Frequently Asked Questions
What is an English wheel and what is it used for?
The English wheel is a machine for forming sheet metal with double curvature: 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 the fundamental machine for artisanal coachbuilding 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 useful working width in mm — i.e., the maximum distance between the centers of the rollers where the sheet metal can be worked. The RSM 450 (450 mm) is the most compact for small parts; the 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 does the RSM series work with?
In aluminum: up to 1.5–2.0 mm depending on the model. In 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 lower anvil.
Are replacement rollers available?
Original spare parts available with 3–5 business days shipping. Customer support available in Italian.
Is specific training required to use an 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 definitive pieces.
