That's an excellent review Vic. I see that the extra 25 thou I figured would only go in if there was at least that much 'slogger'. I tried a half-cut tooth, some time ago but found no real benefit. The best result was the leading tooth on the quadrant cut back at an angle on its' trailing face.(but retaining full height). That seems the least chance of end to end jamming as the two points are the thinnest on contact. I did spot that thinning/sharpening the teeth on the small gear would be a benefit but assumed the reduction in contact might result in damage to the gear.
Interesting problem, thanks for the comments and suggestions.
