Real Pea Shooter.

Unread postAuthor: LucyInTheSky » Fri Jun 16, 2006 3:57 pm

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. :D

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.
