I use one of these:

It works well. The container hold lots of shavings and you can see when it's getting full.

The name has the word "school" and word "pro" in it. What more could you ask?

(It doesn't cost $100, so I'm assuming this isn't the $100 wonder sharpener that broke.)

The man wants to build something! We can't go discouraging that!
Some other ideas for motors could be windshield wiper motors. They run off of a 12V DC supply which might be an additional issue, but I'm sure they could take a beating. Also, check out allelectronics.com site under motors, they have a ton of motors of many sizes there. A lot of those are DC, but there are AC ones in there too.

As for connecting the blades, I'm really not sure about that. I guess I just can't see the blades so I don't know where to start. Belt driven or direct drive is about all I can come up with. Or a direct drive system with those worm drive things would let you place the motor and blades easier.
