Thanks, frudemoo! By the way, the bobbin-winder thing, I "solved" by replacing the rubber "doughnut" in the bobbin winder with a rubber doughnut of slightly smaller thickness. This way, it still engages with the large wheel for bobbin-winding, but it does not contact whilst sewing. I still think perhaps the mechanism is spring-loaded backwards from how it should be, but oh well! ;-) For now, it works. How do you deal with yours? Does yours stay in contact with the large handwheel whilst sewing?
But, if your manual has detailed drawings which help, then yes, do share! I have a German-language user manual which I am happy to share if you need anything - but the problem is, these things are not addressed in my manual. I was fortunate to have a German-fluent houseguest last week. We had a good giggle over Spulenkapsul and ZickZack! I have, owing to this, re-named The Beast; his new name is Ziggy! ;-)
