With the completion of the artwork and attachment of the armor, “Devas-tater” is finally finished. See the complete build at my blog starting here .

Here’s a video of loading and shooting. Sorry about the plumber’s butt; I do need to drop some weight. By the time this was shot, we’d fired several rounds, and I was getting pretty quick with the loading procedure. You can see me pounding the projectile onto the cutting edge of the muzzle. I say, “Stand by….fire”. It’s hard to see the trigger wire with the low resolution, but the trigger operator is off camera to the right. It’s quite a bit louder in person than on the video; loud enough that I have to cover my ear on the near side.

Fire mission, Battery one round. Wow Awesome job, I was a Artillery man when i first joined the Army. We stayed out in the field 250days out of a year fireing howitzers. It was fun; However it was, cold, rainy, muddy and snowing most of the time. It was a hard job. I love your version. Superb work.

definitely the most badass potato gun i’ve ever seen!! my dad is a plumber – so when i discovered what a potato gun was years ago, i raped and pillaged his PVC stock, and made a 6’ long one – that thing shot SO far – and of course used an old grill lighter as the igniter – I also sharpened the end of the barrel so the potato got cut on the way in, and fit it perfect. Great potato gun! haha – thanks for posting

With the right barrel insert you could make some scattershot french fries.

that’s the best model tatergun I’ve seen…really cool. I’ve made some hand held ones 20 years ago and with the right barrel a D cell battery makes a good projectile, shoots straight and lethal at 100 yards, superballs work great in them too.

I was not an artillery man, but I’d own a tank if I could! Those 5 of you (so far) that have this favorited – I expect to see your version in the spring!
