My home made air gun
I was messing around at my friend's shop and made this air gun. It was originally going to launch tennis balls for the neighborhood dogs, but my dog didn't like it. A neighbor was looking for a gift for her husband and asked if I'd make one for their desert trips and make it to launch potatoes. I said I'd do it and I knew I couldn't just give them a pipe with a tank and valve.
So, after about 5-6 weeks, this is the result. The tank is a propane torch cylinder that typically has in excess of 200 psi in it and I believe is capable of over 300 psi (I have enough of them i may hydrostat one to destruction). The valve is a Irritrol sprinkler valve rated to 150 psi, the trigger is a simple air bleed button. The grip is a $5 AR-15 part, the barrel is 2" x .065" aluminum, the shroud is 2.5" x .065" aluminum, the pic rail is from raw extrusion and milled to fit the shroud. The red dot is $30 Amazon and the light holder is a cheapy. Nearly everything is either scratch made or highly modified. There are 4 components with single-point threads I cut on a lathe. It's not particularly powerful and it was never intended to be. You can buy stuff on amazon the probably shoots as well or further. This was designed as a cool looking and novelty gift. |

That’s cool, KUDOS to you for going all-in on a fun idea.
Your neighbor’s husband will love that thing and be the envy of everyone. I’m sure you already have another project in mind, can’t wait to see. If this was in the OT forum I would say you need to “post pictures of the neighbor...” |

Nah, I checked. Any propellant that combusts has been deemed a firearm in CA. So, the old hairspray (WD-40, starter fluid, etc) potato guns are "firearms" and need to be dealt with accordingly, but not necessarily banned. But this is compressed air, same as a paintball gun, t-shirt cannon, etc.. You can buy a similar functioning gun on amazon.

That is awesome!
If you were to make another one... How much would it cost to have it shipped to me?!

HB, it's just a single shot per charge. You could hook a compressor hose on and let it recharge between shots, but its still a muzzle loader. So, you'd be loading "hot".
As you can see, it was an exercise in creating something 'adequately excessive'. Like steampunk, tacti-cool is kind of a underground art. Or at least that was my goal. It's not particularly powerful, but with 150 psi, it will launch a mini (1.9") dog tennis ball about 150 yds. I don't know about potatoes. You wouldn't want to have one hit you up close. |

You need to make a steampunk version.

OP, how does this function? Is there a hopper? Semi-auto? Single shot?

OK
So.... if one was to make a sabot.... say take a Red Solo cup trim it short so it is 2" for the bore..... fill a water balloon to fit inside the red solo cup sabot.... maybe a 12 oz coffee cup would be a better sabot https://www.solocup.com/products/12-oz-hot-cup-to-go/ how far and fast could you shoot a water balloon?

I made a potato cannon with a big piece of pipe, a reducer, and small piece of pipe when I was a kid. I used a twist flint sparker to ignite it, and swabbed gasoline inside the chamber for the combustion. The big pipe had a screw-lid. Probably could have blown up in my hands, luckily it never did.
Not to be a debbie downer, but if that blows up and injures the person you made it for, can they sue you?
