Thanks, RW. Drain rack info - the rack is removable, it just sits on the lip as does the burner rack. I'm pretty sure it's just 1/2" angle that I heated and bent to fit the lip. I've never had any issues knocking it off. If I were to build another, I would use smaller separated iron - like 1/2" flat. My is 1" not-flat (?) - some times those small shrimp critters and craw dads fall through!
Here's some pictures I snapped of it.

Above picture, I'm cocking it up to show how it sits down on the lip. There is not a gap when it is sitting down.
Burner rack - same thing, just sits on and wedges. Grinding this one out, the way I did it was a pain in the ass to get everything just perfect, but it's helll for stout. I was initially concerned that with the heat cranked up, it would get hot enough to bend the mounth under the weight of a turkey cooker full of water - you know how heavy that is - but have had no issues. The expanded metal get's cherry red, but not the bracket.
Let me know if you have any other questions.
