I'm a rookie at this art of smoking and won't even have my OJ Highland for another week. I've read and watched pretty much all of the info for the mods that need to be done so I know what i need to do to get this unit up to full potential. As far as the baffle plate, I have access to a metal fab shop and can get aluminum for very reasonable price or maybe free. I have read that aluminum is not as good of heat conductor as steel. I was thinking of fabricating one out of 1/8" or .080 aluminum. We don't stock any sheet metal but I can get it if need be. Have any of you tried this? If so, what was the outcome?
