Hey everyone, this is more of a vote thread that anything else.. I have a mauler that needs to be used, and I am at a point where I don't know what to build.. I have two choices:
Simple, yet huge over/under tennis ball cannon
OR
Semi-advanced golf ball cannon, much like Crowley's V.A.L.
On the tennis ball cannon, I will be electrically firing the Mauler via 1 inch Rain Bird sprinkler valve
On the golf ball cannon, I will modify the 1 inch Rain Bird sprinkler valve to pilot the Mauler.
So now, it's up to you.. WHICH SHOULD I BUILD?

Will this be the cannon that will shoot concrete filled tennis balls, which you mentioned in another thread?evanmcorleytv wrote:Simple, yet huge over/under tennis ball cannon

What material will you build with? I'm sure you realize that a concrete filled TB will weigh approx 300 grams and require about 2+kpsi pressure to push it 700 yards. That's a tall order for a Mauler valve, 1 inch Rain Bird sprinkler valve and pvc pipe fittings......but I could be wrong.evanmcorleytv wrote:indeed.velocity3x wrote:Will this be the cannon that will shoot concrete filled tennis balls, which you mentioned in another thread?evanmcorleytv wrote:Simple, yet huge over/under tennis ball cannon

5-6 foot by 5 inch chamber, 10 foot barrel.. I told you it would be huge..
Either that, or I would machine a "scaled-up" version of the valve to make a larger cannon.

There's much more to constructing the device you've described than simply saying......"I told you it would be huge". Based on your performance criteria, I don't think you have a concept of what is involved in a high pressure, high gas volume and flow device....especially one of this size.evanmcorleytv wrote:5-6 foot by 5 inch chamber, 10 foot barrel..

Do you have the machining facilities to produce such a device? Do you have the knowledge, skill and engineering ability to design and produce a device that WILL withstand the extreme forces exerted on components? Do you have a large budget that will allow you to construct this device? Are you willing to devote many, many hours and days to design and construction?
Although constructing a large bore cannon to launch such heavy projectiles 700 yards is a lofty goal, you might consider all that is involved and required to do so.
I think you should be more practical and build the low pressure GB cannon. Which ever you choose to build, I wish you well in your endeavor.

lol... large cannon's take a large amount of time and money to make... trust meevanmcorleytv wrote:5-6 foot by 5 inch chamber, 10 foot barrel.. I told you it would be huge..

That said, this sight could use more of them!

I DO have machining facilities that I can use, I DO have the skill, and knowledge required, and I DO in fact have the budget. Since I live 45 minutes away from a PVC factory, my pipe is incredibly sheap, and also, I meant to say that it SHOULD launch REGULAR tennis balls ABOUT 700 yards.velocity3x wrote:There's much more to constructing the device you've described than simply saying......"I told you it would be huge".

Oh....I too get the words "concrete filled" and "regular" confused when whenever I speak about tennis balls. I really don't know the max range of a regular tennis ball, but a regular tennis ball cannon is certainly a doable project without lots of machining, money and time. I change my vote to a "regular" tennis ball gun.evanmcorleytv wrote:I meant to say that it SHOULD launch REGULAR tennis balls ABOUT 700 yards.

What I meant was that is the maximum distance with a tennis ball. I would still use concrete filled tennis balls for destroying things.velocity3x wrote:Oh....I too get the words "concrete filled" and "regular" confused when whenever I speak about tennis balls.

I don't think you'll be getting even close to 700 yards unless you filled tennis balls with concrete. Normal tennis balls have poor aerodynamics and poor external ballistics (crap sectional density).
Concrete filled tennis balls from your cannon would go roughly 550 yards according to GGDT, that might be optimistic as I used 0.5 for the drag coeff (which is the Cd for a sphere, tennis balls would be worse as they have little hairs on them).

lol don't worry, I will shave my balls.. haha and I would probably end up using racket balls.. I can get them for cheap, not to mention that I could just make my own darts..MrCrowley wrote:I don't think you'll be getting even close to 700 yards unless you filled tennis balls with concrete.

Will take more than shaved balls, I get about 200m on GGDT for tennis balls from your cannon. Even though the range calculator is some-what rudimentary, I don't think those calculations are that far off from real world tests.evanmcorleytv wrote:lol don't worry, I will shave my balls.. haha and I would probably end up using racket balls..

Well, at the moment, it doesn't matter, because I have more votes for the golf ball cannon.. lolMrCrowley wrote:Will take more than shaved balls, I get about 200m on GGDT for tennis balls from your cannon.
