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. Alternating between the two functions allows complex shapes to be achieved on thin sheet metal without wrinkles or tears. An essential tool for bodyworkers, boat builders, and vehicle restorers.
What sheet metal thicknesses can the Bernardo Shrinker and Stretcher SS18 process?
Bernardo shrinkers/stretchers typically work 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 SS18. Exceeding the limits causes damage to the tools and irregular deformation of the workpiece.
What is the difference between the lever, foot-operated, and motorized versions?
The lever (Pro) version is manual: the operator activates 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 work. The motorized or electric version automates the entire cycle for series production.
Do the jaws wear out? Are spare parts available?
Yes. The jaws of shrinkers/stretchers wear out after prolonged intensive use. Original Bernardo spare jaws are available with 3–5 business day 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 compared to mild steel. For specific alloys, check thickness limits with Krollit. Italian customer support available.
