So in a cloud I made yesterday, the airsofts just start spinning around and stacking into the pipe around the barrel. The only way I could get it to work well was put only about 15 BBs in the cloud chamber. Any good way to get a cloud to feed better? Possibly a diagram?
Thanks in advance!

Where does the breech fall in the chamber?

Not sure I know what you mean.. maybe I was using the term "cloud" wrong?

Sorry, I mean where in your chamber does the barrel start?

I have about a 1.5 foot piece of 1/2" PVC with bb's in it, the barrel is inserted about six inches into it, but the end has tape around it flush to keep the bb's for jamming in the space around it. On the other end, I have an end cap with blow gun mounted in it.
hope that was helpful.

Sounds like your cloud chamber is too narrow to let the BBs move around enough. In a cloud, the BBs need room to move. In your gun, the chamber is too small so the BBs jam. I would use a bigger piece of pipe for the chamber. You also said it works when you only put a small amount of BBs, further reinforcing my theory that the BBs need more room for agitation.

Ok. What size and length would you recommend? By the way - I'm shooting at about 145 psi if it matters. I originally tried with a two inch pipe, and none would get sucked out the barrel.

Maybe 1'' could work? 3/4'' is a possibility too.

Ok awesome .. ill update with results from both of those as soon as I can hook them up, so maybe tomorrow afternoon.
