content: way more complicated then I thought, you need special hones , I thought the spring loaded ones improved hole geometry but they are just for bore surface smoothing (I thought it was decoupled on an axis so it would grind out a perfect hole with respect to centripetal force, literature says otherwise).turns out drill hole works fine lol, but I did step it up from every drill bit in the kit to 0.75 inches, better to just rest it on the face from a end cut on a lathe I think then to try to align it in the hole given there is very little force on the indicator post (so I actually made it loose by a few thousandthsseems to work ok)

content: Spring loaded hones are often called "deglazing" hones. They will just follow whatever hole geometry that is already there.

content: do they have hones which align with axis of rotation?I am unclear if a 'hard (superabrasive) hone' is a device which uses centripetal force for truing or if its more like diamond covered reamerhttps://www.sunnen.com/graphics/assets/documents/4c4ce4585729.pdf

content: Not sure what you are asking here. Are you wanting to know if the hone can shift the location of the hole? Certain honing setups can do that but most of them just float, so that wherever the existing machined bore location is they will center on that.

content: I imagined that they are like a cutting tool thats almost on a gimbal, so its radius depends on the axis of rotation and force pulling the things outwards, and that it would tend to improve hole geometry in generallike, that they would eliminate error in the hole from the drill press shaft and drill/reamer bending due to downward pressure, and possibly even eliminate some error if the drill press trueness to the base.is not perfect (because of gravity), but I guess its a far cry.So that a 'bow' from non infinite stiffness would be corrected/alleviated (perhaps it would make some kind of 'flower' polar-coordinate figure based on 'bouncing'. ?does the hone very well follow the axis of the drill?Like a cutting tool that is somewhat decoupled from the axis of rotation by gravity so long the base of the machine is set so that its perpendicularity is greater to the gravitational force the to the column (easier to adjust a flat bed with a spirit level possibly then to use concentricity (after maximizing concentricity with a indicator)? gravitational correction or something like that
