Here is detail of the an inner tube of the Meyers Demonstation Unit. The tube IT4 shows evidence of being drilled(as do IT3 and IT1) The mark on the opposite side on the inner wall of IT4 shows the drilling did not go all the way through

This is interpreted as follows: The ratio of the caliper measurements is very close to the ratio of the
reported diameter of the inner and outer tubes
The value of the caliper value of the hole is consistent with a 0.125 diameter hole when related to known values of the inner and outer pipes
The confidence level is 99% (at least 5 matrix cross links of high reliabilty)
This is based on known dimensional string consistency
This is based on english drill size matrix
This is based on availabilty of .125 diameter plastic rods
The is based on D9 statement on diameter of the upper tube spacers

This is interpreted as:
Stan may have drilled some test holes before he started to make holes for the spacers because of drilling difficulty or bit breakage.
Stan may have reduced mass of the tubes in an experiment or method of adjusting acoustic frequency
