A cylinder of 1/8" diameter (radius (0.15875 cm.) 9 mm. long in a wood of relative density 0.8 (such as a heavy maple) will have a mass of 0.057 grams, which you would need a pretty accurate scientific balance to measure. pi * ((0.15875) ^ 2) * 0.9 * 0.8 = 0.057 This would make a difference of just over a quarter of a gram at the touch. To put it another way, 1.5 grams is the mass of a cube of water of side 11.4 mm, and the density of wood is considerably less than that of water. Any detectable difference achieved by drilling a hole in the moulding will be due to the human imagination rather than to any natural law. JD
