That tool posted in the first post doesn't remove metal so I have no idea how MM is doing what they claim with that tool.
I have a Lisle precision cylinder hone like that hone, Sunnen makes one and I'm sure other good tool company make them and sell them also. I have removed over .0015 taper from more than one block with a torque plate mounted on them

Their is a knob on the top of the hone to put pressure on the stones, the more pressure the quicker the cutting. Lisle and Sunnen offer different grit stones also

I quit using mine long ago due to the time involved to get the job done compared to paying a good machine shop to do it on a commercial honing machine
