Frequently Asked Questions
What does a shrinker do and what does a stretcher do?
The shrinker compresses the metal fiber at the edge, shortening it and creating a concave curve. The stretcher elongates the fiber by expanding it, creating a convex curve. By alternating between the two functions, complex shapes can be created on thin sheet metal without wrinkles or tears. An essential tool for bodybuilders, boat builders, and vehicle restorers.
What sheet metal thicknesses does the Bernardo Shrinker and Stretcher SS 70 work with?
Bernardo shrinkers/stretchers typically work with steel up to 1.2–2.0 mm and aluminum up to 1.5–2.5 mm depending on the model. Check the specific limits in the technical table for the Bernardo Shrinker and Stretcher SS 70. Exceeding the limits will cause tool damage and irregular deformations on the workpiece.
What is the difference between lever, foot-operated, and motorized versions?
The lever (Pro) version is manual: the operator operates the lever with both hands, ideal for occasional work. The foot-operated (FD/F) version operates the machine with the foot, freeing both hands to hold and guide the workpiece—more convenient for repetitive tasks. The motorized or electric version automates the entire cycle for series production.
Do the jaws wear out? Are spare parts available?
Yes. Shrinker/stretcher jaws wear out after prolonged intensive use. Original Bernardo spare jaws are available with 3–5 business days shipping. Replacement does not require special tools.
Does it also work on copper and brass?
Yes. Copper and brass are more ductile materials than steel: the actual capacity is higher than for mild steel. For specific alloys, check thickness limits with Krollit. Customer support in Italian available.
