(2) In dialing in the crush, about how much of a gap in the plates should I start with before fine tuning?
(3) Will it be stable if I leave off the stinky rubber foot pad (smells pretty bad)? or does the smell go away after a while?
(4) Any other mods I should consider?
1) You can buy a standard bolt and cut the head off...and just simply secure the drill on the headless bolt. Or perhaps an easier soultion, and one I'm considering, is leaving the bolt head on, and securing a socket to the drill to drive the mill...or perhaps you could use a bolt w/ a female hex end, and secure a straight allan key to the drill...the advantage here is that when you need to mill, you just pick up the drill and mill rather than locking the drill chuck to the mill output. Best to bring the mill, or the handle bolt to the hardware store so you can be sure of the proper thread size avoiding a second trip.
2) Adjusting a corona type mill is usually best done by trial and error...perhaps start out w/ a credit card thickness and tighten from there untill you have absolutely no whole grains left in the crush.
3) The rubber pad is to avoid marring the finish on whatever the mill is mounted to, I don't use the pad and the mill is rock solid clamped to a piece of wood within the bucket.
4) as a matter of convenience, a larger hopper makes measuring grain and crushing easier.
IMO it is best to use a drill that has some b@lls. I have been using this one from HF that they often put on sale for 32 bucks.
See the ugly corona thread for all the info you could want in the link in my sig.
