My blog has come up in Google a few times for people searching "Gas Bottle Fire". Presumably because of this post . If anyone would like to know how I made this one just holler and i'll get some instructions together. I have used it for years now.

Just going through some archives. This pic is a fire box I made from an old 9kg gas bottle. This day it was heating water wet-back style for the pool you can see on the left.
Car wheels are always good...

...and sometimes you just want to burn stuff .
