I wouldn't push it c_aardvark.  

Matthias said he'd offer help.  So why don't we give it a shot and make our own.  I am sure it would be more cherished that way.

Matthias,

Where do you get those lead core stuff?

Tint,

Lead core fishing line should be available anywhere you can find fishing supplies.  It is exactly what it sounds like: fishing line consisting of a thin lead wire, wrapped with some sort of fiber braid.  It is commonly available in the U.S., even in California where products containing lead are frowned upon and lead shot (for duck hunting) is no longer allowed (spent lead shot gets scooped up when waterfowl are gathering gravel for their gizzards, and the lead kills them).

Nobody tried this yet huh? I thought for sure that slingers everywhere would be scampering off to their local tackle shops... Undecided

As for me, I'm not sure that I'm ever going to be able to use a regular sling again, except maybe for missions requiring extreme stealth. Gen II is coming soon...

No doubt,  it is impressive.....I am sure my son will want to try it sooner or later.

I am sure that acceptably accurate ammo velocity measurements may be obtained by slinging at an accoustically accomodating target at a known distance and measuring the amount of time between the sling's report and the impact report.  Plugging in the known speed of sound at your altitude and the difference in time for reports to reach the ears of the measurer as well as a reasonable assessment of the time differential of the ammo dump and time of sling report.....yada yada....of course, one may simply use a normal sling and start the stopwatch at the moment of release and stop it upon hearing the impact and calculating from there as well.

Knowing Caleb, he will use a signal sling to bamboozle the neighbor kids into thinking he can sling a rock at supersonic speeds!

I don't doubt as well that you, Matthias, may find a way to actually foment such an actual eventuality!  Hmmmm...



Peace,


TS

Matthias,

I like the whip effect very much. Some time ago I used slings with leather strings, they crack very nicely and loud, but it can't be compared with yor whip-sling. I'm sure that the stiffnes and proper elascity of the cords are significant factors, either.

It would be great thing to get an idea, how to accelerate missiles by the whip ending, in a good direction. As TechStuf said - a supersonic sling  Shocked

In the shape, structure and position of each stone, there is recorded a small piece of history. So, slinging them, we add a bit of our history to them.

I think the crack gives a better more precise release to the throw.

Supersonic throws would require a very clever design.......we are shooting at less than 1/3 of the speed of sound at the moment.  Even crossbows darts are going at less than half the speed of sound.

Talking about stealth and supersonic, did anyone see the movie "Stealth"?  I really enjoyed it.

Good points Funslinger......I am sure that.....say, a 50yrd shot could provide meaningful data without necessitation for factoring any kind of ballistic
parabola.  Possibly more using the overhand cast with a backspin release and the right ammo....

Hello Matthias,

I really like this piece of art, amazing!
Do you think i could have good result with something else than lead core string? I went to a local fishing shop this morning, and was a litte disapointed: this king of fishing line is very expensive (10 Euros for 10 meters), and they have only one color (dark green).
And could you give some informations about the total lenght of string needed for such a sling? I am not a specialist in braiding, but i really want to try this, even it take me months.

Thanks

Joseph

Hi Joseph,

That's about 10x more expensive than I remember mine being. They do make leadline in different weights (I have some that weighs 3kg/m!) so that might have been part of the problem.

The pictured sling has ~30m of line in it (the colour on mine changes every 10m and I used three colours + a little). You can work it out from the braid as well - 24 strands tapering to 0 over about 1.5m = 36m / 2 = 18m + the allowance for braiding. The braiding is actually much easier than it looks. I f you can handle a "standard" four-strand round braid, you can figure this one out - just need to keep the strands under control!

I've been trying to come up with something that would be easier to reproduce. The trick with the weight is that it needs to be heavy, and taper smoothly from the grip to the release end. Braiding in the mass works well, but is certainly not the only option. Leather whips are often made with a sewn conical bag that is loaded with lead flour of shot, for instance, and copper wire or similar would probably be ok as well. If you can track down any whip-making resources you'd be ahead of the game.

My sling doesn't seem to be cracking as loudly as it used to, and I don't know enough about whips to diagnose it. I think probably the cracker is getting too "fluffy" and soft (easily remedied), and the braid seems to be softening up a bit as well. I'd like the next one will be heavier and a bit longer.

I think a better approach might be to try to make a tapered solid core (split at the pouch) and then tightly braid a cover using tapered leather strips or synthetic twine. Maybe bind the core with cloth surgical/athletic tape first? I'm not certain - but the more people experimenting the more likely we'll come up with something good!

Is the video of your "signal sling" available anywhere else?  When I click on the link you supplied it says that it was removed and is no longer available.  Angry

I'd really like to see and hear this puppy.
Thanks
