Poor mans surface grinder

[The_Crusher]

Zip cut wheel on an angle grinder to cut them close and then put it on the mill to finish height with carbide. (Duct tape around each one as to not nick the surface)

Do not use diamond to cut steel as it would tear up the diamond. I seen a shop guy take a $500 diamond blade and cut some steel angles and the blade got wasted in a matter of minutes.

He meant use a diamond to dress the grinding wheel. You could throw a diamond in your vice to dress the wheel perfectly true to the spindle.
