The 20" is fine and will work. Often times too tall an exhaust results in your draft stalling because the heat cools and becomes heavy. I would come up one more inch on the fire grate.
I'm using a 4" inside diameter stack. My plenum hole on the inside of the cook chamber is 5 1/2" X 4 3/4". Im using 1" angle for my cooking grate track. Here's a pic of how the 1" angle will cover a portion of the hole. The tape measure is where the track will be. . Do you think the track will mess up my draft? I made the hole bigger than 4" thinking that would compensate for the rail being in the way.
yes....YES....definitely do this...(don't ask me how I know this ;) )
Looks nice. :) Tack you a piece across the short end temporarily to help keep the uprights from spreading.
Looks good. It will be stronger that way. U gona burn wood in it or charcoal?
