Forming the Columns - Rebar and Boxes

For all footings over 3 ft tall we place the stirrups 6" apart for the lowest 25% of the column height, then 8" apart for the middle 50% then 6" apart for the upper 25%. We use #5 rebar. The lumber is untreated, termite food, so when we're finished with it we'll take the 2x4 pieces not covered in concrete to our Maho Art Center to use in the Clay Studio wood burning kiln.
