I seem to answer this question once or twice a month, so I asked the powers that be to pin this for us. If I'm not clear, ask the question.   I like blown burners, they are brute force and dirt simple (just like me), so if you are looking for venturi advice, you must needs go elsewhere.   SAFETY WARNING Building and operating a burner like the one described below is dangerous. It can burn you (since hot is what it does). It can create explosions of various sizes. You are responsible
