Taper. The most crucial of ali block parameters is taper.
Correct taper is required to keep each successive wire wrap
climbing smoothly, só as to avoid overlapping, and wire
shooting up scenarios. The industry Standard for taper is
the measurement of the angle with a centerline or straight
edge, not the included angle. For example, a !/2° taper is
equivalent to .0175 in. on the diameter; while a 1° taper is
.035 in. The taper tolerance should be +/- .002". The basic
guideline for taper is, if the wire is not climbing, increase
the taper. If the wire shoots up, reduce taper. Also, small
diameter wire requires more taper than larger diameter
wire. Like most rales there are exceptions, and taper rales
are no different. There are two exceptions to the aforementioned
taper rales: (1) the need to create a step, and (2) the
need to create double or multiple tapers.
Double taper. A double or multiple taper
