Drum Roll, Please

 Or, How Buddy Folly has changed.

I put this all back together.  I was pleased with how smooth the hook felt when I turned the handwheel.  With the feed dogs in place, though, it was binding up.  I figured out that somehow the feed dog height had been changed. I fixed that but discovered, in doing so, that the feed dog lifter roller does not roll. 

I think I may have to just keep Buddy.  I sure hope it stitches well.
