Potato Gun Ignitor

I used Rave hairspray in mine. I made my barrel 3' long and just large enough to shoot a golfball. I used a papertowel folded in squares as wadding. I could shoot a golfball out of sight. I had a grill igniter epoxied into the 4"x12" chamber with a screw type cleanout at the back. I didnt glue the barrel to the reducer, I drilled a hole all the way thru it and used a 16d nail. The nail doubled as a stop for the wadding.
 
mine uses air press put a lug nut though j10 hood and door at 30 yards , but aqua net would work good on yours.
 
I see a whole lot of potential for another "HEY YA'LL! WATCH THIS" kinda thing happening.....

~Take a cheap tazer and wire it to long 1/4 20 screws that come in from angles and make a 3 inch spark plug type gap.
I use 3 rows of these wired in series.
~Map gas or propane along with a little shot of Nitrous for an oxidizer. Yes. Nitrous.
~I mounted a cheap computer cooling fan in the fire chamber at the same end as the screw on cap. It is wired to a small button switch to evacuate the smoke and fill it with fresh air. Made a big difference.
~Make sure your materials and construction are up to par. There are many web sites to aid you in this.
~Fog the interior of the barrel with WD 40 to reduce drag speed up the projectile.
~You have just entered into the real world of lauching taters! Shoot it a night and the whole gun will glow orange thru the schedule 80 PVC!
Lets see some video of your best shots!
 
Hell...at least pictures...
 
White Rain Hairspray!!!!


I've tried all the fuels.

a .5 second burst of white rain, two waves with the cap, then screw her on. Hole through plywood, every time!

All the guns that have exploded, all came apart at the rear where the screw cap is attached. Never had one to explode the middle of the gun.

Good Times
 
You guys could graduate to mechanical tubing, a little lathe work + fuse and black powder. Works for some guys I know.

The scariest tater gun incident I've seen however involved acytelene and oxygen, friend nearly lost his fingers.
He didn't give up and just welded one up out of DOM and larger Sch 40 galv. pipe with appropriate bell reducers and such.
 
What a frozen roma tomato will do to 1/8" aluminum:

starting fluid, and black powder seem to work well.

shooting a golf ball at a truck bed will leave the dimples from the golf ball in the sheet steel at 25'
 
Another vote for compressed air!

You can get way more distance, more controllable, and greatly increases the range of objects you can propel.
 
My air cannon has a very satisfying THWOMP! type boom to it.
I always wanted to build one with a 6" diameter barrel and see how far I could shoot a cat.

btw- I live on Hwy 65 and I can see the water tower at the Walnut Cove Reynolds storage facility ...... I estimate it to be 1/4 mile er so.
The cat thing is a pipe dream, but I see that tower every time I turn down my street and wonder what it would take to hit it.

I built a little one (4 foot long x 1 1/2" barrel, 4'' by 12'' air chamber) that I shoot on 125psi of compressed air. It is fun to fill the barrel up with water and shoot it over a group of people. Cools everyone off and entertains at the same time. I have thought about using rubbin alkyhawl and shooting it over a lit wick at the end of the barrel. Hmmmm...911...hello?:shaking:

I use a push button grill lighter for mine.. I left a potato in my gun out in the hot sun for a couple weeks so it smells like a dead body not to mention its pretty gummed up from use so thats prolly why its not firing... I like the golfball idea, so I could just hook an aircompressor up to it and release the valve and I will pretty much have made an 120 calibur cannon? .. Time to get back to workin on a new gun!
 
You can use a batt operater sprinkler valve or a hand operated ball valve and lube it up good so you can snatch it open real quick and easy. I like my air gun for its stealth capabilities.You can shoot a irratating dog in the ass while he is taking a :poop: in your front yard and no body hears a thing but the yelpppppp!:lol: A dog running from an attacking invisable force with crap still comming out, is a pretty funny sight! Not that I've ever seen such a sight. Or fired such a weapon.
