Today I attempted to sharpen a ITW 2 flute endmill using the surface grinder. I used a vise, V block, shims, and a magnetic base stand for a flute index. I got the primary grinds, gashes, and center relief dialed in. It was very pretty and sharp, but I the primary edge didn't have enough center relief so it rubbed.
I have the Harold Hall book about TC grinding, and am familiar with the jigs he has made, but what are the jigs you folks use for endmill end sharpening? I am not in need of center cutting geometries, or flute grinding. Just to touch up the ends and reuse endmills with chipped corners. I have a jig in mind but would like some ideas from those who have done this regularly.
