A lathe is kind of overkill, but it will work. Check Harold Hall's wonderful machinist pages for some tips. There is a plan for a simple end sharpener. You will need to set two compound angles, the primary relief and the dish to the center. He has a clever way of setting the primary relief just by using the height of approach towards a 6" grinder wheel. The indexing is done with a square index block. You will need one for each size of end mill unless you have a collet block.

Here are a couple of pictures of the tool grinder I built using the plans from Australia. If you are interested you can look them up at www.machineryplans.com == Jack

Now, just let me say. I was a machinist 25 years ago. It was the first (for real) job I had in the workforce. I did machine work for 5 years. Lathes, mills, shapers (believe it or not) and grinders. That being said, a lot of you on here are way above me. For sharpening end mills, I need something idiot proof. I'm looking for a "drill doctor" for end mills. 
Not that I don't appreciate your replies, I do, believe me I appreciate the help. However, I don't want to spend hundreds and hundreds and more. Building something is far beyond my skill set at this point and probably far beyond my machine's capability. Last week I figured out how to turn my mill on (it was a silly switch). I'm not ready to build anything quite yet. 
Although, post the plans in PDF if you can. I'll save them and maybe do it in the future. At worst, you help everyone else out. It's a win, win!

Seems like it would work for the ends quite well but I don't have a grinder and I don't see how you would do flutes unless I

CRAP! IT WAS 30 YEARS AGO! GOD I'M OLD!!!!Now, just let me say. I was a machinist 25 years ago. It was the first (for real) job I had in the workforce. I did machine work for 5 years. Lathes, mills, shapers (believe it or not) and grinders. That being said, a lot of you on here are way above me. For sharpening end mills, I need something idiot proof.

That fixture requires a surface grinder.
However, Here is a guy that didn't let that stop him:

We had a rig like Eddyde show that was used on a cylindrical grinder. The shop I run is getting rid of a cylindrical grinder, I think it will be surplussed at auction by the State. I got it running but being old technology it was taking up too much floor space.
I'll bet you could use a toolpost grinder.

Proper endmill sharpening is done with a cup wheel, not the OD of a regular wheel. I suppose a crude sharpening could be done the way shown in the video. But I would not expect the endmill to stay sharp as long as if done the right way.
