Update on my project.Got some work done on it over the weekend. Corrected the size opening from the fire box to the smoker chamber (based on the Smoker Ration Calculator needed 32 sq in). You can see it in a picture below.
Cut the door opening in the fire box, mounted hinges, and trim.
Fabricated the air intake and welded in the hole where I cut out the propane gauge.
Redid the hinges and remounted the door on the smoker. Welded the handles on both (actually did this before the air intake).
Getting a little closer. Will be working on the cooking grill and wood burner grades hopefull after work this week to get it ready for the sandbaster and paint. Will post more as I work on it.
