Well, those fan motors turned out to be very inspiring! I ripped one apart and the insides were very simple. Stator with a few coils that were easy to see, plenty of steel laminates, and a rotor consisting of what looked like a bunch more steel laminates.
I removed the fan blades from the rotor and connected it to the power drill. This generated a little AC power! This was the first time the multimeter needle moved without me shaking it. I then took the magnets I had taped around the wooden block and re-organized them so that they fit inside the new stator setup. I spun these and noticed even more of a twitch in the multimeter needle! SWEET! (and that's with ten little ceramic magnets!)
The next step was hooking up the rectifier. That was only a matter of rewiring a few things since it's just a little rectangle with four terminals. When hooked up to the multimeter this time it produced DC power! It peaked at about .4V ... about a third the voltage of the dead AA battery I found. This is all very awesome! More to come...
