I am building a RF smoker and I am putting in a pipe burner arrangement for heat. I have seen all sorts of videos and posts on the internet about DIY burners. What I am needing to do will require me to DIY it so that is my plan. The bottom line question is this - Which puts out more BTU... a drilled burner with small, closely situated holes OR one that has the slits 1" apart from each other the length of the pipe? Does anyone know this info? Everyone has chosen their styles, as near as I can tell, because they have a drill press or not, a band saw or not. I got both and I am looking for a more technical approach. I figure I will build one of each and try it out just for giggles since they are exactly the same with the exception of drill or slit if nobody has input. I guess I will then have that answer for everyone, huh? Somebody has to be the first.
