The shrinker/stretcher is used to fabricate gentle radius bends and contours in steel, aluminum, stainless, or copper. It is ideal for almost any metal fabrication requiring a combination curve and angle. For example, forming complicated patch pieces for automobile areas like rear wheel arches, dog legs, window edges, and trunk edges. Use the shrinker to contract metal for inside curves; use the stretcher to expand metal for outside curves.
The Eastwood 28053 shrinker/stretcher is a hand-operated press that multiplies your pressure by a factor of 45, creating leverage to work on up to 18-gauge mild steel, 20-gauge stainless, and 16-gauge aluminum without making relief cuts, heating, or hammer-forming.
