Steampunk Mechanical Arm Prototype on a Workbench

How to use this prompt
"Polished brass and copper" rather than just "metal" — the two-tone material story (warm brass, cooler copper) makes the arm read as hand-built. "Visible gears and pistons" must be stated explicitly — without this the model produces a smooth metal arm that looks robotic. "Leather straps and a padded elbow joint" is the Victorian prosthetic detail that separates this from a sci-fi cyborg arm. "Glass pressure gauge on the forearm" is the detail that sells the steampunk premise — a gauge means the arm runs on steam, not electronics. "Cluttered" workbench matters because a clean bench reads as a display case.
Variations to try
- Replace the arm with a mechanical bird automaton mid-assembly with wings spread
- Swap the workbench for a wooden ship's deck with rope coils and brass portholes
