Ural Mounted Tennis Ball Cannon

[eatmyjeep]

it will fly farther if you compress the gas... ( ie. push the ball in after you gas it up.)

[Drofeddamite]

do you think you could make a compressed air version with car opperated tyre pump to provide the pressure

[KanzlerM]

@Drofeddamite

It would probably take quite a bit of air (large storage tank & quite a bit of time to

re-pressurize between shots). It would be quieter, and probably not draw ire

from neighbors & law enforcement... but the kaboom is part of the fun for me.

You can make an automated one which uses propane so that all you do is

put in the tennis bal, push a "charge" button and then push an "ignite" button.

The air fuel mix with propane can be tricky though.

Build one of these and become the first kid on your block to be the last kid on your block.

@KevinByrne2

It's only a tennis ball - the velocity is about the same as a tennis ball hit

hard by a tennis racket (think how far a pro player could hit a tennis ball)

It MIGHT leave a bruise, but it's not like being hit by a fastball in baseball.

[JuanPapaNicolao]

how far did that tennis ball go

[KanzlerM]

@JuanPapaNicolao

I have no idea. It shot into the forest. My dog brought it back a day or two later.

He managed to find all of the ones I shot out there (3 or 4)

[JuanPapaNicolao]

@KanzlerM wow id like to shoot my neighbors house with that thing lol

i made the newton's petard from the book, but i turned the compression chamber so it's straight instead of up and down so i can run around with it in airsoft wars and shoot wads of paper filled with bb's

[mhaddadi]

How did Ural reached America? Soposed to be Russian?

[KanzlerM]

I added a link at the bottom of the description (info) at right --->

[mrfish1991]

That backyard ballistics book is awsome

[KanzlerM]

I like the book.

Most of the info is on the internet, but it's nice to have it in print and gathered into one book.

Some of the info on the internet is improved upon what's in the book, but the book is still worth what it costs on Amazon.
