Where can one find drawings of the "cam type" of wiring boards? Using pliers
very carefully I get my wires tight enough but the idea of the cam intrigues
me, particularly for brood frames where the end bars are longer and can be
compressed easily.
   I like to wire the frames because the wire serves to locate the
foundation more accurately in the center of the frame, resulting in more
uniform comb.
  I like working with the wax and the wood, enjoy the smell of them, and
using the electric "embedder".  Plastic may be easier, but it just wouldn't
be the same.
