My father-in-law, a retired machinist, can sharpen a drill bit free-hand 
on a bench grinder in about 10 seconds.  He's done some for me and they 
work great.  Sometime I intend to have him attempt to teach me this 
technique, as I believe it would be a great skill to have.  
Incidentally, ENCO lists some drill sharpeners in their catalog, 
including a couple of small units which attach to an electric hand 
drill.  Anyone had any experience with these units?

I have a unit manufactured by a company called Martec.  Some new ones
are really cheap, mine has two stones, (one the "green" variety for
carbide stone chewers) and the collet is adjustable for bit angle.  The
only criticism I have is that the plastic collets fatigue and break after
a short while, and the plastic mount for the drill is pretty anemic and
failed shortly after purchase.  a large hose clamp now works quite well.
 I'm happy with my machine, it usually gives two equal chip strings after 
grinding.
  Having said all that, I haven't any Idea where you can get one :-(
