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.

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?

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?

hi again all i posted a question with a other potato problem, nobody answered but i fixed it..Now i got other problem.. what i do is (i tried with deo hairspray 3 diffrend igniters and air duste) and they're all flameable, i found out tha air duster is easist to ignite what i do is first i blow much air duster in, then i blow it test it blow more test blow test, but it simply wont ignite:-( hope you can help oh and 1 more thing, when i open the pill bottle thing it does ignite like it flames out of the wrong end-_-

I've been trying to make a mini spud gun, but all the instructables say that you need a long nosed lighter or grill lighter. Can the piezo electric ignitor be found in a cigarette lighter. I have no experience whatsoever in these type of things, so an explanation would be helpful. Thanks.

Question by GianniMora 9 years ago | last reply 9 years ago
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:https://www.instructables.com/community/best_chamber_to_barrel_ratio/(once again if you have found my research incorrect please tell me, I wont get fired up =)

I just finished making my first potato cannon. I'm only waiting for the cement to dry, but everything else is done. The cement should be dry in a few hours. Just for kicks, I would like to have a cool name for it, though. so, A) What should I name it? and B) how should I apply (paint, write, etc.) the name onto the spud gun? Thanks, Noahh UPDATE: I ended up named it "Pomme de Terror". Get it? Pomme de Terre is potato in french. Terre? Terror? Classic!

Question by noeyebrows1997 9 years ago
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!

Question by benderc 10 years ago | last reply 10 years ago
So i spent the last few weeks designing and building a very nice powerful and yet simple propane spud gun. When i first realized i was going the cleaner burning more powerful propane way, i came to Instructables first. but after some hard looking i found nothing on these cannons, so i made my own plans fros online sights with chamber calculations and what not. Based on my results i felt it neccesary to post my results and what ive discovered about this cannon, however i am always busy and im just wondering if it is worth the time, if there is anyone else out there looking for plans for a successful cannon like i was.
Question by knex luver234 6 years ago
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

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 ).
Question by nutsandbolts_64 9 years ago | last reply 9 years ago
Is there any accurate snipers that i can make that r not powered by compressed air? Ive tried glove guns they aren't that good i don't think a spud gun would be accurate either.
I just built a big piston valved spud gun. I can't get it to fire. When I release the pilot valve no air even comes out. The piston is sealing though. I think it might be theres not enough air in it. I charge it using a 1.5 gallon compressor at 100 psi. The chamber is 5 foot of 3 inch tubing. I don't know why no air even comes out of the pilot valve. I know their isn't leaks or none big enough to hear.
Topic by thejrb 10 years ago | last reply 9 years ago
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.

This is my first post so i don't know exactly what to do. Here is a video of my marble gun it can shoot semi auto or single shot. i became interested in these because of spudfiles.com now i have a site that sells them it is freewebs.com/pats-spuds so you can check that out too. the gun only cost about $45 to make. in single shot at 70 psi the marble will go through a 3/4inch piece of plywood.the video is shot using semiauto at 35psi because that is as high as my pump will go. hope you like it.

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.

I just watched a Mythbusters where they made a pneumatic soda can gun. Go to 5:50 in this video to see their description of it. Go to 7:00 to see it in action. http://www.youtube.com/watch?v=ZMYuQ5daXxk&feature;=related My questions are: what is the "fast acting valve" he used? How do you refill that thing? Anyone seen an instructable for something similar? I've seen lots of PVC versions, but I like the metal version because it's sexier looking, and potentially higher pressure/power. Thanks!
