sharpening end mills by hand.
#3
I hold the original angle as close as possible.
I think I might do it a bit differently though. I usually take a large flat stone and level off all of the bottom edges (just to get rid of aNY obvious damage). I then cut the angled relief edges.
After I get them all sharp, I run that large flat stone over the bottom again, staying flat on all the cutting edges. This levels out any higher or lower cutting edges.
Then I just touch up the angled cuts again until the flats I made with the flat stone go away.

It isn't perfect, but I've been using the same 3/4" end mill for a very long time to level off stock.

I usually don't mess with the flute edges, but I think I could probably touch those up as well if I had to. It just seems that the bottoms get dull faster than the sides for me.

I might have to get one of those diamond stones though. I go through those coarse knife sharpening stones pretty quick.
