Fly

A single wing of diamond plate, ribbed with drive chain, balanced on one curved rod over a transmission drum.
Good Vibrations

Forty-five inches tall and seven deep. Three rods spring from one splined shaft, each carrying a red valve handwheel that shivers when you walk past.
Heisman

The largest of the twelve, and the only one you have to walk around. A valve cover for shoulders, a carburetor for a head, one arm out in the stiff-arm.
Skandar

Rod and spheres only — no found parts, no paint. A tapering triangular frame with weights strung down its spine.
Angry Martian

A timing chain cover read as a face: rocker arms for eyebrows, a bolt for a nose, two sprung antennae and one crooked ear.
Bearingus Arachnicus

A tapered roller bearing for an abdomen and cut flat stock for legs, sitting in a web of expanded metal held up on two lengths of rebar.
Diamond in the Rough

A red arc holds a blue sprocket in space; inside it, a cut crystal hangs in a copper cage and turns on its swivel.
CV Bloom

A constant-velocity axle planted like a stem, a camshaft sprocket for a head, two long leaves cut from plate and painted green.
Braaptor

A two-stroke expansion chamber becomes the body and tail of a bird leaning into its own noise. The name is the sound.
Malo

A six-throw crankshaft stood on end, wrapped in a single red helix. The engine’s own rotation, drawn as a line in the air.
