      Yes, 4 risers, not connected together except by the casting itself.
      The gate was about 1" wide and 1/4" deep going into each of the
      risers on the R. end, coming from a tapered sprue about 3/4" dia. at
      the base and 7/8" at the top. My headstock pattern was about 1"
      larger in height from parting line to top and 1/16"-3/32" thicker
      than the one in the book, otherwise I followed Gingery's dimensions.
      Also, I deepened the raised area between the clamp pads in an effort
      to prevent too abrupt a change in cross section area.
