I recently picked up an original OKJ charcoal grill. It is a 20 x 36 1/2 unit and HEAVY AS HELL!! My one complaint is its only a charcoal grill. So I plan to mod it. Couple questions as I go this route with my options. #1 Do I convert to pellet? I was really wanting to go this route until I tasted my friends Traeger last month. Actually 3 of my friends now and it really doesn't do anything for me compared to my Old Country stick burner flavor. Which comes up to my next option. #2 Do I go standard stick and have a firebox welded on? If I do that, do I go standard flow or reverse flow? #3 Do I go with a firebox behind it and have the inlet in the center? I have heard this is a problem with grease getting into the firebox when you go this route. If I go stick, Does it matter the size of firebox? I have access to a OKJ 16 inch bbq charcoal grill I was thinking about having it welded onto it. I go to competitions all of the time and I see these huge smokers with really small fireboxes powering them. As long as the convection moves, I think I would be fine. I would just need to have the side door welded shut. But my buddy had a unique idea. He said to have the small 16 inch bbq turned firebox welded to just the door. He thinks it would be unique for some options. I cannot think of any options but he will let me know when he thinks of one. But a unit that has the whole firebox swing open is rather unique.
