Is it at all possible to sharpen 2 Flute end mills (HSS) at home on a bench grinder.

Yes, especially if it only involves sharpening the end. If sharpening the flutes, then yes, but nobody has the time or patience to do it as there are more productive ways to do things than to fiddle around.

Have a look at the thread I started called Grinding rest. You may be interested in something like that.

My old mentor used to grind the ends by hand. When somebody objected that it would be virtually impossible to grind them evenly he retorted, "One flute cutting is better than none!" Besides, he was probably skilled enough to get them pretty dern close to even.
