Ich verstehe nicht was das soll? Das Video soll was beweisen?
Es ist nicht gut das Video.

it doesn't mean anything in particular. It's an experiment I wanted to share with people.

I also have one idea about this sling. I'm trying it out this summer.

Was für eine Idee? Was für ein Experiment. Wo soll das Experiment hinführen?

@Sarosh - Well done.  That thing is definitely a piece of work.  I'm interested in seeing your development with it.

Does it feel as though your getting a more powerful throw than with a normal sling?  Or potentially could?

@
timpa
can't wait for your idea

@
joe_meadmaker

can't really tell. the trick would be to feel just normal but produce high speeds. heavy slow movements to produce a fast cast.

I didn't throw for range... so i can judge the power only from the hits on the wall and the cliff, and they sound normal, what would be a 45-50m/s throw.

in the video is every throw I've done till today . It potentially could be better, a longer sling with better tuned release angle. and a better booster mass:projectile mass ratio.

what i've learned is that the sliding mass is better than the fixed and that the 500g are better than the 1kg for 30-150g ammo.

oh i should have put this in the video Tongue I'll put it in the description

that's a pretty good start Thumbs Up

Just need to be able to use it without getting dizzy and falling over Smiley

The original idea is to hold the missile and swing with the larger weight.
This builds up more energy than you can put into swinging a small weight.

My original plan was to use it for slinging paintballs.
They work great from a catapult, just too light fora sling. Although using a weighted pouch can help.

Probably best to use with a shorter sling though, both for practicality and simplicity Smiley

This is looking really promising. A tuned up version could have a really powerful throw.

if it was made for paintballs then a lighter booster mass would be suitable 50-200g like normal ammo mass, at that mass a shorter sling would be better than a pirouette length sling.  I don't think weighted pouch would be needed for the paintballs.

practicality and simplicity are already compromised Tongue

pirouette allows me to safely and efficiently use 500g-1000g booster mass and throw ammo of the same mass as with the simple sling .

next level would be using hammer throw style, 5-10kg booster and holding the projectile with the teeth  Grin

you use a weighted pouch for slinging paintballs with a standard design sling Smiley

Tryig to sling a really light weight, causes joint and muscle issues. It's like throwing a punch and missing.

It's what got me thinking about the compound sling in the first place Smiley
While ago now - probably still got the paintballs too !

It may not be of any use. But it's an interesting experiment

@Sarosh: that’s a very nice start! please post the drawing and some photos on here too so we don’t have to pause the video to get a good look at the sling.

@Jaegoor:  The purpose is clearly stated... the goal of a compound sling is to achieve higher velocities with smaller projectiles, but this comes at the cost of increased complexity. Sarosh is demonstrating a proof of concept, not an optimized system. If you see no purpose, it’s probably because you lack the imagination to see past the flaws of an early prototype.
