Sorry for such a newbish question.

I picked up a cheap corona grain mill and also got a great little dewalt drill for christmas. I notice a lot of people have their mills setup with a drill and am hoping to do the same.

How have you done it? Is there a certain size chuck I need? My mill handle is threaded (It's a Victorian).

you have to find some way of driving it - usallly a bolt of the right size. go find the Corona ugly thread - tons of info.

I don't use a Corona mill but I imagine they're all pretty similar. What we were able to do was just unscrew the crank handle and then found a bolt at the local hardware store that had a allen wrench head and just bought a little allen wrench bit for the drill. These aren't the bolts were using, but just an example I found on google.

Just make sure you get the same type of thread and make sure you're not driving the mill faster than it's supposed to go.

It's metric. Close to 5/16", but metric. Take your handle bolt to the hardware store and get the correct sized bolt, then drive it with a drill and a nut driver attachment. I have much better success with my corded drill. My high-end portable drill is no match for my cheap corded drill...

when your grain flies ALL OVER THE PLACE, you have the right speed

There's pictures of the shaft end of coronas in my thread.

Mine came with a shaft already put on the back where the handle used to be, as you can see it is just a piece of metal rod. Many folks use a threaded rod instead, and I would highly recommend it as you will have more grip for your drill shank to attach to it.

Threaded Rod. Go into a hardware store. Pull dollar out of pocket. Buy rod.

I went this route as well and got me a metric bolt and cut off the head.
Theoretically it should work fine, but in my case, my drill was not all that strong, and couldn't handle the workload. I nearly burned it up. I have reverted back to using the handle until I get a better drill.
