WebStep 3. Lay the string onto a ruler with the tip located at the "0" end of the ruler. Stretch the string out across the length of the ruler and then locate the mark on the string. Read the measurement on the ruler. This tells you the circumference of the pipe. For this example, let us say the measurement is 6 inches. WebUsing the Harrington’s gauge method, pipe stem bores measured 7/64 inches which corresponded to between 1650 and 1680. Pipe stems can help archaeologists date archaeological sites. Although pipe stems can help archaeologists, large numbers of pipe stems are needed for scientific accuracy.
