The pee wee fun gun!

[elitesniper]

well my next project is almost complete its a very small high pressure coax http://www.spudfiles.com/forums/mini-co ... 13404.html

[Mitchza89]

Haha what's been putting it on hold mate?

[elitesniper]

just wating to get more parts 8)

[Mitchza89]

Haha that's the way. Geez you can tell I've been spudding for a while, I have that many parts lying around aye. All brass, copper and gal Bling Bling!

[elitesniper]

haha well i just buy the need parts when i start a new project so i dont have many things laying around

[Mitchza89]

The lack of money lying around was the reason I started recylcing parts .

So what's the specs on this little coax anyway mate?

[elitesniper]

how bout we leave it a surprise till i finsh

[Gippeto]

Looking good mitch!

Are you going to "put the coals to it"? I know you have more than 200psi available.

[Mitchza89]

Haha more then definately Gippedo. What gun's are you planning to exploit with your 400psi monster of a pump?

[Gippeto]

That thing was driving me nuts. Significant pressure just waiting to be used, and nothing finished to make use of it!

To avoid the mad house, I have started a copper gun as well.

This should be working by the weekend.

[Mitchza89]

That's going to be so so good. What's the specs on this gun? Or are you keeping it secret?

[Gippeto]

Like the pump, nothing revolutionary, just a culmination of several ideas from varying sources.

Barrel 1/2" x 36"
Chamber 3/4" x 10-14" (not decided yet)
Piston turned from nylon w/ floating o-ring (sorry Jack, no epoxy this time)
I have an old break-barrel that will donate it's stock to the project.

And of course, as much pressure as I can manage.

I'll put it up on it's own thread when it's done.

[STHORNE]

very nice job Mitchza89.

I like the neatness and compacticity (yes, thats right, i just made up my own word) of it. And the fact that you made it from spare parts adds that much more character to the gun.

job well done!

[chartreusesnot]

Is that coaxial? if not, where would the piston go... anyways, assuming it is coaxial, how did you get the metal barrel inside the chamber? is it epoxied or something?

[Mitchza89]

Cheers for the comment Sthorne, I really appreciate it mate.

Chartreusesnot, It's a Coax. The piston is located in the Hose Barb that's connected to the back of the gal pipe.

I use standard compression fittings for copper on all my guns. I slide some 6mm clear plastic tube over it and stick a compression olive over that, then I just screw it all up. It's air tight and I've never had a problem with it, even at 400psi. It's so much better then epoxying because I hate the idea of never being able to take it apart if I get a leak.

With compression, everything is threaded, everything is reversable.


UPDATE! The pistol is dead. I've made a completely polished 300psi+ meter long 8mm boomstick! I'll post it soon!
