Well as I said I found a way to build my smoke box for an offset, the thing worked ok I guess as it was but for some reason I had to make it an offset
heres the before pic
Hers the start of the new fire box
Here is the opening I cut in
here is the fire box I built to slide in and out , looks like it will hols about 1 bag 13.5 lbs of charcoal
I still need to build the hinges for the door on the smoke box and add some stuff like handles ect. but I went ahead and put some smoke in it tonight before I finished welding things up just in case it didnt perform and I must say I was pretty pleased even if it is about as ugly as they come !!
