So Im putting together my first brew sculpture and I have NO idea what to do when it comes to burners. I have been looking at the Banjo Burners but Im so lost when it comes to low and high pressure. What is the difference? If I want to run two burners off of a propane tank (not at the same time) What kind of Burner do i need. Also noticed something about drilling an orifice? Any help would be greatly appreciated.
