Have you had any luck? I had originally tried just using a elevated grease pan with a drain but ran into a few issues. the addition of the small lower deflector and the lack of holes on the large deflector near the grease drain seems to be in the right direction, but still tinkering with it. The main thing to me is to be able to get the grease/animal fats out of the grill, no grease build up or puddles of animal fats limits or greatly reduces the chance of a fire. I think animal fats can ignite around 350-375. The grease catch pan that I use is a 20" round pan with a 3/4" pipe cut in half long ways welded to the bottom edge of the pan that extends outside the bullseye.
