Pump Action Slingshot!

Postby JoergS » Mon Oct 10, 2011 3:27 am

A true repeating slingshot crossbow was always something I knew I had to make one day. Lots of problems to be solved. How do you deal with the band twisting? How do you cleanly line up the "pouch" every time? How do you feed a ball into the pouch without jamming?

Now I have done it - the first functional repeating slingshot crossbow is reality. It "fires" 20 mm (.79") steel balls.

The weapon can be loaded with 20 "rounds" within just a few seconds. Then, a simple racking action feeds a round into the chamber and cocks the bands.

The weapon is used here to smash eight glass bottles, which is done in one uncut passage with just six shots:

Can I get one with a rail, please?
Seriously, though, pure awesomeness. Will shoot rocks, or anything of the like found in the PAW?

Talk about an AWESOME video! Very high production quality on that intro, to say nothing of your latest awesome wood-and-rubber homemade death machine! It's like a SlingShotgun! :D Just need to figure out how to make it fire lots of little round shot too.

A new level of awesome has just been reached, one that has never been seen before in the likes of such mortal men as us.

Is there any way that this design would work in a bullpup configuration ?

My thinking is probably not without getting whacked in the face by the bands.

Though if anyone can figure out how to make something without getting whacked in the face, it's JoergS.

My God, JoergS! Watch enough of your videos and as a body of work they develop a kind of critical mass of destructive genius. I simply am incapable of watching one now without a huge smile spreading across my face.

By rights there is no way one man could possibly sustain an entire Youtube video channel devoted exclusively to slingshots. But just when I think I've seen everything, that demented mind of yours comes up with with something new, and your prodigious engineering skills transform it into reality.

I'm not sure whether you are a mad scientist, a naughty school boy or some combination of the two, but whoever you are, I hope that magical streak of creative mayhem never runs dry.

Thank you for bringing so much maniacal joy and destruction into this buttoned down, overly ordered world. Bravo, sir. Bravo!
