thanks everyone for your help!

well, the chamber didnt blow up, but the connecting pipes did, the chamber is made of SCH. 80, so i wasnt worried about that, but the rest is regulare PVC

you should try a pneumatic valve one first. it might be easier

I was wondering about Oxy-acetylene. I had a really bad mistake with it (explosion). Mostly its used for welding torches. Anyone particulary have any knowledge about it, and maybe how to use it safely?

Thanks
