 To set an angle on any sine device, whether it is a sine bar, sine plate, compound sine
plate, or other sine tool, you must first determine the center distance of the device (C)
and the angle you wish to set (A).
 Next, you must look up the 'setting constant' in the appropriate table.
The sine
tables provided in this booklet are the basic sizes needed to set an angle on most sine
products. For center distances other than those sizes listed, use the appropriate multiple
of the constant determined from the basic chart.
For example: to obtain the constant needed to set a 15 degree 12 minute angle on a
10" sine plate, look up the constant in the 5" chart and find 1.310946".
Multiply this by 2 and the result is 2.621892"
 After determining the appropriate constant, assemble a stack of gage blocks (G) equal in
size to that constant.
 Place these gage blocks under the gage block roll of the sine device, and the desired
angle is set.
 Tighten the locking mechanism on those devices that have one, and you're ready to go.
