I'm having an impossible time trying to introduce myself and my issues. So, I'll try this.
A couple years ago I bought a used Pfaff hobbylock 4762 Serger that was “complete”. I bought it from a Sun Lakes resident who had upgraded. She wasn’t part of the SNS family. I honestly bought it to do a rolled hem on delicate materials. It took many months before I was ready to dive into serging. In the process of lessons, private and group, it was discovered that I am missing part # 99371736, known as the converter (the only way to do a rolled hem!!!). I went back to the original owner with no luck. Since then I have emailed nationally and internationally, I have called or traipsed to every store carrying my machine and actually “ordered” the part from 3 separate machine locations. After months of waiting, each said it was impossible to get. During the wait we went to Ebay nationally and in Germany with no luck. My husband even contacted the CEO in Germany who quickly wrote back and informed us that the machine and its part were obsolete and impossible to find. They would not give Jim the specifications for the part even though they have gone to commercial and have divested the household part of the company. My husband has tried to fabricate the part using his engineering background. Might I say he is incredible.
