Jim and Vikki --
Thanks so much for the good information. Of course the responses generated more questions on my part.
I just took a good look under the bobbin case. The case itself doesn't look damaged, but I thought I'd get one anyway. The white plastic piece under it was scratched in the first few weeks I had the machine (it's now 5+ years old) and "the guy" said he could just buff it out and it would be as good as new. I think that started me down my path of love/hate relationship with the machine. I don't think buffing it out was the thing to do and if any other damage was caused at the time, it was not checked. There is no doubt that it should be replaced now. What I can't figure out is what could I have done to scratch it?
If they don't have the parts, can you describe what "good long while" might mean? Weeks? Months? I will tell him about ordering those things when I hand the machine over. If they don't have those things in stock, perhaps they would order immediately and save a little time. In the meantime, I'm also taking in my ancient Kenmore for service. I may need to resort to using it. I do not need another new machine as I have machines of various kinds that line two walls.
They do want me to bring in my embroidery unit, foot pedal, and power cord. I have those things packed and I put labels with my name on EVERYTHING, as I always do. I've taken it in maybe four times over the 5+ years I've had it (for various reasons) and they haven't lost anything--yet.
At least for now, we are keeping the boxes in the basement. With all the other stuff to be thrown away or donated, what difference could a couple of boxes make?
