Spud Gun Ammo!

Hey guys I'm going to make a pnuematic spud gun soon, but I'm going to use something besides potatoes. I figure it'll have a 1-inch diameter barrel, so what can I shoot that's plentiful? Ideally, it would be bio-degradable or otherwise unharmful to the environment. Cork perhaps?

Spud Gun Cartridges

Is there any way that I can make cartridges for my spud gun? I plan on making a new gun anyways. I plan on using this to pwn at airsoft, kind of like Hellboy's big ass gun. The problem is that it takes too long to reload and during that time, im dead in the water. I tried a two man team, but its still too slow. You know how the musket went from power, paper, blah, blah projectile? Thats how the spud gun is now. I need it to be what modern guns are, where the bullet, powder and firing cap are all in one unit... I just need plans... My fuel is 91% achl.

Spud gun materials

I'm building a spud gun and all I could get was cellular core ABS, it seems pretty light and I'm not sure if I can trust it.  Would PVC be a better choice to handle the pressure?

ABS or PVC for a spud gun?

All I could get at the local store was cellular core ABS but I'm having second thoughts as to its strength.  Can PVC handle pressure better and therefore be safer?

Golf ball launcher/ spud rifle long range

A golf ball will traver about 3X farther than a smoth round object .  This brings a spud/rifle to a whole new level.. Golf balls now come with 350 to 450 dimples to disrupt the lamar flow and decrease drag.  The ?? test guys did this to a car and got 10% better gas-milage on their first try.  I've thought about this for a longtime now .., I need some help tho,.or I wont ever get to It.  There is a recient article here on a hi power or long range spud rifle that looked good for a launcher, but it mite now be strong enuf for a 45 grain ball? Some ball did come with just a band of dimples so the ball would stabllise in flight and not climb or divert from the spin all golf clubs have built into their faces 7degrees?  I believe they were outlawed since they would be more accurate on drives.  It mite be good for this launcher tho?   Thanx

Air cannon/spud gun trigger Answered

I've opted to go for the modded sprinkler valve trigger. My questions are thus: Where can I find the required 'blow gun'? What is the 'blow gun' for when not killing potatoes? Will the valve reseal if the trigger is released before all the pressure in the tank is gone? So, can you fire more than once before pumping up again?

Where do you buy a cheap bicycle pump? Answered

 Please note that most shops here sell "Made in China" products and the only places that you can trust is Ace Hardware, Home Depot ( do they even sell bicycle pumps? ) and some vendors in Manila. Like, seriously, the stuff they sell in Manila is cheap, strong and hard to find. I just need one to power my air cannon and impress my teacher and finally get to get some people to say "WHOAA!!!!". Oh, and it should be Php.150 or lower ( $3 equivalent ).

Optimisation of pneumatics

Another interesting thing I found through research, a flaw in most over-under designs and pressurizing the stock, I have found that for every 90 degree elbow between the chamber and the barrel the resistance to the air is the same as adding 20 feet of straight pipe, this can be changes by using two 45 degree fittings put together to make a gentler turn or by using curved fittings instead of elbows, the gentler the turn the better. From this I have found that the simple straight cannon with the chamber directly behind the barrel as is shown in the picture below (please note this cannon is one I found from Google just to emphasize the point, and this is in pneumatics only). also to increase efficiency look at my other topic: again if you have found my research incorrect please tell me, I wont get fired up =)

best chamber to barrel ratio

Okay I have not built a cannon yet as such, as I am going to make my first one awesome but I've done some research and found the golden ratio for efficiency for chamber-barrel size, assuming the chamber is always the same volume a chamber is 1.6, now I'm guessing a bit from now on but it seems that that maximum efficiency is approximately 1.61803399 or the golden ratio that keeps appearing in our world, I just thought you guys would like to know for the design stage as this is what I'm going to be using when I make my gun. also is it worth spending extra for a high flow blowgun over a normal one for the pilot valve to my 1" sprinkler or wont it make a noticeable difference P.S. if my calculations are wrong please, if you know more ( I'm only 13) please correct me. I have worked this out from pneumatics, not combustion's or hybrids. expect to see my gun soon!

Pneumatic Toilet Paper/Spud Air Cannon-

This is a project I'm wiling on with my little brother. I'm building a cannon out of PVC. I want it to be able to shoot four times without adding air again. So my idea was to make four chambers to store the air. Each chamber would have an individual ball valve. Then another ball valve where the chambers stem into the main body and barrel of the cannon. From the three inch PVC Im going to drop back down to 2"-2.5"  PVC for a more forced compression, then the barrel will be 4". I understand that PSI is a pressure measurement, however I'd assume that my PSI's wouldn't be able to exceed the lowest grade of PVC I build with? That would only make since.  The problem I'm having is, I'm not sure if any stores such as home depot or lowes has couplets that could couple 4" and 3" as well as 3" to 2". I also need to know what kind of pressure would I need to get to launch toilet paper into about a 10-15 foot height? Or would this just be a trial and error experiment?  Thanks for all help. It's much appreciated!

Why doesn't my potato cannon work? Answered

Today, I finally got to test my spud gun. I loaded it up with a plug of potato, sprayed in one second of hairspray, twisted the cap shut, and pressed the barbecue ignitor. I heard the ignitor work, but nothing happened. I tried this again and again, using different potatoes, cleaning the cannon, and checking the sparker. Every time I did it, it didn't work. I followed the instructions step by step from Backyard Ballistics, but I used ABS instead of PVC. I also used a barbecue ignitor instead of a lantern ignitor. I used all ABS parts, with the right cement for ABS, so I don't know what went wrong. Could it be my hairspray? I bought a $1 can, which seemed a little strange, because all the other cans were at least five dollars. Is cheap hairspray made with different chemicals? I believe the hairspray brand I used was called "White Rain", but I could be completely making that up.  Thanks, Noahh

Very nice propane spud gun with range of 150-200 yards for under 100$ should i post?

Growing Grub

Here in France we suffer a lot with doryphores (Colorado Beetle). For the last few years I have grown my potatoes in straw which does seem to have reduced the number of beetles I've had to put up with. 1) A week or so before planting time (or, if you want to try and conserve water do this in winter), break open a few bales of straw and lay the wedges - tightly together - over your spud patch. 2) Soak for several days until saturated. (if doing over winter then forget this stage. The rain will do it for you) 3) Lay seed spuds over the soaked wedges and cover with loose straw. As the spuds grow just "earth up" with more loose straw 4) From time to time check the bottom is still damp. Water if required. I find that I rarely have to water 5)To harvest, or if you want just a few New Spuds, lift the loose straw and take what is wanted. 6) After all the spuds have been harvested you can either leave the straw in situ and re-use next year, dig it into the ground or move to a manure/compost heap to finish rotting down. Sorry I haven't got any pics. I didn't think of taking any as I've used this method for a few years and I've also broken my camera when I had a fall. Haz

Airsoft/Spudgun crossover: Anti-Personnel Explosive thingies

Its a PVC/ABS thing that works like a spud gun, but launches a powder cloud (and potentially BB's). It's remote-triggered, so it can be buried underground, and only the top has to be removed, so it can be permanent. It works in the same way as a spud gun. I'll try to get diagrams up tomorrow, and if I can build it, pictures and an instructable, of course.

Could an O2 sensor from an automobile be used inside the combustion chamber of a potato gun?

So I was shooting my potato gun after talking about car repair today, when I got the idea. Could an O2 sensor from an automobile be used inside the combustion chamber of a potato gun to achieve optimal fuel/air ratio? Finding the chemistry of the aerosol fuel would be difficult, and I wouldn't know where to start with the computer stuff, but could it be done? If so, has anyone done it? I searched instructables and no one has even mentioned it. I found on a mazda forum that a wideband O2 sensor may detect the air/fuel ration when using propane, but what about aerosol? Propane in a plastic gun is just begging for injury. I use Right Guard sport deodorant (Without antiperspirant) as the fuel, I think it works the best. The primary ingredient is Denatured Alcohol.
