Bernardo English Wheel RSM 700 x 1.5
The Bernardo English Wheel RSM 700 x 1.5 is designed for shaping concave and convex sheet metal parts, such as fenders, doors, and hoods. This updated model features a reinforced frame that allows processing of sheet metal up to 1.5 mm thick, offering greater robustness and precision. Thanks to the quick-release mechanism of the lower wheel, the workpiece can be easily removed, reducing production times. The pressure is adjustable via a handwheel, always ensuring the desired radius. Included as standard are 5 interchangeable lower rollers to create curves with different radii and one upper roller. Solid, precise, and versatile, it is suitable for body shops, restorers, and artisan workshops that require professional results.

Frequently Asked Questions
What is an English wheel and what is it used for?
The English wheel is a machine for forming sheet metal into double curvatures: two opposing rollers (upper and lower) press the sheet metal, which is moved back and forth, progressively creating curved surfaces such as fenders, hoods, body panels, and boat hulls. It is a fundamental machine for artisanal bodywork and the construction of aluminum components with complex surfaces.
What is the difference between RSM 450, RSM 560, RSM 700, RSM 830, RSM 960, RSM 1040, and RSM 1100?
The number indicates the usable working width in mm — i.e., the maximum distance between the centers of the rollers where the sheet metal can be worked. RSM 450 (450 mm) is the most compact for small pieces; RSM 1100 (1100 mm) is the largest for standard-sized body panels. The choice depends on the maximum width of the panels to be formed.
What sheet metal thicknesses can the RSM series work with?
For aluminum: up to 1.5–2.0 mm depending on the model. For mild steel: up to 1.0–1.5 mm. For thicker sheets, the required force increases significantly — check the specific model's limits in the technical table. The RSM 1100 × 1.5 indicates a width of 1100 mm with a 1.5-inch diameter lower roller.
Are spare rollers available?
Original spare parts available with 3–5 business day shipping. Italian customer support available.
Is specific training required to use the English wheel?
Yes. Forming with an English wheel requires technique and practice: the tension of the sheet metal, the direction, and the pressure of the passes determine the final shape. An inexperienced operator can create irregular undulations that are difficult to correct. It is advisable to start on scrap material to gain confidence before working on final pieces.
