Almost 132 joules with a slingshot XD this is totally cool ; now you know what's the next thing to do : upload vids!!!!!

Here is the video, guys.

Enjoy!

Looks like quite a workout, your grin at the end is quite justified congratulations. Now for some damage shots though

Yeees.... Destruction!!!!

Can't wait.

Here is the impact video.

the link dosent work

damn nice vid man!

Try again, I misclicked.

nice videos... but either some of the shots were weaker than the rest or LCDs are really tough...probably it's the latter as I can see as energy was being transferred to the backstop

you're Heinz Guderian of slinghshots no offence intended you're just that good

Plastic IS tough, man.

Guderian? I am no nazi, those cruel, stupid, crazy, sick guys set the world aflame. But I can see that you meant that as a compliment, and I truly appreciate that.

My tests show that a slingshot has limits. No comparison to a powerful firearm. But fun!

And legal.

...No comparison to a powerful firearm. ...

With heavy, longer ammo, say arrows they come close at close range probably.
Also, underwater, latex/ similar bands will propel a projectile further than a firearm, much more effectively too...(edit: normal firearm/ammo)

Heck, the for the amount of time and money going into some spud projects probably atleast two or three of these could be built and registered legally...
(just check the sling pic w/75 rd. drum mag... )
But that's not what it's about ...

Alternatives, areas for experimentation, discovery of benefits and advantages for different applications...etc.,etc.

Cool vid Jeorg!!!
(the cat part was funny too, nice music as well).

uhmm sorry I shouldn't put it that way... that was pure PUI

do you live in Germany ?? I am asking because gun laws in Germany seem to be as restrictive as in Poland...

are you into pneumatic spudguns ??
IIRC german law is similar to polish in that respect... so there is a limit on muzzle energy (17J in poland)...


Doesn't the device that you use one this gun count as a trigger mechanism??

It's a function of the relatively low velocity of the projectile. The energy is certainly there but since it's travelling so slowly, the target has time to deform and absorb the impact without penetration.

Good stuff Joerg, you set out to push the envelope and succeeded

Yes, I live in Germany. No, I am not into spudguns. The limit for these is 7,5 Joules here (a joke) and even if you keep that limit you need a license to make them, they qualify as guns.

The release does not qualify as a trigger mechanism. The law says that it must release "stored energy" and then the projectile must go through a barrel. So crossbows are OK. Spuds aren't.

So technically, if you made a pneumatic that used a piston to strike a projectile, in the same way that a nailgun drives nails without them coming to contact with the air, it would be legal?

A bit like the way the (ironically also called "crossbow") Armbrust anti-tank launcher works
