I milled an armature using a drill press, But as Finn says,
I don't really recommend it. I didn't have an x-y table, so I just slid
the work around by hand, but the end mill had a tendency to jump to
the side at times due to the flexibilty of the drill press shaft. One
time I thought the shaft was definitely bent, but It seems to be OK.
It's a good thing the shaft is pretty springy.
I've also used the file method, and especially for an armature that
gets 4 flats, it's quite easy and fast to do (about 1/2 hour as Finn
said), because the flats are not that deep. I have no special training
in the use of a file.
I've also used the angle grinder method, but this went very slowly,
possibly because the grinder blade was somewhat dull ( I had
borrowed it from a friend), and because it was a 2-flat motor, so
I made the flats deeper.
