Hard enough that it wouldn't be recommended for the home shop.

A better question would be why you'd want to do this.  Stepper motors are mass produced, easy to source and really not that expensive to purchase.

A very basic motor to demonstrate the principles could probably be quite easily made.  There are a number of very simple DC motor projects on-line and a very simple stepper motor would not be any more, maybe less, difficult.

Most outrunner styled BLDC (brushless dc motors) can be converted to work as a stepper motor  / servo if you wanna go the route. A outrunner can be made by hand or just pick one up from a model shop.

Inrunners work equally well (and no moving parts on the outside)....but expensive

How complex and efficent motor do you want?  If you are just looking for a demonstrator, this works:



The motor is more accurately described as a variable reluctance motor.  the rotor is just steel - no permanent magnets.  15 poles on the rotor times 4 coils give 60 steps per revolution in full-step mode - perfect for a clock if the coils are energized at 1 second intervals.
