Try sticking them (the neutral weave) all into a big blue wire nut.
Fan the two hots to the left and right.
Then wind the neutral with your cordless drill and a nut driver tip.http://www.licensedelectrician.com/Store/RT/Nut-Blaster.htm
The big blue wire nut grabs the stranded wires sweetly, the drill provides the revolutions. The wire nut is backed off/ clipped off before the neutral is landed the usual way.
The drill motor should be pulsed -- for torque and control.
With practice, you should be able to perfectly create a stranded conductor in the field.
This gambit saves on the wrists, too.
(Omitting the big blue wire nut means trying to stuff all of the strands into your chuck. Good luck with that.)
