thanks for the thoughts
I am going to use charderheads idea. But instead of bricks, i am just going to try using a doubled up foil pan and just lay the grate right on that, the pans I have a plenty strong enough. If it wont hold the weight, then I can use bricks to support it.
I dont want to lay anything right on the coals or the charcoal pan, it might screw the airflow up
Ring of fire I will try one day, but not for this cook
