Real Pea Shooter.

[LucyInTheSky]

I made this today out of parts I had lying around in the garage. Its a very basic mini pnumatic triggered by a 1/2" Ball Valve. Iv not fired it yet, because I am not aloud to shoot my spudguns until sunday because I got detension, but have pressureised it to 140psi which only takes 3 seconds.
The main set-up of this is:

Chamber: 15cm x 1.3cm (ID) 19.90cm^3
Barrel: 26cm x 0.8cm (ID) 13.06cm^3
C:B: 1.52:1
Trigger: 1/2" Ball Valve
GGDT: With a 1/4gram BB or Pea.
-381ft/s
-1.2ft*lb

Nice! I like the quality metal construction,the simplicity,and the cleaness.How long is the barrel? Try shooting the front of darts,the pointy part you unscrew.

[LucyInTheSky]

the barrel is 26cm long.

hey thats pretty cool, pump it to 300 psi with a shock bike pump.

That could be quite mennecing.

[Benny]

thats the whole god damn point!

[LucyInTheSky]

how much are shok bike pumps? do they take long to pump thing up?

[Benny]

they are 20-50 bucks australian, they are only good for small guns tho.

I have a bike pump at the moment that can only pump up to 50 psi,you can't pysically pump past that.

20 Australian is $14.83 US
50 Australian is $37.07 US

I get good bicycle pumps at a flea market for like $5 US, and by good I mean like Spring Return Foot Pumps with a gauge....

Well I tested it today and its... ok. It shoots about 150m and flys freakishly fast, but its lacking in the power department, I think is because of the 7mm bore being so small. The most I could do was shoot a screw through cardbord.
But still shooting is very fun since it only takes 5seconds to get to 160psi, and you can get 15 shots out of one spud.
Over all I would say its a very good mini-pneumatic.
