  • 4. First Cuts - For large logs (more than 18 inches in diameter), initial mill cuts usually are made by a "headrig," consisting of a headsaw (may be a band or circular blade), a carriage loader for handling, and a turner to rotate partially sawn logs. "Full-taper" saws cut around a large log to a tapered core to get the outer lumber. "Half-taper" saws cut smaller logs in which quality is similar throughout, orienting the log's pitch so it's parallel to the saw line.

    Western Red Cedar

    The "tree of life" in the Pacific Northwest, rot-resistant cedar is harvested for siding, shingles, decks, and more. We follow its progress from forest to factory.

     
  • ProspectingFor stone to be extracted from the ground and fabricated for architectural use, the first step is finding deposits that will yield large, roughly cubic blocks that can be cut into smaller blocks, or, more commonly, slabs that are thin and flat. Cylindrical borers drill down as far as 5 meters for sectional samples of stone to determine precisely its properties and its potential to yield commercially viable blocks.

  • A Quality Brick Product Depends on Brick Ingredients

    Whatever the desired shape or manufacturing method, making brick depends on brick ingredients: the alchemy of shale, clay, water, and fire.

     
  • Concrete Masonry Units

    They look dull and, in fact, if you've seen one concrete masonry unit—or concrete block or CMU—you may think you've seen the lot of them: Usually they're rough, gray oblong blocks formed from water, sand, crushed stone, and cement, with two big holes in them.
