When metal passes between the upper and lower
dies, a “track” or shiny line is pressed into the metal.
Various tracking patterns can be used to shape work-
pieces depending upon their shape or size.
Bellow are a list of patterns and their use.
Zigzag Pattern
This pattern can be used for a series of forms.(Fig. 4.1)
Note: Try keeping the tracks close to each other
in a consistent pattern
Star Pattern
The star pattern is useful for shaping round
workpieces. (Fig. 4.2)
Note: Avoid rolling directly over center of
workpiece, as too many passes could overstretch the
metal.
