pnumatic preformance

Unread postAuthor: )DEMON( » Mon Apr 24, 2006 1:35 pm

ok,so if your barrel ,valve and chamber were all linked together with silicon pipe about 9mm thick on the inside would it affect the preformance of the gun in any way?

By "silicon pipe" I assume you mean silicon rubber tubing.
This is typicaly a translucent, soft rubber, and slightly tacky.

If correct... that stuff isn't really made to take much pressure (although it's probably fine for our use - just don't blame me if it pops), and with an inner diameter of only 9mm, it'll affect preformance a fair amount.
You can model it with the GGDT by limmiting valve flow to a Cv of ~2.16

What other ways can you link your system,without using pvc parts.I would think that using thicker tube will mean better preformance ,right?

How can i improve my chamber?
