€15 high power pneumatic pistol

Unread postAuthor: alwinovich » Sat Jan 10, 2009 3:01 pm

my goal was to make a pneumatic pellet pistol
1for under €30 that was
2easy to operate
3looked clean
4was accurate and above all
5could easily fire through cardboard and soda cans!

so did i succeed?

1cost gun
blowgun €4.95
valve €5.50
8mmOD barrel €2.70/meter
that's €13.15

2 to operate
connect pump
pump it up
put a projectile in the barrel
shove it down the barrel
this can all be don in less then 30 seconds

3decide for yourself

4 at 5 meters i get a 3" without sights, haven't put any on

5 at 200 psi, less then half the max power, it goes through 2 soda cans or 3 sheets of cardboard

sorry for any bad grammar, i'm 13 and dutch

it uses the space inside a blowgun between the inlet and the valve as chamber
it have got it to +- 470 psi without leaks, i know it can go higher but my pump only goes so far :wink:
it has a 5.7mmID barrel (just a little bigger then 0.22") glued in the outlet of the blowgun
so .22 gamo long distance and pro magnum fit perfectly in it
I use a SKS Suspensioneer shock pump with a scale of 0-360 psi to pump it up(although it can go to >450)

some firing

the whole charging, loading and firing sequence

lead pellets >100, best at 200-300
spitballs 30-150 best at 100, starts unfolding at >200
