Not a weapon really, just a crazy contraption.
Totall madness I like it
So this uses a rubber torsion arrangement... good thinking! Love it
Fun idea. I'm still having a hard time picturing exactly how the spike is launched though. Do you have a video that shows the operation of the device, say from the side? Does the spike go inside the tube and just get flung out as you shoot it? Looks like a fun toy to have around.
Appears to work much like a clay pigeon thrower does. When he releases the trigger the rubber pulls the arm around 180 degree's flinging the spike out the end of the pipe near the end.
Nice thing about this is that it is scalable, longer arm, more rubber = more speed and energy. With a longer barrel for round balls I suspect it could be quite accurate.
Nice little machine.
ill say,... scale it up
I kind of suspected that by looking at the design itself. I'd still love to see a side-on video of it firing though. I'm surprised that the bolt is as accurate as it is using this mechanism.
I don't Know what's more dangerous the contraption or the hat. I love them both.
Hey there MountainStorm - nice contraption
How much does it kick back when you fire? as the weight being moved is away from the pivot (it has to be, else you'd get no centripetal force on the projectile) does it push down on the back end? I'm sure you've guessed that if you use a smooth steel rod instead of threaded you should reduce friction. I like it a lot because it is a close model of how a bo shuriken can be thrown
