DIY Ammo box propane firepit

[Clb]

Yes, but takes away from my use. Often times its sunk 6" into the snow, that would be problematic.

I tired a off the shelf venturi, but i think it was too big, and my firepit did not flow enough gas. A smaller one maybe. But I have not taken the time to mess with it.

So 4 3/4" pipes in the corners up to waterline/top???
Spaced off the bottom as high as the burner...
