Hi,
I wind the bobbins for my singer 29 with a cordless drill.
Just get a bolt that fits the center hole of the bobbin pretty snug, lock the bobbing onto the bolt with a nut (hand tight) and insert the bolt into your drill.
You will have to use a thread tension disc set-up of an old bobbin winder - this is a real fast way to wind bobbins - especially if you have a hand wheel that has no provisions to free wheel and you don´t want your machine to go clickety clack while spooling up thread.
Hope that helps you out.
Greetings from Germany
Hans
