Engineer side, up

This is an example of how we mark parts. Although many parts look identical, subtle differences preclude their interchangeable use.

The machinists drill holes, for instance, to match the companion part. Often, the parts will not fit when reversed.

Keith and Alberto manufactured a pair a brackets two weeks ago. The brackets will be riveted to the water tank and will hold the ladder in place. The ladder hangs off of the rear of the oil tank.

Last week, Keith stamped each piece so we know which side it fits on the ladder. The pictured bracket, left, fits the engineer's side of the Diamond and Caldor No. 4. The backing plate was marked as well. Companion pieces were measured and drilled for the fireman's side mount.
