You now have a drill bit clamped into the vice dead center of the spindle. Put the shaft into the drill chuck and tighten. Drill out center of the shaft.
The shaft spins, the drill bit remains stationary.
Take care, plan out all the steps, make sure that the shaft can be placed into the chuck without moving the vice and drill bit.

Thanks for the suggestion. Now we have two.
Your method and teched3's:
"You could try a drill press, drilling a hole in a block of plastic or aluminum with it securely clamped on the drill press table. This hole would be equal to the shaft diameter. Then change drills to a small center drill, and then step up increments to your final hole size. Not perfect, but will get you close."
