A inexpencive and simple to make chamber for pneumatics

Unread postAuthor: sam_516 » Wed Jul 19, 2006 2:22 am

ok this is an inexpencive chamber for pneumatics, get a soda bottle and file the thread off it, then get teflon tape and put a thick layer over where the thread used to be, now get a nipple with a 3/4 inch female side an screw it into it, there you have it an inexpencive chamber.
p.s the bottles explode at around 130psi so do not exceed 110psi and if it does explode then you can not sue me for your loss of hearing caz i am warning you now BUILD AT YOU OWN RISK, ANYTHING UNDER HIGH PRESSURE IS DANGEROUS, IF YOU FEEL THE NEED TO BUILD THIS DESIGN I AM NOT LIABLE FOR ANY INJURY/DEATH THAT MAY BE CAUSED.

Lol nice "tutorial" and every better "paintjob" with that pink...

Not bad, I just use a bird feeder 2 liter adapter epoxied into 1" pipe, it's probably a better fit in 3/4" though, I just use tons of teflon and it seals good, any soda bottle works for mine, unmodified...

You way is easier though because it just fits in...

I've heard that you can just fit it into a 3/4" Coupler. Does anybody know the volume of a 20 oz in cubic inches?

I found another way to attach the bottle, I took apart a shampoo bottle and the housing for the pump fits inside 3/4" PVC with duct tape wrapped around it, the other end with threads was filed down and fits inside the neck of the bottle. I don't have any pics to explain it.

lol sputnick I was thinking the same thing
but wtf isn't this pretty much a useless topic and probaly kicking up an old one. A) this is common sense B) this is probably the most unsafest thing you could do C) why the heck cant we talk about safe firearms when we have people advising others to make bombs

i know it's old, but im new and so still need to go through old stuff, and felt the need to add my 2 cents.

It is unsafe, it can hold the pressure, but the walls are so thin that any rough handling will make it fail. If anything i would use one of those "chubby" bottles, because they are much thicker, only becauese they are more compact.

The only things pop bottles are good for are silencers, and holding pop.

C) Agreed! there are far worse things in the world than guns, and if we do not teach people safe gun ownership, we will only make it worse.

haha thanks man, im new here, but this already looks like a sweet site, im wondering howcome i've never heard of it before. Maybe next weekend i will post some pics of my marble gun, its pretty modest, not having a sprinkler valve ( not available ANYWHERE in ontario for some reason), so i ended up having to settle for a hose sprayer valve, which works alright and is very ergonomic. its also got a silencer, which actually works Very well and looks pro.

And while im talking of the site, How do you search just launchers? whatever i enter into the search bar leads to forum topics.
