Ernest pulled a heavy T-square down across the grid paper, aligning it to the center axis. He picked up a 2H pencil, pressing light guide lines into the vellum.

"In an ideal world, I'd drop in a corrugated Fox firebox," he muttered, tracing the outer boundary of the combustion chamber. "High heat transfer, great structural rigidity against collapsing pressure... and zero chance Teucher Shop No. 2 can bend corrugated plate without cracking it down the seam."

He tapped the side of his thumb against the desk. Reality check time.
