Another fine use for bottles. As an airtank!

This actually isn't too bad. All you have to do is to put a tire stem into the bottle and glue it all up. I hooked one up to a hose handle and it pretty well after making everything fairly airtight. With a 24 oz. Mt. Dew bottle...I could get around...oh...50-60ish with one BB weight Stefans and a 6 in copper barrel. This is a fairly good airtank, and I'm sure a 2 ltr. one would work much better. Cheap and effective... Try it out.

Feet? or shots?
Awesome.

[robo7fish]

Sorry. I meant to say feet. And I could probably get better if my Stefans weren't so skinny.

I was thinking of the same thing two days ago when I was converting my super soaker into a nerf gun. The supersoakers air storage thing is broken so i tried using a Aquafina water bottle for experimenting but I couldn't keep it airtight. I was thinking about using a tuppaware. Not the square kind, but the pitcher kind that you put lemonade in.

Do you know what PSI you're using? Standard injection-mold plastic soda bottles hold quite alot of pressure. You can bring it up to somewhere around 100 PSI with a Mountain Dew bottle. How's the hose handle working out? I've had some bad experiences with leaks.

[robo7fish]

Wow, I didn't know they could hold that much pressure.

The hose handle isn't working too well. The very front of leaks, and my Stefans aren't fat enough to sufficently stop the unwanted airflow.

Actually a standard pop bottle can hold 175psi because its made of PET (i cant remember what it stands for)

Still awesome.
I wouldn't mind knowing how many shots you get off.



100/175psi? whoa...

[Dan Wask]

Its actually 125 psi for it to blow for a little 8 oz bottle. Believe me. I have the scar to prove it.

ok, well i think im thinking of a 591mL, srry, im metric, i dunno how many ounces that is

[robo7fish]

I'm only able to get off about... oh.. 6 shots a min..Terrible ROF. One shot wastes all the air, with a bigger bottle I could probably conserve an amount of the air.

Anyways, the gun would REALLY be improved if that dang handle was replaced with something better. You're screwing the bottle directly onto the hose handle?

1.Yeah.
2.Hmm... there's got to be a way to regulate that.
3.Good idea.

I agree, at least a better hose handle, and those bottles fit directly into the hose handle.
