multi pump rifle

Unread postAuthor: EddT07 » Mon Aug 20, 2007 1:20 pm

Can someone show me a diagram on how to make a multi pump rifle that can shoot .177 bbs and pellets? I know alot of people get mad when a noob asks questions like these so if you can't or don't want to provide me with a diagram or plans can you at least recommend a good pump i could buy?


thx

Do you mean pump action, or "pump it up and shoot"? Then perhaps we can give you rough guidelines or help, but no spoon-feeding :wink:

You expect someone to give you a complete diagram of a multi-pump pneumatic rifle?

If you simply want a cannon that shoots .177 bbs, then you just need to build a simple pneumatic cannon with a .177 barrel. (read the wiki, look at the showcase, and the how-to sections) Then you can attach a bike pump. There. multi-pump.

the best pumps are home made pumps, just take apart a bike pump to get an idea of how they work, they are very simple. i dont know if you can find it or not (i didnt look) but there are pumps for river rafts and inflatable kayaks that are two way, meaning they pump of the up stroke and the down stroke. i took one apart and the way it works is the piston is hollow and has check valves in the piston rather than the hose. its complicated, but im sure if you look up two way hand pumps you will get a diagram.

as for the barrel, you can go to the hobby shop near you and get some tubing that will ft pellets/bb's. also i have found that easton aluminum arrow shafts work well, but you have to shoot .22 caliber pellets and even then its a little loose.

for a valve i would suggest a 1/4 or 3/8 inch QEV, they are easy to get on ebay or off mcmaster.

im pretty sure you mean a "pump it and shoot it" rather than pump action. i dont think that anyone here has made a pump action bb gun.

what ever you do, good luck.

"physics, gravity, and law enforcement are the only things that prevent me from operating at my full potential" - not sure, but i like the quote

you know you are not an engineer if you have to remind yourself "left loosy righty tighty"
