Stretch and shrink machines

A stretcher and a shrinker let you stretch or shrink sheet metal so it can be formed into a curve. According to the description, the stretcher is used for inside curves and the shrinker for outside curves, for example on wings, wheel arches or curved flanges.

This category contains Cowley products: a stretcher and shrinker set, a version including stand, a separate stand and a portable stretching and shrinking tool for working on site or on large panels.

These machines are used by coachbuilders, restorers, sheet metal workers and hobbyists. Combine them with an English wheel or planishing hammer from Metalworking.
