I'm not in a position to do any more measurements today. Perhaps another can help out with additional measurements?

Is your math right? Gears are same thickness and have the same number/size of holes.

120T area = pi * ([120/32] / 2) ^ 2 = 11.045 sq. in.
80T area = pi * ([80/32] / 2) ^ 2 = 4.91 sq. in.

Density Ratio = 0.444

80T Weight estimate = 0.444 * 114.71 = 50.93 g
