3. Measure the length of each of the 4 "branches" at the 4 red points indicated in
Record the value from each location in a worksheet similar to the one shown in
4. The central spine has three different dimensions that need to be measured. At either end is
the 0.50 inch and the 0.25 inch measurement. Measure in two places at both the top and
bottom for a total of four measurements each as shown in
measurement runs through the center spine between the previously measured dimensions.
Measure at the points indicated in
5. Average the values and subtract the average from the expected value to determine the
amount of error. Use the error and nominal values to determine the slope to generate the
shrink adjustment value. Use the 15 inch tree shrinkage spreadsheet to automate the
process or use the formula, =SUM(-SLOPE(X1:X7,Y1:Y7)). The result can be subtracted
from, or added to 1.000. for example a slope of -0.0024 for Y would result in shrink of
0.9976.
