I am getting the hang of getting some consistant temps in my NBBD!!! So excited about that. How ever i have about 80* to 100* diference between the area near my fire box and the exit vent. What i have been reading seems to suggest that I should get a baffel for it to help narrow that difference. Is this the correct consensus? If so what is the best way to set it up? make one? buy one? And if you have pics that is even better as I am more of a visual person. Thanks in advance for the help.
