Antique Screw-Arm Plough Plane | Hardwood & Brass | 19th Century

A tool this precisely made was never just an instrument — it was an argument about the standard to which work should be done.

The plough plane is among the most mechanically sophisticated of all traditional hand tools. Where a bench plane smooths a surface, the plough plane cuts into it — running a guided iron along the grain to produce the grooves, rebates, and housings that hold joinery together. Without it, the dovetailed drawers, panelled doors, and tongue-and-grooved boards of nineteenth-century furniture and architecture would have been considerably harder to execute with consistency.

The screw-arm configuration represents the more refined end of the form. Instead of a simple wedge-fixed fence, this system uses threaded wooden arms to allow precise, repeatable adjustment — a feature particularly valued in cabinetmaking where accuracy and repetition were essential. Examples of this type were produced in quantity across England and America during the nineteenth century, though survival in complete and functional condition is increasingly uncommon.

This example follows the English pattern and is constructed in a dense, dark-toned hardwood with a rich reddish-brown patina built up through long handling. The body is substantial, with a stepped and moulded sole profile. The fence is mounted on two turned wooden screw arms, secured by four original wooden locking nuts with brass-capped tips — all present and intact. A brass depth stop is fitted to the body and secured with slotted screws. The iron is present and seated behind the wedge, which is topped with a turned finial. A shaped wooden tote rises from the rear, and the steel skate remains in place.

No maker’s mark has been identified on the body.

The plane is in good condition for its age. The wood retains its original surface throughout with no structural cracks, splits, or losses. Minor age checks are visible to the tote but remain surface-level only. The brass fittings show expected oxidation consistent with a working tool. The screw arms retain clean thread definition and the fence adjusts as intended. The blade iron is present; the cutting edge has not been tested.

Collector Appeal

Complete, well-preserved screw-arm plough planes of this type occupy a distinct position within the hand tool market. The presence of the iron, intact screw arms with brass-capped nuts, and a fully functional fence places this example above the many incomplete or compromised survivors. The absence of a maker’s mark allows the quality of construction and material to stand on its own — often preferred by collectors who value form and function over attribution. It will appeal equally to collectors of traditional woodworking tools and to those drawn to objects that remain both legible and usable within their original context.

Every groove this plane cut was a measurement kept — of a craftsman’s eye, and of the standard he refused to fall below.
