Detail drawings are plans that a machinist would use to fabricate the metal parts. These plans show in standard drawing format the burner designs that "Gas Burners" by Michael Porter book lays out so well in words. The plans are not meant to replace the book, just present another way of looking at the construction. The book is still needed to understand the many fabrication techniques, parts list, and assembly instructions. BCS Drawings - 1/2" Burner
