Looks great. I like all the home done craftsmanship. Also the spring handles on the fire box vents are a nice touch IMO. One thought, I build a similar horizontal for my dad not to long ago. He designed it with tuning plates and stack on either end. Soon we are going to cut off and fill the stack opposite from the fire box and make it a dedicated reverse flow since that is how he cooks with it. We are also talking about making a trough in the tuning plates to drain the grease. Based on our experience that's where we have decided to go. We also have realized the need for more than 2 air intake vents on ours. Overall congrats and looks great. Ton of hard work. Let us know how she cooks.
