BBQ Pit

Anyone make a BBQ pit out of bricks/blocks, mortar, and steel grating?
There are a lot of designs out there, and I want to make a decent one on the
first try. I will probably make it out of block, concrete, some steel
piping, flue liners, metal roof. Just wondering if anyone had built one,
had any suggestions, or warnings, that's what I was asking.

Experiences, hints, caveats, do-overs, facts, etc. appreciated.
