There's a lot of discussion of "track geometry" vs "road geometry" here, but I'm curious how many people are actually cognizant of geometry that works well for them in one way or another. I mean, there's a lot of overlap between what some of the track builders do for track frames (Italianate influenced closer to 74/74) and what some of the modern material road builders are doing (very sharp head angles, like 74.5/73.5 or so.)
There is no "right way" to choose your geometry for a track frame -- some builders choose differently than others. I'd be interested to hear Don or Richard or Sacha weigh in a bit about their choices in geometry, or the thought processes involved rather than continue uninformed blathering
