So some might think this is off the wall but since Im just getting started in the smoke and que world I am just seeking advice and pointers. One of the things I have been noticing when I smoke or just do a burn in my smoker to learn its odd points and the biggest one I see is the thin metal...ugh so much heat loss!! My idea is to take a welders blanket and literally bolt it to the top half of my main chamber all the way around. It would be a lot like just draping it over the thing and I am sure I could at least make it look good(wife and grandma are seamstresses). If anyone has experience doing something similar or any other suggestions would be helpful. Thanks to everyone!!
