end mill sharpening
SPiN Racing:
I have the Sears Craftsman utility sharpening tool.
50 Dollars US, and it has a green stone, and a resivoir.. so I simply pour distilled water on it till the stone is staying wet, then adjust the rest, and then gently work the tool.
The wheel was NOT TRUE when I got it, but it moves so slowly, that its not really an issue for me... and a buggered tool bit that you need to remove a lot more material from is nice to help get the wheel more true by keeping it in the high spots with more consistant placement. A little interrupted cutting took the high spots right down. Once down I simply helt the carbide to the wheel at what I felt was the right angle for that tool and let it slowly grind the shape.
It makes a very nice smooth crisp edge.

SPiN,
It's a bit difficult if not impossible to do endmills free hand. You need to hold the tolerences that are in the thousands from one cutting edge to the next.
End mills are usally sharpened on a cutter grinder. I'll see if I can find some pics to post of one.

This may or may not be of use but in the book MILLING A COMPLETE COURSE
there is a section in the back for making a grinding rest with plans and instructions for use
and how to modify your bench grinder for cup wheels.
according to the text you can grind the end and the side cutting faces
I bought my copy from here http://www.play.com/Books/Books/4-/356418/-/Product.html?searchstring=milling+a+complete+course&searchsource=0
