Abstract
A method and tools for forming ridges or dimples in tubular members such as copper pipes is provided. A manual tool has a pair of jaws which can be adjustably positioned and has a threaded ram affixed to one of the jaws for rotation. The jaws are adjustable for holding various thicknesses of pipe walls in firm engagement as the ram is manually rotated to form a ridge in the pipe wall. A hydraulic tool is also described for high production requirements.
