Cubic Precision (K&E) Alignment Scales

These scales are made of hardened tool steel (invar--low coefficient of thermal expansion (0.9 x 10^-6/ °C)) with a white matte surface. The paired-line graduations are black to provide maximum contrast.

On the English graduated scales the center of the space between each pair of lines represents .100 in. and is accurately located to within +/- .001 in. (at 68° F) from the zero end of the scale. Four pairs of lines, each with a different separation, are provided at each .100 in. for different lengths of sights, as follows:

Separation in Inches	Sight Distances in Feet
0.004	Up to 7
0.010	7 to 20
0.025	20 to 50
0.060	50 to 130

The 3, 10, and 20 in. scales are graduated throughout their length. The 40 in. scale has the first 19 1/2 in. blank and the last 20 1/2 in. graduated. Graduations are numbered at each .200 inch. Inch numbers are repeated between every sub-number for easier reading.

On the Metric graduated scales the center of the space between each pair of lines represents 2.0mm. and is accurately located to within +/- 0.02mm (at 68° F) from the zero end of the scale. Four pairs of lines, each with a different separation, are provided at each centimeter for different lengths of sights, as follows:

Separation in Millimeters	Sight Distances in Feet
0.1mm	Up to 7
0.2mm	7 to 20
0.6mm	20 to 50
1.2mm	50 to 130

Graduations are numbered at each centimeter and sub-numbered at each half centimeter.

KE-71-6065	Scale Holding Magnet for 3, 10, 20 inch and 25 cm alignment scales			$239.00
KE-71-3270	Alignment Scale level			$325.00

The magnet holds 3, 10 20 in. and 25 cm optical alignment scales at right angles to the finished surface of any magnetic metal. Overall size 2 in. x 2 in. x 1 in.

This level sets optical alignment scales vertically or horizontally. It can be attached to any steel scale, up to 1/8 in. in thickness, and between 1 in. and 1 1/2 in width. Both of the vials have a sensitivity of 15 minutes of arc per 2mm movement.
