I've only smoked meat in ready-make smokers, and even that not too many times.
I just moved into a new house with a build in grill. See the picture below. It's an Argentinian style grill designed for asado (beef ribs). The grate lifts and lowers by a pulley system with a handle on the side.
I don't know if there is some hack to transform the grill into a smoker, or whether you recommend starting from scratch.
If you think it can be "salvaged" into a smoker, I'd love to hear how you would set up the smoke as well.
Some details: it has a chimney, all the sides are brick, and the front is open. I could probably cut a piece of metal to close up the front... thanks in advance for the input.
