I wound my bobbins on a stand alone bobbin winder.
I use Arcopac Oil 90, which I use on my industrial machines.
Just finished oiling it, rethreading, put in new thread in the bobbins.

It came in that wonderful cabinet with a stool. I emailed Jenny at sew-classic.com for the parts I need.
I actually love Lucy for a name, I don't know what I'm calling her.
