As far as placement of your mill, the ideal distance is probably around 150ft or more away from any buildings of any sort. If you can barricade it that's even better (things like sandbags). Just make sure you don't block off air to the motor. When making black powder there is always a chance for it to go off.
The steam options requires a large pot of boiling water and a false bottom. Put the grains in a large grain bag and set it aside. Then bring the pot to a boil. Once you had a strong boil going, place the bag over the steam rising from it for about a minute and a half. Then pulled the bag out, stir it a bit and quickly mill it.
