Can anyone tell me why people file off the end of the minute wheel cock so the hour wheel is free to fall off the movement? This is the second one in a row where someone has done just that. The hour wheel is free to float and is only held in place by the minute hand. The probability that the same person worked on both of these is extremely low, so the practice is somewhat widespread. My wife has an affinity for these clocks and I end up working on them.Most of them are quite well made and the problems I encounter are usually attributable to poor workmanship by some less than skilled repair person somewhere along the line.
