look it up buddy, there are not many posts here about building a stirrup pump, your best bet would be to try elsewhere ... say google...

What Sputnick is trying to say is, you might want to try Google if you don't find the info you need on SpudFiles.
And on that note, Welcome to SpudFiles.

They pump to a higher pressure, but limit the volume to less.

There are actually quite a few. Several I recall quite well.

daniel323,

Just search the forum, try the how-to section and pneumatic cannon discussion section when searching. Try searching 'how to stirrup' and then click the circle underneath saying 'search for all terms'.

Search 'Search topic title and message text' and display as 'topics'.

Either search the whole forum, or narrow it down. If you tick the circle 'search for all terms', it will only display results that include all the terms you typed in. So try things like 'stirrup pump' 'how to pump' etc and hopefully it will bring up how-to's on pumps and compressors etc.

like what is the handle hooked up to? hubb017

Hubb · Fri Feb 06, 2009 5:34 pm

The handle is hooked to a piston that goes inside the tube. As you lift up, it allows air to enter through the piston (which is a check valve of some sort). As you push down, it forces this air out the exhaust, which enters into the chamber of whatever you intend on filling.

It's basically a bike tire pump.

ok its all starting to come together just not fully yet but i think i have a pretty good idea

daniel323 · Fri Feb 06, 2009 5:41 pm

so in this there are 2 check valves as maggotman said one is hooked up to the handle and where is the other one and can you buy these

sorry i might seem annoying but im new here and im only 14
thanks

1) what did I miss
2) please don't double post, some people don't like that

daniel323 · Fri Feb 06, 2009 5:46 pm

sorry ok i wont double post but how many check valves do you need

i dont know if this is right but by what you have said this is what i think correct me if im wrong

the handle is hooked up to a small pipe and that is hooked up to a check valve now im lost haha
