I have a dual feed foot for my Viking. It's always worked just fine. Once in a while the movable part of the foot comes off but I've reattached it successfully in the past. This time I hit a rough patch and it was more than just reattaching that part. I opened up the side of the thing and POP! out come it's innards! I tried and tried and couldn't get them back where they belong. What really makes me feel stupid is that there are only 3 (count 'em) 3 parts!!!
I've emailed Viking but my better bet is the Yahoo group for my machine. A nice, very active member who's technically savvy, replied to my post for help and will be sending me pictures of his dual foot (insides I'm assumming) so I can get mine back together.
Isn't that nice??? I LOVE online communities! (This one is really special though, ladies. That was my first post to the other one, I swear!)
