2 big inlet dampers vs. 4 small ones

[keny]

Is there any advantages to having (for example) 4 small firebox inlet dampers over having 2 big ones of equal square inches? Like four 3" x 6" instead of just two 6" x 6"?

No...but according to Feldon's calculator I need 55 square inches. The question was sort of general...all my measurements can be found here in a thread titled "is Feldon's calculator really flawed?"

I see. Two up high and two down low would be best. Makes sense.

Make it around 25% up top and the rest at the grate level.

I want to add an ash pan to the FB also. Does it need to be made out of 1/4" steel like the rest of the FB, or can it be lighter? 1/4" pan would be pretty heavy...

Thin is fine for the ash pan, make it easy on yourself.
