I am curious how long a cam used w/ a bronze gear might still be OK to convert to one of these treated gears, considering the wear "should" be on the bronze gear up to that point.

Hard to tell because of the angles of the pics... trying to see if the two gears' wear patterns are noticeably different. scope
