I'm a new member just checking in. I have been lurking for a while and soaking in as much as I can for my project. I've found more useful information here than any other source. Thank you all for the advice you have given others; it has also helped me. My project is an outdoor BBQ island. I plan on including an Argentine style grill, a smoker, and a pizza oven, all made of block and brick. Having a little trouble trying to determine proper dimensions and ratios for the smoker to have a good draw. Any advice on that issue would be appreciated.
