There really isn't a best fuel for a combustion spud gun. If you want to get the maximum muzzle velocity from a gun the difference between the various fuels is relatively small. A typical combustion spud gun has so much shot to. Reference Implementation of a Spud Gun. My potato cannon is fairly vanilla as combustion powered spud guns go... As mentioned above, it uses a chamber made from a 4 inch PVC coupler with a 4in-to-3in reducer and a 3in cleanout cap on the butt end and a 4in-to-3in reducer followed by a 3in-to-1½in coupler on the barrel end and a 1½in barrel My crazy dog loves this cannon. Her name is Freedom. This tennis ball launcher can send a the ball out of sight. It uses Mapp Gas or Propane for propellant..
. The barrel is made out of 2 PVC pipe and the combustion chamber is made out of 4 PVC pipe. The pieces are joined together with an adapter. When you fill the combustion chamber with fuel, like hairspray, and trigger it with a spark, it will combust and send. The potato cannon, a.k.a. the spud gun, is a popular and very entertaining amateur science project. It's simple to make, and few devices offer such bang for the buck. You can use the Night Lighter both day and night, but when it's dark, the clear PVC provides an excellent view of the interior ballistics. Also, the stun gun gives bette Who needs guns that shoot bullets when you can fire a ball of plasma? The 'plasma popper' is a slice of future created by Mr. Al Stahler.It's an ingenious use of transparent plastic tubing and an ignited ball of methylacetylene-propadiene propane (MAPP gas). It isn't a kid's toy, but it sure does look pretty when you use it at night

The gun rarely needs cleaning, as it blast-cleans itself every shot. The MAPP gas does not leave behind water vapor like propane does. The only residue is tiny flakes of spud from the cutting action. The flakes tend to blast out as yellow sparks. The outside gets pretty sloppy, as the leftover ring of cut spud gets pulverized when the breech. How to Build a Potato Gun October 2003.

A potato cannon is a pipe-based cannon which uses air pressure (), or combustion of a flammable gas (aerosol, propane, etc.), to launch projectiles at high speeds. They are built to fire chunks of potato, as a hobby, or to fire other sorts of projectiles, for practical use. Projectiles or failing guns can be dangerous and result in life-threatening injuries, including cranial fractures.
Well my name is Kenny, and the gun pictured below is Big Bertha has a 4 chamber and 2 barrel. Runs on 7 second injections of Mapp gas (in the picture) and launches rocks and whatever else will fit in the barrel. For more details you can contact, Ken Blan at firstname.lastname@example.org This is the newest edition to our spudgun collection I did not grade based on optimum specifications. I cared more about the intent to instruct. I did not judge based on the chosen chamber-to-barrel ratio. I have seen anywhere from 2.2:1 all the way to .6:1. I sorted through a variety of terms to be sure to be inclusive: spud gun, potato cannon, tater taser, potato gun. Disclaimer Propane and MAPP gas are much more sensitive to air/fuel ratio.

It's not the same thing, because the IC engine compresses the fuel-air mixture before sparking it. However I have seen potatoes, or pieces of them, thrown great distances, from a potato cannon, at an elevation approximately 6000 feet above sea level. It may be the case that potato guns, I mean the fuel-air mixtures therein, are harder to ignite at higher elevations
Notes on a very bad analysis of spud gun fuels from a group that should know better In 2013 a short paper was published in Eur. J.

Variation of Quantity Bundles Available (2) 4.6 out of 5 stars 85 The gun will put a marble through a piece of 3/4 inch (19 mm) particle board or plywood. I managed to put a hole through 1 1/4 (30 mm) particle board with a steel ball. 5/8 Steel balls weigh about three times as much as marbles, so they pack more of a punch. I got these from an industrial bearing store, but they cost $1 each
I was inspired to make one myself and experiment with different tubes, lengths of tube and size of cannon. Ultimately, I came up with a massive Propane Fireball Cannon with spiraling tubes of blue fireballs! While I call this a Propane Fireball Cannon I chose to use MAP gas instead of propane as my fuel. The original MAPP gas, which stands My HS physics project was a potato gun that shot golf balls. Same basic design but the barrel was lined with cardboard and greased up with Vaseline. We used MAPP gas and Oxygen which were electronically metered- 2 shots of Oxygen, 1 of MAPP, IIRC we got it past 700y at a 45 degree angle. That thing was deadly MAPP gas torches burn hotter than propane, making them a better choice for modern solder. Five to 10 seconds of heating with a MAPP gas torch is all that's required before you can feed solder into most 1/2- to 3/4-in. pipes and fittings. Be careful, though. It's easier to overheat a joint with MAPP gas

You will need the following Materials and Tools: Half Sheet of Copper - 3 ft by 4 ft ( use 18 gauge copper) Amazon has some reasonable priced copper sheets; Roll of Solder - Try to get hold of a roll of 95/5 tin/silver is the best and stay away from anything with cadmium/antimony or lead in it.; Rivets - stainless steel or copper; 1/4 copper tubing - 8 ft should d
MAPP is an acronym for methylacetylene-propadiene propane, which were its main ingredients, although it also contained iso-butane and butane.MAPP gas turned out to be less than ideal for welding steel because of its high hydrogen content, and it burned slightly too hot to be safe for soldering Also, the pneumatic launchers are between 2 and 4 times more powerful than the combustion spud guns, (i.e. hair spray/ether ignition source launchers). I build them with interchangeable barrels, i.e. Paint ball, 50 caliber, 75 caliber, 100 caliber, 125 caliber, 150 caliber, 200 caliber and 250 caliber Paint balls are my favorite, though apples.

I've used Bernzomatic torches for decades, they work well. Solid brass construction and is designed for a standard (narrow / tall) 14.1 oz propane tank. It will also fit the (fat / short) 16 oz tanks (same fitting) used on portable grills. The 'fat' tanks are harder to hold. I did not try it on MAPP gas; as they don't recommend it for this unit Step 3: Place the two parts together and begin apply heat with either a propane or MAPP Gas torch to the copper. Don't directly heat the stainless steel. Once the solder begins to melt onto the copper move the heat onto the stainless steel. Heat until you see the solder flow into the joint. Then remove heat source
Preheat the aluminum with a torch methylacetylene propadiene propane (MAPP) gas torch. You can also use an Oxy acetylene torch but I prefer MAPP.

The combustion chamber was 6 dia and about 18 long with 2 spark gap igniters positioned on the axis of the cylinder 1/4 of the way from each end. If I blocked the barrel with just a crumpled up piece of paper and fired it the, the cannon would still make a large boom I decided to use MAPP gas as the propelant, no dickin around with whimpy hair spray. Long story short, the thing blo up in my hands when i fired it, the potato did leave the canon, but the gas exploded so quickly that the potato could not accelerate fat enough to prevent the PVC from reaching 280 P.S.I. i lost most of the hair on the right side. 315214 do-it-best/hwi products mapp gas 14.1-oz cylinder mapp gas - jwh315214 > I built a spud gun with a 4 inch wide barrel that is 2 feet long. the barrel is 2 inches wide and 4 feet long.

Durable and powerful, this weed burner has a sturdy all-metal design. It is compatible with a small propane or MAPP gas canister and produces a 20,000 BTU flame that quickly burns up weeds that are growing on your lawn, garden, or along a pathway. You can even use the weed burner to light up your fire pit or de-ice your driveway MAPP/air has a temperature of about 3600 degrees F which should melt steel. The Turbo Torch catalog lists the smaller (#3, #4, and #5) torch heads at 1800 BTUs. When I'm getting around better (hip replacement three weeks ago, so lots of time to roam the internet, daydream and pose questions) I'm going to try my Bernomatic 4000 and see how it does I made a potato gun years ago, but not just any ole spud gun--it was gas fired, piezo ignition, and set up as a bazooka, shoulder fired. I used acetylene or MAPP gas and oxygen in it; instead of the usual sound a potato gun makes, this thing went off like a stick of dynamite I used a BenchSource gas annealer for 4-5 years and it was okay, but a PITA when changing cartridges, because of having to rearrange torches and reset dwell time. Last year I bought an AMP unit and I have no doubt, it's the most precise, repeatable annealer out there.
