Oh wow. Very nice. I didn't think you meant THAT mini.

Interesting. Didn't think lead would do that since its soft and all. But now that i think of it, it makes sense. What were you shooting it from?

Looks like an interesting concept. Although I would be worried about the strength of the balloon.

Oh and wouldn't the pressure in the chamber be higher then that in the ballon which would allow the chamber air to push the ballon out of the way?

More information would be helpful.

Well, one week it worked and the next it didn't. We didn't use it in between.
When we took the Air filter off the carburetter didn't look like it was clogged with anything.

Yeah were getting a spark, i got my dad to hold the spark plug while i pull the cord. He got zapped
Im not sure about the carburetor though, How would i tell if it was broken? And how would i fix it?

Hey guys, Just wondering if you could help me out.
Recently my mower broke (yesterday) :/ and I cant get it to work again.
We have changed the spark plug and cleaned the air filter but thats about as far as our mechanical knowledge goes.

Any help is appreciated. Thanks.

Yeah well... My mum wont let me use anything past its rated pressure D:
And anyway I was thinking of making a high pressure (400psi) 1/2" Pneumatic.

In the world of spuds today I finally found a QEV with a pressure rating higher the 1 bar XD. Its rated to 10bar, 1/2" porting and costs $80 AU. Im sold.

Great looking gun you got there.
Just wondering what you used as a piston?

P.S have you tried using a solid rubber piston yet?

Yeah, I'll ask if i can video it. Or maybe ill just video one of my tests.

@frankrede
You mean like solid at one end and open at the front with maybe some wadding?

Ok, thanks guys for all the reply s.
I have about a month or 2 to complete it so no real hurry there.
I think i'll go for a sabot type of ammo. ill start testing right away

Have you by any chance not read the rules? BTW these are my great grandma's ashes, I don't think i want to go blowing them up anytime soon...

Yeah I was thinking something along the lines of that, although Im not sure about the cartridge thing. I dont really want the ashes coming back...
I'll have to do some testing when i get back to my mums house and my bits and pieces.

Ok, I just got a phone call and i have been told i have a great responsibility...
Recently my great grandma died and got cremated so my family decided they wanted to shoot them out from the top of a mountain. My mum told me i have to make a spud gun to shoot them out of...

Now I'm in need of some ...
