Hi all,

I've been looking through the forums at posts about portable bbmg's and ive decided to make a portable BBMG that is still relatively effective.

I came up with this it is ghetto but it works quite well.

THe cloud chamber is a pack of cake decoration balls and the barrel is a straw.THe air chamber is a chamber i was going to use for a pneumatic but i thought about making a bbmg.A blowgun serves as the valve.

THis is me firing at my "special box"

In this video its shooting at a coke can and every ding you here is a hit.

i will upload Pictures of Damage etc soon.

This video is target test from 5 metres away.I was surprised at the accuracy.(the camera is on zoom).

THe gun is about 55 centimetres long.

Interesting design... looks like a lot of fun.

But the fittings on that air chamber look like super DWV to me... what type are they?

That is awesome!!! I agree with rmich, that is a very interesting design... At first it appeared to be a combination of a co-axial and a cloud, but then I saw the little bottle on the front.... I wish I had a blowgun laying around!! Do you guys know of anything ghetto I can subsitite?

ball valve

Interesting yet effective Design u have there ,

Any idea how many BB's per second ?

About 25-35 approx.You cant see them until they hit the target.

I'm not sure if its DWV but it works well.THere is a small leak which im epoxying up tonight.In those videos i put the gun up to 65 psi.

edit-RMich, its bostik pvc pressure cement.(if thats DWV then there you go.)

ball valve

Unfortunately, I am fresh out of those. LOL, aerosol valve!?!? I am really tempted to try it, but I don't want gunk all over me.

try it,if you get gunk all over you but it works know tha it works and be happy,If it doesnt work and you get gunk all over you still be happy.

I knbow its getto but you could have made the chamber twice as long, had the blowgun sticking out vertically from the back end and had an effective bullpup

I don't really understand how it could be a bullpup.Explain.

i meant something like this:

right,well i was contemplating something like that but i never thought it was entirely neccessary.better accuracy.

like that you'll have a bigger chamber (harder to pump but it will last longer) and a longer barrel (more efficient & higher velocity) without increasing the overall dimensions.

Well, I got the valve off of a chain lube can, and luckily, no mess!!
But, the question is, now what?!? It is pretty much the same diameter of a sch-40 3/4 inch pvc pipe, (within about 1/24, or something) which won't allow me to put it inside... I probably could cut the valve out of its casing with a dremel, but I don't know if that would render it useless, or what! I am not sure what to do, should maybe I should try putting it inside a fitting, and use some epoxy?



Here is the valve with the straws on it.

The top without the nozzle



Side view



Anyways, should I try to cut out the center and thread it like a shrader? Or, at least epoxy it in?

As far as I know, it can at least take 70+psi, which is good. My securing job, may be difficult to live up to this. Anyone with more ghetto experience than me have any suggestions?


EDIT: ANYONE HERE!?!?!?!?

Sorry to double post, but nobody seems to notice. Is anyone HERE? Plz read my above post I want some advice!
