To determine the Glass Rate Meter calibration number for any glass yield
not given in charts C and D calculate the calibration number as the
example below.
VRC-2000-XXX, Pro Chopper and 4 Strand Chopper assemblies (70020-X)
Example: Yield 205 yds/lbs
Rotor circumference:

VRC-2000-XXX, Pro Chopper and 4 Strand choppers (70020-X) = 3.7699 in.

6 Strand Chopper Assembly (70010-1) = 5.4035 in.
1. Multiply yield number by 36 (inches in a yard).
205 yds 36 in
1 lbs 1 yd
2. Divide the circumference of the chopper rotor in inches by the glass
yield in inches.
3.7699 in 7380 in
1 rev 1 lb
3. Multiply the result of step 2 by 60 (the seconds in one minute).
.0005108 lbs 60 sec
1 rev 1 min
4. Multiply the result of step 3 by the number of strands.
.03065 x 2 strands = .06130 calibration number for 2 strands
x = 7380 in / lb
x
= .00005108 lbs / rev
x = .03065 calibration number for 1 strand
