Measurement of Carbon Fiber Rods in the Garage

Request \# 76 02-OCT-2008

Project \# 76 C. Wilson

Completed the measurement of 2 Carbon Fiber Rods (CFR's) used for
precise level runs in the Tevatron. The scale holders on both CFR's were
replaced with new scale holders

and secured using Loctite "Blue".

New values for the CFR's

CFR #1 1.064720 Meters or 41.918104 Inches

CFR #2 0.980757 Meters or 38.612497 Inches
