SpudFiles

Ive done my little spudgun last week using a 16mm tube barrel from PVC.

Today i was thinking for my next spudgun.
And yes !



A Double Barrel shotgun !!

when i was home directly photoshopped my idea !

The barrel is a 19mm from electric tube PVC.
Under the barrel there is a 16mm Tube with a small 19mm tube over it,
connected to the 19mm barrel. So the barrel can slide into the combustion chamber's 19mm connection piece.

Using a small weller butane refill can for fuel.

And a BBQ ignition to shoot.







Only need something to let fresh air in when i need to reload it.

But this is a basic idea

Use a couple of small computer fans you can get the pretty cheap at radio shack or online

hmmm not bad idea... maybe i can combine it with a rubber membrane


like this

ahh i see the rubber piece is like a flap 8) i f you want it to look cooler mount it ona shot gun stock an hinge the barrel so that it loads like a real double barrel shot gun lol any ways i like you idea and i hope you make it

i know what you mean i had that idea to but i need a gas tight connection.
But im afraid the contruction wil not be that strong and not gas tight.

But yeah im going to make this one for sure !

thanks you like the idea !

shopping like a lady !!

Im going to test how much power etc.. the double barrel will have.
Just starting with one gun.

this time bought a much bigger pieces then my first one.

my first gun had a chamber like 50 cm3

And this one has a chamber like 175 cm3 ( 0,175Liter) .

so 3.5 times the power i hope so

and the barrel is bigger. old gun has 16mm this one has a 19mm.

This is basicly the gun.



Drilled a 19mm hole for the tube in an end cap.



Here im going to glue the tube in the end cap inside it self.
Just cut the pipe half away .



Now i am going to find other parts to measure the amount of fuel.

That looks insane. I really want to see it finished now! Nice idea.
btw, what animation program did you use?

Thanks !

I use Photoshop

LOL, thats cool. I want to get photoshop. I have an animation program because I do a bit of animation. It anim8or.
But to keep on topic here, whats your C:B ratio?

i dont have any clue.

LOL, ok, doesnt really matter

i calculated... it would be like 0.8:1.

Oh, OK cool, I dont know much about combustions, so is that a good ratio?

yes that is a very good ratio

did you plan that or was that just a coincidence?

i readed about it. that 0.8:1 is a good ratio.

Then i started calculating.
