  • When grinding a spindle taper, how do you inspect it?

    29/1/2015· When grinding a spindle taper, how do you inspect it? The horizontal spindle was a little battered from careless operators letting the pull studs hit the ID of the taper when changing tools. Didn’t look terrible, but when I put a test arbor in it I could get a slight runout on the arbor and I could wiggle it slightly, so I believed there was room to improve it.
