The Richmod gears that Cass sent me last month had a spec for pinion depth to be measured at the head-face of the gear. I started with .090 under the pinion and just checked this with a simple caliper. Measurement was within a few thousandths of spec, so I moved on to looking at the pattern and fine-tuning that with the side adjusters.
