What are the "preferred" gaps on a 3 roller grain mill?
Also... Are the gaps set before or after knurling the rollers?

So these gaps are obviously set tot the top of the knurl, right?
Yeah, It would be pretty tough to measure down in the gaps. The grain is getting crushed by the peaks and not the valleys anyway.

Do you have a punch or drill and small bit? If you can punch a small dimple or start cutting with the drill bit you know that it can be machined. It's not scientific at all but will give you an idea. Don't spend several hundred dollars in the machine shop building a mill that you can buy for 2 hundred.

Also, I work in metal fabrication and I am going to talk to the guy at the machine shop that does all our work to see if he would do the work for homebrew! Shouldn't be to much work. Maybe an hour or two a few nights a week. I operate SolidWorks. I will have it all laid out and ready to go when the time comes to make chips fly...
