A barrel bigger than 3/16" ID is too big, just to give you an example of a tiny barrel.

just mod a super soaker. put a bicycle tube valve for a new pump.

it has a quick release ball valve using a spring.

A fully modded blowgun has decent flow, it would work in conjunction with an airsoft barrel. I may try this someday.

good choice a ball valve would work much better i used a blowgun on a mini that shot airsoft and chunks of potatoe and it did not have the effect i desired (more than 100 ft but if that works for you then get a blowgun) but it did hurt like crazy if you pumped it up to 160psi and got shot with it.....thats in theory of course because everyone knows never to shoot at people :twisted:

100ft, mini, thats pretty good, I bet you could make a coaxle, and using a rubber schrader as an refill, actuator, even a bumper for pistons

Holy Crud this forum gets no traffic, what the heck is a "Blow Gun Valve"??

And isn't a ball valve a little too slow for a mini? Has anyone got any experience doing this?

Build a tiny coaxial with a schraeder as both fill and trigger valve perhaps?

In fact here's a thought. Buy a cheap plastic double action cap gun, you can find them all over e-bay and similar.

Hack the poor thing apart so that you keep the grip, trigger group, hammer and some of the barrel but remove the receiver. Replace this with a schraeder valved co-axial, so that the hammer when it falls forward hits the valve core.

Bodge the whole lot together with glue, duct tape, bondo, and spit.

Voila cool(ish) looking mini co-axial pneumatic. If you built this with a decent chamber which could actually take a reasonable pressure you could probably get all this in one of those break opening revolvers, and put the chamber where the cylinder would usually be.

*off to toy shop now*

hey SPG, I see you're missing spudtech too :wink:

I think you had proposed the idea above when you had seen my mini-coaxial too.
