fire extinguisher handle

Unread postAuthor: spudthug » Mon Apr 09, 2007 6:15 am

has anyone ever tried to use a fire extinguisher handle as a port??or even a main valve???it seems like it would be good flow if u took out a few parts....all u would ahve to do is take the hose off of the front and then take the nozzel off....it seems it would be like an automatic 1/2 ball valve...if i get bored shooting my new gun today ill try it and see how much flow i get compared to a ball valve....and it is in a conveinient handle like trigger and it could be used for over under pneumatics because it is a 90 degree hole through it..what do u guys think

I used one as a main valve for a small caliber pneumatic. I designed it to work just like a pellet gun. I didn't finish it because I needed a lot more pressure to be using a "hammer valve" setup. As a pilot valve it would probably work better than a blow gun, especially if you have a lot of pilot air to exhaust.

you cant, once you open a FE valve it wont seal up properly again. maybe if you planed to shoot it within the next 10 seconds, but other than that, no. maybe yours will seal, but mine never did, i tryed it several times.

Brian the Brain used a fire extinguisher and the valve on his marble machine gun. You can see this gun <a href="http://www.spudfiles.com/forums/viewtopic.php?t=3313&">here</a>/ Apparently, the valve was pretty high flow, and allowed him to do some serious damage with that gun...

If CO2 fire extinguishers are charged to 800-1000PSI, then could I simply clamp the end of the black hose to a fitting and then connect the fitting to a steel barrel? Though the valve is slow, it gives a lot of CO2 in comparison to the pressure in a normal chamber.
I know that this would be a ridiculusly costly way to make a gun (you'd need to buy a new FE for each shot), but I'm just curious.
