Took a while to assemble all the parts but here it is. Only things different are i used an electrical pull box instead of a mailbox and i put a damper on it.
There is a ready-made knockout for that upper level hole.
12 hrs later and it is still smoking. I closed the damper down ti about a quarter open. Guess that AMPNS tray really works. I will open it up when it gets daylight and see how much of the tray has burned

Man that is some nasty stuff settling in the bottom of my mailbox. Stained my fingers brown and it doesn't come off.
I suspect that is what was turning the meat black when using the chip loader
Looks like the mailbox and heater hose is acting like some sort of filter.
Do you clean that mess out of your mailboxes?
