i made a fire extinguisher pnuematic, its in the unofficial pnuematics cannons. its called the la france pnuematic....the only problem i cam across was the thread was not standard, but a 1 inch male adapter screwed in pretty tight with 4 wraps of teflon tape....it doesnt leak at all

Hi, I am building a pb gun and I have a question.

1. I am trying to calculate the proper ratio, and trying to find what set up is the best.

I am using EVBEC v 1.2 at the moment and it is the calculater for combustions. Will it work the same for pnuematics? Will the ft/s be the same?

For example ...

thats not a pop-off, its a quick release

id say try it, i mean if you really want to destroy the camera....but try putting the camera in a clear bow, such as lexan (otterbox) its a brand of box that is crush proof, so you can pretty much run it over with a car...anyway, try that, that wasy you can reuse it over and over again. Be sure to ...

Yeah, I would buy a stun gun anyday, if I was that into spudding, but I only shoot <20 shoots a week.

I was wondering why some people use bbq ignitors instead of lantern sparkers. I want to hear your opinion with each....Here's mine:

Lantern sparker
-Good large spark
-Cheap
-Easy installation
-Never misfires
-Works for practically for ever
-Easy to use

BBQ ignitor
-Harder to mount and set-up ...

Well i FINALLY got my sdr-21 from the local hardware store so i got my golf ball barrel done. Ive been shooting it at 120 psi latly and it shoots so well. I shot a golfball through 2 peices of 3/4" chipboard nailed together. my combustion will shoot through one...

the spring has always been in it, but i fixed it, i found that the grease i was using was not thick enough. So i used some heavy duty hi-temp grease and it works perfect

i got mine to work, i used a super thick hi-temp bearing packing grease. and it works perfect now

im having the same problem, but i have a 3/4" watermaster. Im even using a aircompressor with a quick disconnect so the air is going in plently fast.

ok i modded my sprinkler vavle and all (orbit watermaster 3/4") And i installed it, but when i went to fill it up with air it just blows through the barrel and honks...So i disassembled it and lubed up the diaphram. still wont stop honking, it with occasionly seat and begin to fill up but its not ...

just a 1 inch threaded bushing kinded jammed in there, o and the bottle isnt really for perfomance at all, mainly for safety and looks.

Well this is my third spud gun. I aquired a fire extinguisher and i wanted to use it for the tank. The treads oin the tanks were metric but i screwed in a 1 inch male bushing and it seems to be ok. I modded a sprinkler valve for the first time which was a success. Everything went together ok and i ...

The higher the pressure the cooler the co2 is, so when it enters the chamber it will be so cold it might cause the tank to burst

ok do you guys not understand, hes not gonna want to send you "Plans" for this thing. Its simple, all it is chamber with the hose connected to it, so you fill the chamber, then hit the ignitor and it shoots, not that hard
