I finished the tuning plates I have been thinking about for several years. Wasn't that hard and I didn't even need to hire a welder. I got rushed into a big cook job for church before I could take a photo so I will post one tomorrow. I am cooking 6 boston butts today and 4 more tomorrow. I have some playing an learning to do but I can tell a significant difference in how that thing cooks now. I always hear a sizzle from the fat dripping onto the plates. I have to play with it and tune it more, but WOW!...my temps are really close to each other now! I keep thinking something is wrong. The smell is also a bit different...very pleasant. I know that is from the "sizzle effect". The plates are 1/4" thick steel and are about 3" below the grate level. I may still put in an elbow to get the exhaust lower. Don't know. Will post more tomorrow with Qview!
