Interesting link that.

I've just had a quick google, and one of the first hits was Cutting Force During Milling - CNCzone.com-The Largest Machinist Community on the net!
Which for a 1/4" cutter gives a maximum measured force of 700N.

Now taking Torque = Force x distance = 700N x 0.015m = 10.5Nm

Which isn't quite high enough to totally kill my simple idea, but would involve a stupidly powerful motor, so back to the complex idea.
