Take a look below at the topic "Rounding Crankbait Bodies" and scroll down to the post about the "Aussie Wheel" by Hazmail. It's a custom contoured wheel with sandpaper mounted in a grinder that he uses for rounding over. About the only thing left beyond that is a duplicating lathe, which suppliers of unpainted balsa blanks to online stores like lurepartsonline.com or Janns Netcraft use. Unless you're a "tool freak" or intend to sell crankbaits in volume, the cost of a duplicating lathe may be impractical.

If you're building with a softer wood, a carving knife, or even a sharp exacto knife, should remove enough material quickly to reduce the amount of hand sanding.
I use an oscillating belt sander, which has two different diameter drive wheels at either end, and I can get my lures shaped and rounded pretty quickly with it.
I use a small vibrating sander to do the final smoothing.
I don't worry about exact symmetry. I just check them by eye.
I also don't mass produce lures, or I'd probably make one of Pete's grooved sanding wheels to save time, and increase consistency.
