Me and a couple of friends just built some potatoe cannons and we
found that limes are much better than spuds.  They flew
significantly farther,  and cost about the same. If the lime is a
little too big for the barrel we would just roll it under our foot
until it was softened some. Then we would use some soap to lube the
barrel slightly.   I think though when limes go out of season they
will probably cost alot more but it is definately worth trying...

you can also sand or cut and outer edge of the barrel opening to be
sharp like a knife, this will make fitting produce easier

We do that with potatoes but have found that limes are best left
uncut.

Take a look at our new online store and browse through our several
electric spark ignition, combustion potato guns.  We also supply
reusable potato gun ammunition, our very own Spud Bombs.  Take a
look around, and contact us with any questions you have.

it looks good I would like to see a couple of close ups of the cannon
good job

can anyone tell me where to find a set of blueprints or send me a few

sure what do you want to shoot? look at some of mine in the jeezer
folder and let me know.

I posted some pics of my Bud-Zooka, Im bud and its a zooka, pretty
standard, but fun as hell....

Hello, Pressurized_air_cannons member.

I have built my second Full Scale Civil War Air Cannon.  This guy
has so much power, it is impressive.  It was made to launch tennis
balls or rolled t-shirts.  You can see some of our cannons at
www.VicksburgCannons.com the air cannon is exactly the same as
cannons pictured but with an air nipple for pressurizing.  Anyone
interested in a full scale barrel, let me know I will sell my first
2.  Starting my 3rd tomorrow.  Just send me an email.  Carriages are
seperate.

Cool group! I'm very happy to join in the fun.  I'm a machinist and
tinkerer and have alot of gun experience and have always wanted to join
in learning more about this "sport" ever since a friend of mine fired a
potatoe across the ramp over a runway to another hanger many yards
away.  In fact alot of people are using home made cannons to scare off
birds [which are pests to pilots wanting to fly safely] from the ends
of runways now.

Hello gents, I'm interested in buying the perfect paint-ball cannon
if it already exists and would like to build one if it doesn't.
    I want the cannon to be as noise-less as possible while still
being able to launch a softball-sized, to plastic (basketball sized)
beach ball atleast 200 feet accuratly, is this concept already on
someone's drawing board or in production, if so let me know, I'm in
the Charlotte area of North Carolina and you can reach me at
thepitbroker@...    thanks, JR

Hey gang!
      New to the group, have built several combustion cannon up to a
3.00 calibre and one for frozen water bottles that went through 1"
ply
at 30yrd.  This was all fun but would like to build a pneumatic gun
because my nephew is now old enough to get in on the fun but don't
like
the idea of him using cumbustible fluids if I am not around, so I
think
I will start him off with air power.  So when he is legally
responsible
for himself then maybe I'll let him go for butane power.  The only
pneumatic gun I ever built was in the 10th grade for an engineering
project that shot ping-pong balls and used only .9psi.  Should be fun!

Actually pneumatic guns are, in some ways, more dangerous than combustible. Combustion guns only shoot at around 20 to 30 PSI whereas pneumatically operated guns can shoot at over 100 PSI. So there's the danger of the speed of the projectile. There's also some danger in the idea of a pressurized PVC tank. PVC is known to explode into tiny pieces at larger pressures. And PVC wears down with age so the older the gun the more the "oh darn, that wasn't supposed to happen" factor increases.

In my opinion Pneumatic is definitely more fun with more choices to experiment with. Although some of the above contingencies are few and far between, don't just assume that since nothing is exploding it's safe. If ya want a few plans for pneumatic guns drop me a line and I'll put together a few links...

I saw your profile at yahoo.com. I'm so interested in you,
so I have updated my hot pictures to my account from my

23 years ago, I was one of the first people to sign up for a coupon
program (listed below). Despite many people telling me not to because
the company was brand new and the concept seemed to good to be true,
I didn't listen and signed up and I am so glad I did! The savings
were and for 23 years have been outstanding. What I like most about
this company is that they seem to always be researching new programs
to save us more money. Shortly after the coupon book they released a
Kodak film developing and free film program, a few years later they
released an online wholesale gift mall and as seen on tv one stop
store for all the items seen on tv infomercials and most recently
they released the restaurant gift certificate program. I am quite
happy to say that I joined everything that they released and each
program has proven to save me substantial money. I only wish I had
tracked my total savings over the years it must be at least one
hundred thousand dollars! I thought I would share with you my first
hand experiences with this company, here is a copy of the post I read
originally:

Copy of Post:

As amazing as it may sound many people do not realize how easy it is
to LEGALLY stop paying for their groceries! This is how the one hour
television show began for the company whose website is at:
http://savemorethanever.com I thought it was very interesting and
decided to check it out. I am very skeptical by nature so the first
thing I did was check out the company. I contacted the Better
Business Bureau and found that the company has had no complaints
lodged against them, I also contacted Paypal who has verified this
company. They told me that they verified the company's licenses,
bank accounts and other paperwork indicating to them that the
company is legitimate. Then I started asking co-workers and friends
about this program and to my surprise 6 out of the 10 people that I
spoke with were already using this program. They told me how pleased
they were with it and how much money they had saved and are
currently saving. So I decided to sign up for their sampler special
program on 7/26/05. On 8/2/05 I received my complete membership
package and the fun began. Using their program and the free lifetime
membership that it includes I went to the supermarket ready to make a
killing. The cashier rang up my grocery bill and it came out to
$239.87 then I presented her with the coupons I received from this
program and I saved $223.38 - my final bill was only $16.49! The
cashier wasn't the only one shocked. This program has changed my
life!

I have to strongly agree with the recommendations I have heard about the company
at http://savemorethanever.com . I am going to share my actual receipts with you
at http://actualreceipts.visit.ws to show how absolutely amazing this program
is. I will be adding many more receipts in the weeks to follow.Ten years ago I
joined their grocery coupon program and since that time I have been saving a ton
of money every week. In fact in the ten years that have past I can't even
imagine how many of my friends and family members have joined after witnessing
the amount of money that I have saved. The best part is that this company keeps
coming out with new and innovative savings programs. I have joined them all and
I must tell you that they all work incredibly. A couple of years ago I asked
them how it could be that every program they offer works and I was told that
they actually test them prior to offering them and that for every program they
offer, dozens are rejected because they do not meet their standards. It is an
incredible benefit to have a company test these programs so that we don't have
to. I just can't wait until they release their next program! The savings keep
getting bigger and bigger!

Download the high-res if you have the bandwidth...... What more need I
say? ;-)

If I were to run a pair of these valves, or even one, does the
valve, when modified, automatically reset after firing if I
continually feed air to it? Obviously I would close whatever valve
I'm using for a trigger. I don't want to have to turn my air supply
off.

Thanks!

Someone is very insterested in you! Check the profiles here:

Some of my friends have managed to meet a few   nice ones off this thing (here
is the place they told me: http://www.liveview.info/qievh , but what do you guys
reckon? Myself, I actually think it is pretty awesome from what I've seen, and
Im considering getting on there later on this evening. If you don't know what
it is, basically its like a matchingplace, but has few added things I noticed.
Stuff like messenger, vidchat, picsrate, etc. Best part is you can talk to ppl
on vidchat        even if you don't have it enabled yourself.

Hi all. I've built an air cannon using a 1"/25mm sprinkler solenoid
valve as the release. For some reason though I get air flowing through
the valve into the barrel, preventing any significant build up of
pressure. Thinking I had a faulty valve, I bought a similar but
different brand valve and had the same problem. I was wondering if
anyone else has had the same problem and whether I'm doing something
wrong. I've pulled the first valve apart several times to try and work
it out. I think the diaphram doesn't seal properly.

Are you sure it's leaking into the barrel? I've had issues with air
leaking out other places.. If you're sure it's leaking out into the
barrel you could try cleaning the diaphragm..

Make sure the manual release is screwed in all the way too..

Thanks Jesse, but yeah, I'm positive. You can put your hand over the
end of the barrel and feel the air coming out. T

he diaphragm looks clean. Theres a plastic round thing that sits under
the diaphragm inside the inlet part that seems to form the seal with
the diaphragm, and I'm starting to think that is the only place it
could be leaking. I will investigate further.

BTW I'm still open to suggestions.

I wanna be your SEX partner! pls check my sexy photos here:

Hiya all, lets see if we can get some activity going here. I posted
way back with my version of the "TaterHater". I have a vid on
Kontraband at http://tinyurl.com/dpngx . There is a smaller, lower
res version at www.xr650r.us/video/ under "taterhater". The K-Band
vid is much better, much higher res and audio quality.

  Anyway, since making the vid I have upgraded the cannon to using 2"
feeders from the rezzies to the 2" barrel. The PVC ball valve has
been replaced by a 1.5" brass ball valve FREE from one of my
customers. Performance was enhanced phenomonally! The 2" steel slugs
are flying roughly 750' when lobbed at a steep, 80 degreeish, angle.

  The cannon is now mounted on a post set in the yard. No kick!

A few sources of ammo no one has mentioned before:

Stale Dunkin Donuts donut holes. The jelly filleds make nice
gruesome splat effects!

RedBull cans. Made for cannon launching. Air tight fit in a 2"
barrel! Fill with sand or concrete. Wet sand works best.

Caulking tubes. Find one 1/4 full and these things are almost as
good as the next idea....

The best? Poly sealant tubes used by windshield installers. They are
made of aluminum! Get one 1/3 full and they leave the barrel with a
very satisfying snap, headed for a straight as an arrow flight of
900 feet! I visit or pass by several of these guys on my daily runs.
I have a box of about 50 now that will soon be sitting in a jig to
have ballast added.

  Oh, BTW, the 2" slugs I've been using? (Insert schoolgirl giggle
here) They WILL completely pass through a 1971 house trailer at a
range of 450'!!!!! Glad I missed the fine china!

Enjoy all, and be safe......

I know a couple      of friends already who have met a few nice honey’s off of
this kind of stuff (here is the site they use:
http://www.simplefuneasy.info/mlfk , but what do you   think? I think it is
pretty cool from what I saw at my friend’s house, and am thinking of signing up
later today. Basically it's a regular personalssite, but with an instant message
and Webcam system built in. Basically you join their chat-room on their site it
gives you a link to those people online in the chat-room, their location, their
picture, etc and at one click you can start chatting to them over Webcam (even
if you don't have one). Pretty nifty stuff I think!
