Fastest in-shop machine repair ever. Today I was stitching along and noticed that a small screw was bouncing along on my hoop. Stopped the machine and opened it up and looked everywhere. Couldn't see where it came from. Called the shop and described the specialized little screw and mechanic told me 4 places to check. That wasn't it, so, down the stairs, into the car, and into town. It took him about 6 minutes of comparing the inside of my machine to the inside of the floor model and - voila! Back in business. He said it had probably just worked its way loose from vibration (had it around 3 years). Only got one item stitched out today, but tomorrow, I'll be back at it.
