The Spud Gun To End All Spud Guns

In Norse mythology, Mjöllnir is the hammer of Thor, forged in a contest to create the most wondrous and munificent tool for the gods of Asgard. While we’re not aware if [MrCrowley] recently made a bet with Loki, his version of Mjöllnir, a gigantic spud gun powered by MAPP gas, is wondrous enough for our tastes.

Unlike most of the other spud guns we’ve seen, [MrCrowley] eschewed the use of PVC pipe and fittings in his build because that would explode on the first test fire. Instead, the gun uses galvanized and stainless steel for the majority of the construction. That’s not to say this spud gun is necessarily safe, though: as he demonstrates in the video after the break, golf balls exit the barrel with a comparable energy to most rifle rounds.

For an interesting take on an ignition system, [MrCrowley] built a remote ignition system out of a wireless doorbell and a 100kV stun gun. While this does allow for remote firing, the entire build seems safe enough – from behind the muzzle, at least – to be carried with a rifle strap.

It should go without saying that this is incredibly dangerous and you shouldn’t build this if you’re not planning on your last words being, “Wanna see something cool? Hold my beer.” That being said, [MrCrowley] knows what he’s doing, and you can check out the video of Mjöllnir in action after the break.
