Bobbin Winder
I recently asked about a recommendation for a stand alone bobbin winder. I ordered, and received, a Simplicity Sidewinder. After examining it, the thought struck me, maybe I could make one of these. The picture is my first version. Preliminary testing is promising. It's not quite as nice looking, or compact, as the Sidewinder, but that's OK.
The bobbin spindle has a tension spring, no small post for notched bobbins, but it seems to work with 66 and 15 bobbins. And I need to plug it in to a power block to use it.
