Tools to peel and crush a whole garlic bulb
I built a little wooden impeller for my food processor that hits the cloves hard enough to peel them, but not hard enough to gouge or break them: 
The center piece is an old dough mixer blade for the food processor. The wood is maple; pine is too weak. The rubber flaps on the bottom, screwed on, keep the cloves moving so they'll collide with the wood.
I've peeled as few as 2 cloves, and as many as 4 bulbs with the device. Peeling takes about 30 seconds.
It works best if you separate the cloves from the bulb before starting. I just cut the bulb end off and pull apart.

If I want small bits of garlic afterwards, I just use the food processor's cutting blade. Otherwise a rolling pin should do a good job of crushing en masse.
