I plan on getting a dressing tool. Do i want one of the spiky wheely  
things or a diamond tool?

I have several tool grinders, but i was worried the runout would never be  
good enough for the diamond wheels or i could not mount them precisely  
enough. I would not know how to dress a diamond wheel??
