More than one shot

Unread postAuthor: money434 » Tue Jan 30, 2007 8:03 pm

Hi everybody, I'm a newbie in pneumatics, and I was wondering if anybody has a good way of getting more than one shot before I have to refil my chamber. Since I joined the forum, I've been looking for plans, but most of them said that I would need to have an air compressor conected to the gun. I only want a BB gun that shots at at least 350 fps.
Thanks

do you have a lathe or a machine shop at hand?

your best bet would be a hammer valve...and a big chamber.

other than that i dunno.
and welcome to the forums!

Use a large chamber, a low flow manual main valve, and constriction before the valve. <a href="http://www.spudfiles.com/forums/viewtopic.php?t=5415&">This </a> might help with ideas.

Thanks for the answers. About the sprinkler valve, I'm having trouble finding one in my country. How does a gun that has a sprinkler valve works?

You need to seperate the link from other text to have it work. ^

money434, go to the How-To's and click on the Sticky: How To Mod a Sprinkler Valve, or go to the Spud Wiki and look around there.

I'm from Brasil. All the sprinkler valves I found were from outside the country, so the price would be the valve's+about 15 USD for the shiping+a price for the product to enter the coutry(wich is +- the price of the valve).

If you want multiple shots, you wouldn't use a piston valve because it dumps TOO MUCH air. Read the oringinal post.
