the "triple" (don't know if this english word is the right one in this case of "syntax" - meant is: "a three times higher speed").

I will try to imagine this "secret of a slings high momentum" with help of a drawing until tomorrow - perhaps until the day after tomorrow (= sunday). At the moment this draw is still in work and only a "vector" in corel draw format (.cdr) - so I have it first to bring to an end and to convert into .jpg or .png which measures fits here on it's best.

Ich hab pirouette Stile versucht. Sie sind umständlich und bringen effektiv gesehen nichts. Auch wird immer wieder etwas vergessen. Das schnelle drehen einer Schleuder bringt sehr wenig . Dadurch wird nicht die Power einer Schleuder bestimmt. Ich erklärte es schon einmal. Es ist ähnlich wie im Karate. Der letzte kick aus der                                                                                     Hüfte bestimmt Power und Geschwindigkeit. Nicht der Arm.
Das gezeigte Video von Apex hat daher einen kleinen Fehler. Nicht der Arm geht zuerst in eine Vorwärtsbewegung. Die Hüfte kommt vorher. Sie nimmt denn Arm mit nach vorne . So erreicht man sehr hohe geschwindigkeiten . Kommt die Power nur aus dem Arm, wird dieser ihnen mit der Zeit Schmerzen bereiten. Es gibt sehr viele Slinger die daran leiden. Ihre Technik ist einfach nicht richtig.
Sehen sie Lui an. Zuerst kommt die Hüfte, dann der Arm. Er trifft. Mit großer Kraft. Manchmal jedoch gelingt es ihm nicht. Zuerst der Arm und dann die HÜfte. Seine Treffer werden sehr viel weniger. Ich bemerkte dies auch bei mir. Auch bei anderen. Gerne würde ich es ihnen zeigen. Sie würden es sofort verstehen.

Now too much attention is paid to rotation. The pirouette gives only a good start.
Notes: Hand performs a throw.
