  3. Find a straight rod between 8 in. and 12 in. (203 mm and 305 mm) long. Verify that it's straight: roll it on a known flat surface (like a granite surface plate).

    You'll use the rod to verify that the ATC is correctly installed on the mill, so it must be straight.

  4. Put the alignment rod into a tool holder.

  5. Put the tool holder into the fork so that the groove in the tool holder slides into the fork, and so that the drive slot aligns with the dog. Don't rest the tool holder on top of the fork.

  6. Put a machinist's square on the machine table.

Examine Perpendicularity in the Y Direction

  1. Verify that the rod is perpendicular to the machine table in the Y direction: compare the rod's position to the vertical edge of the machinist's square.
  2. Loosen the flange nuts on the standoffs.

  3. Turn the tilt standoff with an adjustable wrench, and slowly pivot the ATC until the rod is perpendicular to the vertical edge of the machinist's square.
