I have a question for the gear gurus. The first gear has 54 teeth, 7.980 OD and measures 7.935 over .247 pins, yes, the teeth are higher than the pin. Measure 8.074 over .288 pins. The DP appears to be 7 and 20PA as checked with my pitch gages. Measuring span it comes out to 1.545 over 4 teeth, 1.963 over 5 and 2.382 over 6.

The second gear is 30 teeth,5.795 OD, measures 5.665 over .288 pins and 5.864 over .345 pins. Spans are 1.383 over 3 teeth, 1.900 over 4 teeth, and 2.422 over 5 teeth. None of this comes out close to anything even as far as numbers. Big question is what in the world am I working with? Help a guy that is still learning.

An included pic may tell you more as it shows the first gear profile and a .288 pin.

Thanks, Ed.
