Can anyone remember the name of that forum that was for machined pcps?

O cool Nerang is about 20 mins away from me

well i had a look at the arrows for ya BOOM, this is what they say on the shaft- AL 7001 - T6 2114 redzone by A.A.T. probably not much help.

Edit- o yeh the sight is made out of the same rod as the silencer and i just crossed some red fishing line at the front

nah the paint is just regular water based white house paint. The arrow though i have no idea, its an aluminum one. It used to have some writing on it but that seems to have disappeared :o i'll look for some tomorrow and tell ya what it says. as for the silencer it works enough to reduce the echo it ...

This is eggbert the 1/2 inch piston valved gun. it has a barrel diameter of 7.1mm (an arrow shaft) and is made of brass and galvanized steel. It has a spring behind the piston and the piston is made out of the white plastic tube from dry fire extinguishers, the sealing face is some clear vinyl tube ...

hey guys just need a quick response here, i found this on ebay. apparently its half inch. http://cgi.ebay.com.au/Valve-Solenoid-type-12-volt-1000-PSI-for-air_W0QQitemZ370221704151QQcmdZViewItemQQptZLH_DefaultDomain_15?hash=item5632eee3d7&_trksid=p3286.c0.m14&_trkparms=65:1|66:2|39:1|240:1318|301:0|2...

hey fellas. for my second gun i wanted to make it so i could get 2-3 shots out of 1 fill. but here is where my problem lies I don't want to have the old spring behind the piston. I would rather have the chamber with a b valve on it. Here is the design, but i have a few questions, will the piston sti...

its not really worth it mate, unless you use the air pumps that people with large fish breeding set ups have which run to multiples of 8+ tanks. those get pricey so you would get a better price and performance from a fridge compressor.

Hey guys this is my first ever attempt at making anything like this. umm well the diameter of the barrel is around 10mmish, air tank is a poly riser cant remember diamteter. basically its just a super basic ball valve gun. i can pump it up to about 100 psi in a few seconds with that cheap ciggy comp...
