Can you use a food processor to grind grain?

We want to start grinding our own grain because it is healthier. Can you use a food processor instead of the hand cranked grinder or the expensive machine grinder?

The motor is not strong enough to do an adequate job. Check ebay for a Bosch brand mill, they will run about 250$. It’s a bit pricey but worth the investment. Bosch also makes a mixer for making bread.
