well thats three so far
do u get your pvc from bunnings?

There's alot more, shud_be_rite, kirk, some other guy in Auckland, and a few others who have dropped in then out.

[battlemonkey]

well i have never seen anyone else in H town with a spudgun. Although a few people have seen me, firing spuds over the waikato river, shooting of paintballs verticaly at local parks. once i even loaded a 2in ball bearing into my old combustion and shot it straight up (had to come back with spade to get it out)

[ammosmoke]

JSR, would you happen to know how long it takes for a QEV to reset? Is it instant? I have never worked with one before, so I don't know...

[jackssmirkingrevenge]

No idea, but I presume it depends on the pressure and flow you're putting into it. I'm sure Hotwired will know

[ammosmoke]

I would be putting about 120psi into it. But I was planning on using a
1/4" one of them on an airsoft gun. The one in my sig. It will have a 4" 2" dia sch40 firing chamber, which is connected with a checkvalve to an 8" long 3" dia reserve chamber for semi-auto action. I will prob use 1/4" tube or smaller to connect the two tanks to limit lost air. However, that is why I was thinking of using this strange shutoff valve for a checkvalve. It is automatically supposed to close when a hose ruptures. This would increase efficiency, but I am not sure how the valve resets. I made a post about it, but nobody to my knowledge has replied yet....

I am thinking the stupid title is keeping me from getting any replies lol...

I had missed that topic. Presumably that FS valve resets when flow is restored, which in your case will be impossible considering the flow is meant to be going through it. I would think that a 1/4" QEV would reset pretty quickly though, removing the need for a check valve.

[ammosmoke]

Yes, but I don't want it to fricken, empty the whole reserve tank in one shot!!! Or all my ammo for that matter... The check valve just allowed for me to keep some sort of control over how much air was flowing through between the two tanks... Idk, maybe it doesn't matter as long as there is a small diameter pipe, like 1/8" nipple or something... What do you think, almighty airsoft genious?

EDIT: Oops, I think its supposed to be genius...

[jackssmirkingrevenge]

Then I take it you're not fitting a breech mechanism that blocks off the magazine on firing? Why not fit a paddle like mark used in his marble gun.

Restricting the flow to the QEV will only make it reseal slower. Why not focus on your pilot valve, you need one that will open briefly enough to pilot the valve but close up immediately after.

Back to the subject of this thread, I've decided to revisit this project. Given the velocities I got from a blowgun, I always wondered what the power would be like with a more efficient valve. In that regard, I've grafted the breech to my nailgun with the hammer piston blocked off and air channeling through a 6mm tube into the breech. Expect some results tomorrow.

edit: It's done, but I'll allow the epoxy to harden fully so testing's due when I come back from work

[Mateo]

hey i have a nail gun exactly like that but how did you get the breech off? ive been trying to make something like that.

[jackssmirkingrevenge]

easy

[TechnoMancer]

its meant to be Allen key!!!!

[jackssmirkingrevenge]

That's what I call them, but in the states it's usually a "hex key".

[TechnoMancer]

i think some guy called allen had something to do with the type of screw/bolt head that is used for them. hex is an alternate name for the six sided shape in the head.

"Allen wrench" was originally a trademark of the Allen Manufacturing Company in Hartford, Connecticut, taken out in 1943.
