Reply to "Jones Counter Redesign"

I finished a 500 mile test at 20 mph, and it went pretty much as I hoped. Minor wear on the plastic gear teeth, the metal ring gear, and the retainer cup were observed.
The retainer cup was seen to wear approximately 0.10 mm as the ring gear cut a groove into it, finishing at 24.55+/- 0.02mm.
Interesting enough to note, the ring gear grew by 0.03mm, finishing with an inside diameter of 24.72mm +/- 0.01 mm. The inner rim formed a sharp edge along the inside that can just be felt with the fingers. The root diameter remained a constant 24.75mm, measured opposite the sharp edge. Minor abrasion on the sides was barely able to remove the surface rust, and depth of wear is on the order of 0.02mm at the most.
The plastic gear held up very well, and a small, polished indent formed on the face of the teeth approximately 3mm wide, and 0.25mm deep. The width of wear is due to the slight wobble as the ring gear (made from 0.75mm, or 0.032" steel) rotates. The "leaflets" that grew were easily brushed off, and had the consistency of grease when rolled in the fingers.
No observable difference in the counter itself was noted before and after the test. Veeder-Root makes a fine counter.
The unit operated with little noise (aside from the drive motor) and no heat buildup during the test.
I've put the finishing touches on the 3D model, and have started the working documents for production.

Best,
Tom
