This is my 1st post/thread, I hope I don't appear too stupid and that someone can help. I have an old stainless steel grill with 1 good burner tube left. I plan on taking off the cover, cutting the box level all the way around and building a 2' x 20" x 2' wooden smoking box to affix to the base of the grill. The heat from the one burner on high topped out at 420* and on low, 290*. I figure that those will drop when I add a much larger "smoker box" than the cover that is on it now. When I affix a wooden box to the grill itself, what kind of fire barrier can I put between the wood and the grill so I don't burn the house down? I am contemplating spacing an aluminum flashing in between air pockets?!?
Has anyone contemplated something like this? Instead of buying electric burners or creating an offset smoker i would like to try this heat source first.
Any and all comments welcome.
Thanks for your time....
