In their defense the squeak wasn't there when it left the shop as I sewed on it for an hour at home with no problem. So, had I tried it in the shop I would have been happy. It's just that it reappeared within 2 hours of use. It will sew for 3 or 4 minutes fine then a few squeaks, then sew another minute or two, then squeak, squeak. And it sometimes squeaks when I use the knee lift. The idea of taking a video is a good one if I can get it to squeak that would help.
