Ultra heavy sling
Jul 31st, 2017 at 5:05am
 
After spending a week in Scotland and getting acquainted with it's lovely beaches (and GREAT slinging rocks) I started pondering on a new sling project.

Some of you might recall my first sling (simple basket paracord sling, throws rocks up to egg size) and my fugly sling (throws anything from tennis ball to half brick). Besides the great training I got (having round, smooth rocks really improved my accuracy, even allowed me to see where I needed to progress the most, eg late release for overhand when aiming at low targets) It got me thinking about the following:

"What if I could transform into a (small) human trebuchet?"

Let me explain: when I gave my fugly sling a try I almost seriously crappity smacked up both my elbow and my shoulder. To get a nice 45° trajectory without inflicting crippling torque on my arm I had to do full arm underhand swings. Still there were even bigger rocks around and it was obvious that I'd need an even bigger pouch and an even greater sling length if I wanted to throw them at any significative speed.

I decided to put on my to do list the following sling manufacture task:
- split pouch, from brick to double brick sized amo
- sling length: at least a meter

But then I wondered, HOW am I going to use that monster?
So here I am, does anyone here have any experience/historical data regarding ultra heavy slings for this kind of ammo?

I thought about using it by spinning on myself (starting with most of the sling cord in my hand and releasing more as I gain speed) but I'm not sure it's the best way.

Can it be done? How?

Regards,

split pouch and large irregularly shaped rocks = serious accident waiting to happen !

you could try pirouette https://www.youtube.com/watch?v=4HzzudOV7D0

but slinging heavy and big things is probably gonna take the fun out of it , too much time reloading and huge tiring  movements...

Es gibt balearische Schleudere die werfen 500 bis 700 g . Das halte ich für eine Obergrenze. Selbst für eine Staffsling . Mehr Gewicht ist einfach Unsinn.  Verwenden sie einen Onaker oder eine Mann Blide.

You ment me? "Achap" like "a chap" or "one chap" Huh

No, sorry - I said to hold me "in the near of Jaegors posts (or threads)" perhaps to get some friendly HELP for translation of my german speech into english from Jaegor (if I ever should slide in such needs).

But "okay" - I turn that stick and try a translation. Jeagor wrote:

There were seen balearic slingers, used (? "able" ?) to throw stones with weights about 500 g up to 700 g. I keep this for the top of a limit (ment: "more isn't possible at free moved hands / arms by one single man) - even by using a staffsling. To handle higher masses / weights is simply non-sense. Take (instead of this / better) an Onaker or a "Mann Blide" (? wtf ?).

- end of message -

Sorry - I for myself never heard or read "Mann Blide" before.

But in the meanwhile i was looking for help by wikipedia (german version / article) and found there following informations (translated again into english by myself):

"Mann Blide" is a special form / type of "catapult" which is loaded up with "men" (but not to throwing men, of course, but to load up with "sling-power" or weight that consists in a small number of men ... to be able to "enforce & re-enforce" it in a very small time). Alternative names: "Tribock" or Tribok (Plural Triboke), also "Trebuchet" (frz. trébuchet, lat.: trabatium). Therefore up to 15 men jump into a free swinging "chest" or "cabine" to give that type of catapult its power to accelerate a single bullet very strong.

The simpel word "Blide" (from greece: "palida") instead means nothing else but "catapult". Palida or Blide may be related with the english verb "be-load" (compare the english noun: "lead" and "blood" or german "Last" / "Ladung" and "Blut" / "Blüte") and german: "Be-laden" likely "be-leidigen" (= offend - to throw "dirt" at somebody) or "be-lasten" (also related to eng.: "bless" = nhd.: "be-lassen").

(Wiki wrote: "gr.: palida = schleudern" or "gr.: palida = slinging", but etymological are those claims very "in-logical": That an "A" means "B" is simply absolutly impossible).

"Onaker" (also: "Onager") is that type of catapult which is enforced by winding up a bundle of ropes to move a large kind of "spun" very ruptly (explosively).

Now i hope these words sounds nearly "readable" in english ears too.  Lips Sealed .

Thanks for the amazing videos... It made me reconsider and think about making a good ol' fustibalus. I'd love to try and shoot it almost veritically down (such as in machiculations or just past crenelations).

I'm starting to understand why metal or clay ammunition was favored when available. Finding the perfect rock is hard and if you can just make hundreds of perfect ammunition befhorehand it does make your life a lot easier...

Still the influence of quality ammo does baffles me. It was way easier to time my release correctly with smooth, regular stones than with the usual crap I throw... It got me thinking about making precise mesurements.

Has anyone thrown an apparatus containing a gyroscope (such as an MPU6050 linked to an ESP8266 that wrote to an SD card/sent data via bluetooth while flying) using different projectile shapes?

Well, keep in mind that it was just a random thought so it might be completely and utterly stupid.

I was thinking about measuring the acceleration during the whole throw while streaming the data or putting it someplace safe-ish since it's probable the whole apparatus will be destroyed on impact.

One could also measure the tumble of the projectile during flight.

If you create a small enough apparatus you could easily enough add some weight and put everything in a container with the right shape. A bit of hot glue to keep everything together and you have a way to test different shapes.

I can make the case for you - no problem.
If made from a flexible plastic or rubber filament - it would also survive impact easily and help cushion the bits inside.
Drop me a line and we can discuss it Smiley

Something to measure actual rpm of a slung missile would be very cool. 

Was going to make something similiar with a bbc microbit to test pouch speed. But david morningstar didn't write me a script.
Keeps saying how easy and quick it would be to write - but actual results, nada.

Man powered trebuchets !
never thought of that. great idea !

If you agree with the  thought. That the first sling was just a rock tied to a string then the first ultra heavy sling is the Olympic hammer throw
