I'm getting good at controlling the temp on my Brinkman Gourmet. But really, all that means is I know how much charcoal to light, and how much unlit to leave in it. I would like to be able to put more coal in it so I don't have to add more later. But, with no intake flow control, the coals would all light up, and my smoker would be a blast furnace. Fabricating a damper would be no problem for me. I'm just wondering before I do the work if it's worth it. Has anyone done this? Was it worthwhile? If you did that, did you also install an adjustable vent in the dome? I personally don't think it's needed in the dome, but I'd like to know if anyone did, and what they think. BTW.... The gourmet has the coal pan with cuts in it to breath, and it sits in another pan that has one big hole in the bottom to breath. I also installed an elevated charcoal grid in the pan. Thanks!
