Hi All,
Let me say thanks for all the help and suggestions i got from my post!
I would like to as everybodys opinion on chambers! for short distance such as 50-100 yards with a,small launcher (shooting tshirts) with co2 as source of air.whats the ideal chamber and barrel size combo? and with your suggestion how many psi will it take to get this?say if i have a 20oz bottle on and want to shoot 50 yards,every time. How many shot approx. will i get with this chamber, barrel combo . thanks for all your input on this matter.

with co2 as source of air

Using CO₂ as an air source could be difficult...

And why are you asking this? Does GGDT not work on your computer, or did you simply not read the Wiki before posting?

Hi,
To answer your question<=,not it will not run on my pc.or i would not be asking!And when i say 50yrds ever time i mean around that distance! i just want to make a tshirt launcher and have read all i can find cant run programs so i ask.if you have not looed IM NEW!! to this forum was not aware that i was to know everything already sorry. still learning site everyday. but some times when you mess with co2 you just want to ask a second opion.thats all.sorry for have had yopu waste your time to answer my question,oh yea thats what forums are for!!!people learning from people!!!

Hey..don't get bitter now..We're all here to learn and have fun.

It's really difficult to guestimate an ideal chamber size, especially when all options such as pressure used and desired max gasconsumption and barrellength are all left open.Not to mention another big factor: the valve.

People here don't mind questions, we do kinda dislike newbies asking questions for wich they could have found the answer themselves.

We should consider newbies don't know where to look, so we should tell them where to find the info, instead of BARKING where they should have found it.

I do not expect you to find the answer you need by yourself, so it was good you asked.
We need to know all the factors before we can answer.
In the mean while, read the wiki, button is in the top of the screen

K well, unlike my other spudfiles members i'll give you my take on your problem. Not putting them down, just gonna answer it. First off I gotta know where you live so i can assess how readily you can access co2. I live in the US so it's not that hard. I have used co2 in all of my pnuematic launchers and it is no problem. just be sure you have the tank stable and chained to something or atleast secure. make sure to use a proper regulator if you are using anything above paintball tanks. i personally use air compressor quick couplers on the end of my hose and on the launcher. it's cake.

af far as your launcher i would have to say that the size of the chamber is dependent on how much weight you want to carry around. If you're making a t shirt launcher, which i do have experience with, you are probably going to want to use a 3" barrel to comfortable fit a t shirt. as far as your valve i would use a 1.5" sprinkler valve. It is really the largest cost effective valve. you can usually pick one up for 50 - 60 bucks. as far as the chamber i'd go with a 3" diameter chamber probably 18 inches long.

I personally use a 1.5" irritol valve with an adjustable piston limiter so i can dial down the shots for short lobs instead of full blasts to the nosebleed section. Other than that, I hope you have the knowledge and know how to modify a sprinkler valve, which is found in the wiki and in the search engine. Other than that, all i realy have to say is solvent weld properly use pressure rated parts and if you didn't understand any of that take a hike.
