What It Made Beyond Gunstocks

The gunstock was the application that got the machine invented and paid the nine-cent royalty, but it was never the biggest business. A machine that copies any irregular wooden form is a machine that copies a lot of things people used to whittle by hand, and Blanchard — a relentless licenser — spread the principle across the whole nineteenth-century economy of shaped wood. This volume covers the sprawl: what else the lathe made, and the licensing empire that put “over fifty” of these machines to work.

5.1 The Product List

Confirmed across multiple sources, Blanchard-type lathes turned out:

Shoe lasts — the foot-shaped wooden forms cobblers build shoes around. One account claims six to ten pairs per hour on a single machine, and the technology is credited with helping standardize shoe sizing — a genuinely large downstream effect, since consistent lasts are a precondition for consistent sizes.¹²
Axe handles and tool/hatchet handles — the classic curved, non-round handle, exactly the kind of shape that resists ordinary turning.
Wheel spokes — tapered, shaped, and produced in enormous quantity for the wagon and carriage trade.
Hat blocks and hat forms — the head-shaped forms milliners blocked hats over.
Tackle blocks — the shaped wooden shells of ship’s pulley blocks.
Piano legs and wig stands — decorative shaped work.
Plaster and wood busts — the application Blanchard famously demonstrated before Congress in the Capitol Rotunda around 1840, carving portrait busts to argue for his patent extension (Volume 2).¹

One item on the brief’s list deserves a flag: oars. Oars are a natural fit for the “irregular wooden form” category and are highly plausible, but the research found no source that independently confirms Blanchard-type lathes made oars. This series lists oars as plausible-but-unverified rather than as fact.

5.2 The Shape of the Product List

Step back and the list has a logic a machinist will recognize instantly. Every item is a shaped, non-round, repeated-in-quantity wooden part — the exact overlap of “can’t be made on a plain lathe” and “needed by the thousand.” Shoe lasts and hat blocks are body-form copies; handles and spokes are tapered asymmetric sticks; tackle blocks and busts are free-form solids. Anything symmetric (a rung, a dowel, a baseball bat) stayed on the ordinary lathe because it did not need Blanchard’s machine. The copying lathe carved out precisely the niche of high-volume irregular wooden forms, and it dominated that niche for decades.

There is a second-order effect worth naming, because it shows how deep the machine reached into daily life. Standardized shoe lasts did not just make shoes faster to build; they made shoe sizes mean something. Before consistent lasts, “a size 9” was whatever a given cobbler’s block happened to be; a machine that reproduced an identical last, thousands of times, is a precondition for the ready-made, sized footwear industry that followed. The same logic runs through the rest of the list — a wheelwright buying identical spokes, a hatter blocking on identical forms, a rigger fitting identical tackle-block shells. The copying lathe did not just speed up shaped-wood work; it made shaped-wood parts interchangeable within their own trades, which is a quieter version of the very interchangeability story Volume 6 examines for firearms.

5.3 The Licensing Empire

Blanchard did not run one factory; he ran a patent. His business model was licensing the principle, and the reach was wide: during the patent’s first term, one account records “no less than fifty machines… in operation for various purposes, turning shoe lasts, wheel spokes, tackle blocks and hat forms.”¹ By the 1840s extension fight, the piracy problem had grown to “over fifty unauthorized machines… across the country, including Canada” — a number that tells you both how valuable the principle was and how hard it was to defend.¹

This licensing sprawl is why the machine matters far beyond firearms, and it is also why Blanchard held roughly two dozen patents (sources vary between about 24 and 25-plus) across his life.³⁴ The gunstock lathe was the crown, but he was a career inventor with a portfolio, managing it aggressively — the subject of Carolyn Cooper’s Shaping Invention, flagged elsewhere in this series as the definitive (and, for this research pass, un-fetchable) source on exactly that management.

5.4 The Later Blockbuster: Wood Bending

Worth noting because it is often mentioned alongside the copying lathe but is a distinct invention: Blanchard’s wood-bending machine, patented around 1849-1851, for bending ship timbers and other heavy stock. One source calls it his most commercially lucrative invention, reportedly earning $150,000 from shipbuilding applications alone.³ This is not the copying lathe and should not be conflated with it — but it rounds out the picture of Blanchard as a man whose single best-known machine (the one this series is about) was, financially, not even his biggest hit.

5.5 Why This Volume Belongs in a Firearms Dive

Because it reframes the copying lathe correctly. To a gunsmith it looks like a gunstock machine; historically it was a general-purpose irregular-form copier that happened to get its start on gunstocks at a government armory. The gun connection gave it prestige, a captive high-volume customer, and a royalty; the rest of the economy gave it scale. When Volume 6 argues about the American System of Manufactures, keep this breadth in mind — the same machine that standardized musket stocks was, at the same time, standardizing the shoes on people’s feet.
