making a cloud, few questions

[super spuder]

hmm, long time since i have been on this site. Think its time to make a cloud. Just have a few quick questions. How long should the chamber be? going to be 3 inch diameter. How long should the barrel be? The barrel should be 6mm id right? See allot of people using brake line for barrels, anything else work good?

Brake lines work well, since they're already set with a nipple, so all you have to do is drill a hole and screw the brake line in.
I get my piping from hobby shops
3 Inch diameter chamber? Thats big....

[super spuder]

would 1.5 inch pipe work better? i dont know much about these things.

[elitesniper]

yes, the smaller the chamber the stronger it is.

I would even say 1.25in
The rule of bbmg is
larger chamber=more ammo, less velocity
longer barrel=faster velocity, less ROF

+1 to that.

If you're planning to use the cloud in an airsoft skirmish, i suggest having a smaller chamber and a longer barrel.

na, this is just going to be for shooting stuff at my house. Thanks for the help, guess i will be going to get some small pipe sometime soon. would a longer chamber educe velocity to?

[elitesniper]

yes, as it adds more volume to the chamber theres less power.

[super spuder]

well that makes sense, glad i didn't pick up all the 3 inch adapters and stuff today.

Do they sell 3'' pipe at your local homedepot?

[super spuder]

i get all my pipe from TSC... and yess they sell 3" pipe

i made my cloud out of 1.5" end cap, 1.5" male threaded and a 1.5" threaded end cap. Along with a brass barrel it works a treat, rips up cans, card anything!

heres a link to it:

This is understood, however, is there a good ratio to maximize both ROF and velocity, or is it just trial and error?
