You should be able to just clamp/chuck the wires into the drill like you would a drill bit.i've never done this but i assume its pretty simple. just get three wires of the same length. make sure all 3 wires on one side is held together with some tape and make sure to tape it onto a hard to move object (desk/) and the other side of the 3 wires be taped onto the drill with some more tape then just turn on the drill.
there could be an easier way to do this but i came up with this from the top of my head so try it if you want.
yeah cut how long the wires need 2 be... put one end in a vise or get someone else to hold them tightly... and put the other end of the wires in your drill like you would a drill bit... and twist away
