this may sound stupid nut on that tank how is the pin in the propane tank pushed dpwn so the propane is relased to the first ball_valve.

yes the cops will arrest you if you get caught but if you dont then go for it

The really coarse steel wool works great for electrical ignitors. Its cheap, and easy to get. Although you can order NiChrome wire on the internet. But its damn expensive, like $10 for 100 feet, and that wire is freakin thin.

Anyway, heres a site that has very good directions for making electrical ignitors. I use steel wool, but make them like she makes the ones using copper.

hmm, this bugs me, i see some people using ABS and some using PVC, im just starting out and I'm wodering which one is better or safer to use. can anyone give me some tips please? it would be greatly apreciated.

Me being an idiot,I was new to pneumatics and i used 2" abs and i got it up too 90 psi with no problems.

[SpudStuff]

yes you were being an idiot, but that dosn't answer the question. The answer is always use SCH 40 PVC on pnumatics. you CAN use ABS on combustions

that looks and reminds me of a mortar just by the way it is set up on that hill.

[spit_spud]

the last picture is it a pneumatic gun or just to add pressure? nice bazooka looks powerfull, try using eggs as ammo....

[pyrogeek]

You can use steel wool instead of NiChrome wire if you don't feel like scrapping a hair dryer.
And don't go egging their house...smear dog poo on their door knobs.

The propane meter has a special fitting on it that has a pin to push the valve down to open it. I have used them before, they are way way better than Bernz-O-Matic torch heads.
