I have seen springs coiled using an electric drill clamped in a vise and the wire is fed by hand (so the springs aren't precise) onto a mandrel being spun by the drill. My question is how can the required torque of the drill be calculated based on material/geometric properties of the wire. Does anyone out there want to give this a shot? Any help would be very appreciated. Thank you, Lucas.
Force/Torque required to coil spring around mandrel.

You are essentially asking how to find the minimal force which will plastically strain a specimen of the kind you are interested in., in bending. Given this force, at this radius of mandrel, allows the torque to be estimated, does it not?
