As the inventor and developer of said BB you need to change a few things.
1) criss-cross pattern on the grate so you can develop a coal base. I just used a cheap cooking grate on top of the charcoal grate.
2) I'd do a basket (add side walls)
3) I went 5" off the bottom because you can go forever without emptying.
4) I went with four 3/4" intakes so it gets enough air to start and you can close them off as needed.
5) Definitely go skinnier splits and less wood.
When I'm done cooking it gets closed off tight because the partial burnt will start with just getting hit with a HF weed burner for 30 seconds...up and cooking in less than 5 minutes everytime. When flaming starts then I'll add a couple of skinny's on top. It just doesn't take much wood.
Using mine now for almost 2 years there's a learning curve and it takes a bit to really get the hang of it but you'll turn out some amazing food if you keep the fire in check.
