really nice compact gun

since he wants to fire semi auto, pumping every time like on the PPK, is not an option... you could make a project bo with some batteries wired both parralels and series, you'd get twice the voltage and twice the current with four bateries....think about that.in that case your little 12V compressor...

Hello , for my next spudgun (my first pneumatic one) i need a way to fill the chamber while being in forest (im doing spudgun secretly and i cant fire in my garden ^^). so i was thinking about of one these cheap portable compressor but i dont think i will be able to fill a chamber at 200 psi more th...

You can, just make a project box...you can put the compressor in a back bag. with the hose directly connected to your sniper. Bolt design is much easer with copper....pvc in france is weak, trust me....i'm french too mhhh the compressor is too big to put it in a project box , if it is to heavy i wo...

realy awsome , could post picts of your entire gun ?

cya

That's nice , good job

Ah, an onboard compressor. It will be rather heavy. You could perhaps purchase an air compressor motor and wire it to a portable battery system. Same weight but quicker. i know... :/ i will see when i will buy it , if it's too munch heavy i wont take it onboard , but i would really like to have a a...

on board 12v air compressor 200 psi

say me what you think

ok thanks you all so if i do a basic gun like that : chamber => modified orbit valve => barrel with a 180 psi compressor connected on the chamber it would work ? i gonna do some researsh on the forum about the best C:B ratio beceause i dont know for pneumatics... with the hope i can find these kind ...

schmanman wrote:oh, sorry. had I known you were from France, I would not have pointed that out.

yes , I think 180-200 psi would be enough.

are you planning on using copper for the barrel and air chambers?

Dont worry

Copper why not PVC as usual ?

schmanman wrote:pressson? do you mean pressure? at those pressures, go with a steel piston valve. although, If this is your first cannon, a ball valve may be better.

sorry for my english... im french ^^

does 180 psi would be enought ?

Hello, since it epears to be the best way to make a powerfull sniper im maybe going to make one , my goal is to shot about 250 yards away (with the cannon at 45°) and to be the mots inexpensive... so i ask for advices about the chamber and cannon size since i dont know at all about pneumatics. to ge...

Thanks you all for your help , im posting a new post in the pneumatic section so that all pneumatic maniac could see it

Hello , Im just trying to make a good marble sniper and i want it to be the best possible... i plan to make it with a cannon of 1,5 cm of diameter with a height of 1 M but if i want a ratio of ~0.8:1 i need the chamber to be something like 2 cm of radius and around 10 cm of height , that's very litt...
