Default Re: Metamec A909 clock- broken coil

I've successfully rewound simple coils using a hand drill held in the bench vice with the coil former mounted on a piece of rod held in the chuck. I've also heard of something similar being done with an electric screwdriver.

The trouble with any form of powered coil winder, when winding thin wire, is that the wire tends to snap due to the sudden jerk when the motor is started.

If the wire is wound off a rotating spool this can also put strain on the wire. For this reason spools of wire generally have curved end cheeks so that the wire can be pulled off the end of the spool without having to rotate it.
