I hook a cordless drill up to it.  That works well as long as you remember to charge the battery beforehand.

One of my generous friends gave me an old motor (u can get one off a clothes dryer ) and I set it up on a found kid's desk and got 2 pulleys from Grainger +belt to slow the usual 1700 RPM to 180 which is what most mills use..too fast a grind could burn the grain if a long term run

I got away from using the double-pass method, but I may have to revert back to see if it improves my efficiency. I doubt I'll ever use the "wet" milling method with my current setup, but it's easy to see how that could improve your numbers. Thanks for the post!  ;)

A good way to check the gap on your mill is to use a feeler gage. They are typically used to check the gaps on spark plugs and can be purchased at automotive stores.

But if you are looking for a rough check using common household items, the following can be used.

crisp dollar bill = .005"
standard credit card = .030"
standard 1" paperclip = .034"
dime = .057"
quarter = .070"
nickel = .078"

The coin thickness are measured at the rims.
