Is there an easy way to recreate the ACLU modern engraving effect in Photoshop?

In the ACLU Design Handbook (9.5MB PDF) the use of the so called "modern engraving" effect is detailed on pages 135-137. What would be a good way to achieve this look in Photoshop (or Illustrator, fwiw)?

Ideally, I'd be looking for a way that

• does not require the installation of plugins or actions and can be created with the default tools available in Photoshop


• produces somewhat smooth lines, see example image #2


• allows for the direction of the lines to be adjusted easily (eg, not using a fixed pattern)


• is possible to do in a reasonable time, without too much work (or layers)

Example 1

Example 2

The duotone color effect can be added with a simple gradient map layer style, so it's not strictly part of the question.
