I try to avoid technical matters here in the blog on the grounds that we have an entire magazine to cover the "hard stuff." Besides, very few topics can be adequately handled in just a few hundred words. My last posting mentioned herringbone gears though and it occurred to me that many of our younger readers may be completely unfamiliar with this once dominant gearing system. So if you think fabric patterns or deck planking when you hear the word "herringbone" — this week's blogs are for you.
