I just bought one a week or so ago - and everything seemed fine - until I tried to drop the feed dogs.

Uh-oh. That knob is not moving.

Okay - it is turning - very very very reluctantly.

Long story short - after getting it to move - and moving it back and forth many times, it is moving freely.

Whew!

After opening the cover and watching what happens when the feed dogs are dropped - what happens is a lot more complicated than I thought.
