Pressures generated during combustion

What kind of pressure is generated when propane combusts in an 1800 cc chamber? Has anyone ever had a chamber fail explosively using propane? just curious what im getting into.

cool, I'll give it a try. I think my problem was that i might have tried to clean up the threads a little too agressively... I'll try the tape, thanks a lot.

leaky end cap

i'm using a threaded end cap on my metered propane gun. It is leaking pressure when i dump the propane into the chamber. Tightening the cap helps, but doesnt solve the problem. Would a new cap possibly fix this issue? or should I start over and use a ball valve instead. I've seen lots of propane gun...

Camera Flash Trigger

I'm in the process of modyifying an old camera to make my self a camera flash ignitor. First off... am i wasting my time? is this method too complex for the quality of the end result? Second... what is the best way to wire it? I have thouroughly studied the 'spud-wiki' section of camera flash ignito...
