Steve, jlm549's quilt is like the one I'm doing. It's for my daughter's 25th wedding anniversary and I'm about 1/2 done. It's going to be a queen size.
Cricket, I took everything apart and didn't find any stray threads.... and cleaned out the bobbin area really well. When I turned the hand wheel, the feed dogs move just fine. When I put a piece of cloth in, the feed dogs move one stitch and stop moving. So, there isn't really anything holding it back.... it's something else. Also, when I press down on the foot pedal, the needle goes up and down 3-4 times and then it just stops.
I took it in today. Hopefully it won't take them too long to figure out what is wrong. I'm very comfortable working on my old singers..... but this one has some computer parts..... ARGG!!! I don't do computer machine repairs. I have to rely on the authorized Viking repair to work on this machine.
and, I do have vintage machines that I could use.... they are 10 hours away..... where I spend the winter. I have other quilting things I can do.... just really was wanting to get those quilts done so I can put them on the beds in the guest room.... I'm having guests at the end of the month. They will get done. Next summer I may bring up a few of the vintage machines and leave the fancy Viking down south!!
