Torque/force calcs. for coiling wire around mandrel

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.
