jonister,
Used improperly the router can be a very dangerous tool. Its bits often moving at around 28,000 rpm. When you form materiel on a router you are shoving a piece of wood into the bit that is moving toward you. If that wood is not absolutely control some violent actions can occur. If insufficient downward pressure is not maintained the work-piece will vibrate and lift off of the spinning bit and if you hand is still moving toward the blade... gotcha. If the work-piece is pushed into the bit in the wrong direction, the bit will grab the work-piece and launch it violently into whatever direction it is pointed.
The standard rule of thumb that I've been taught and used is to keep your fingers 3"-4" away from the bit as you are moving toward the bit. If you have a small crankbait that is only 3" long that you have to both push into the fence or bearing AND hold down at the same time maintaining that safe distance is quite impossible with out some sort of jig to hold the work-piece for you. Now, you need to use something that is stable enough to still control the movement and pressure. A pair of simple push sticks like used on a table saw will easily slip and potentially be jammed into the spinning bit. (Insetr violent reaction here).
You could use a push pad like those for a joiner. That will most likely cover up the entire work-piece and you are working blind. Also, if the bearing on the router bit is too tall it will hit your push pad and not your work-piece. The shaft of the bit above the bearing is still a moving piece and could catch on the padded part of the push pad. (Insert violent reaction here)
Don't get me wrong, as stated above, I have occasionally routed small pieces of wood. Your fingers cramp up and you have to go slow. Not very good for production runs.
Below is a link to a video that shows just what a router can do to a finger that gets too close.
***Warning**** it is very graphic!
