Flipping the spool in the bobbin won't work, you need to flip the
outer spool on the auto-hub if the thread is wound the wrong way.
However, I suspect that what he meant was not that the spool rotated
the wrong way, but rather that the hub doesn't have enough tension to
stay put. This is a feature (I would say a major flaw) of the new
Norbobbins (the ones with quick release hubs). The old ones (with a
bolt locking the hub in the frame) have adequate tension. Norm sez
that he deliberately designed the new ones with less tension, because
he had so many hubs returned with broken springs. A workaround, which
Norm suggest himself also, with the new bobbins is to wrap the thread
once or twice around one of the legs of the frame. Still doesn't make
the thing work like the old ones, but it will usually stay put.
I've since moved on to an Ekich automatic bobbin -- takes standard
spools and works beautifully.
