Long before I became a builder, I used gasoline-powered portable cut-off saws in the Air Force for crash and rescue recovery work to cut through automobile and airplane wreckage and buildings. I left the Air Force long ago, but not the saws. Now I build homes in Santa Fe, N.M., and work with as much adobe, concrete, stucco, and re-bar as I-joists and OSB.
