jhz563 posted:I picked up a cute little Hornby at York last fall. I really like it but it just doesn't go as far as it did for the first few wind ups. I checked it for debris, oiled all over. Not sure what the issue is. Although the first few wind it seemed to take more tension. Now after a few turns there is a pop noise - like a wind stop maybe? Don't know if its actually working as designed or not, it the only one I have!
If it is popping, it sounds like the spring is broke unfortunately. That is usually a sign of the tension releasing. Sometimes it could be broke where it attaches to the winding axel and can be fixed. I haven't worked on clockworks, but did work on a pull-start spring. I don't have great advice on how to work on them. I just know it isn't easy. One thing to do is to lock the spring with something like a zip tie before disassembling the drive.
