true, its a rough work, its intended to be hand thrown, mostly composed of pvc, a piston valve would work from the pressure plate, but i don't have any experience with those

Im sure most of you are familiar with the tornado impact grenade here http://www.youtube.com/watch?v=-KHvUaTdZhQ Ive always wanted to be able to find a decent build for a homemade grenade. A timer would be preferable but I haven't had any luck finding or coming up with a workable design. This is a r...

vortex blocks are pretty easy to make, a block of wood with a few holes drilled in it is all you need. oh plus a bb skirt partially covering the block to prevent jamming. Just a hand drill and drill bits really

A guy I airsofted with built it, theres no videos i'm aware of, built I'll see if I can get a drawing for you

I have actually seen a design similar to this one, though instead it used a Co2 cartridge and a nerf football from a launcher. It didnt' work because all that pressure blew the foam apart. They didn't have any intertia problems from the launch triggering the round but it was a relatively low speed (...

ah excuse me, i wasn't making a distinction between the battery powered valve and the mechanical one

Okay if i choose to use a sprinkler valve as opposed to a solenoid or otherwise. I would still prefer to have the safety of a disconnect from the trigger. With a modified sprinkler valve would a solenoid as opposed to a blowgun as the trigger defeat the purpose? Or instead would a simple valve in th...

I'm using it in a slightly different setup for my rocket launcher. I'm using this regulator http://www.ebay.com/itm/Aquarium-CO2-Simple-Regulator-Diffuser-Adjuster-moss-/270719015463?pt=LH_DefaultDomain_0&hash=item3f081c5a27 and then will have that pressurizing to about 125 psi or so a chamber of st...

yours would be preferable JSM but it won't fit US tanks, i'll find one that does though

edit: aw crap double post

perfect, just what I was looking for

inline vortex I take it?

and where did you get that air tank? Im looking to build something similar

and stock inner airsoft barrels are 6.08.

Another question, My regulator from the Co2 tank into the compression chamber needs to be inline if possible, which is why I'm trying not to use a Palmers stabilizer. My goal psi is between 75 and 100 if possible, but I can't seem to find any regulator that would work for that. Is there any reg out ...

*facepalm* didn't read the design of the cartridge close enough apparently.

I like the idea of the cartridge, but I will try to see if i can build one first before I commit to the design. How would I pull the piston back to release the air stored behind it? I considered the valveless design because of its simplicity. But it seems like it would waste quite a bit of air, and ...

I have a 1" solenoid now, i'm looking for a 1.5", and if i used the sprinkler valve i would modify it to use a blowgun so no it would be a mechanical trigger as opposed to an electrical one.
