    I read your post and had some thoughts.
    Being able to precisely remove the material from
    your cylinder, as you have describe using hones,
    is unrealistic. By the time you’re done, including
    the seating of the rings wearing the cylinder
    smooth again its likely you have removed .002 or
    .003 from the cylinder increasing the bore size
    by .004 to .006. How are you going to make the
    piston bigger? Back in the olden days, when new
    replacement parts weren’t so accessible, knurling
    the skirt was how we compensated for this.
    I’m just another guy on the then internet so use
    your best judgement.

    Honing-
    The other thing people overdo is hone. They want to see a
    pretty 350 chevy cross hatch pattern but that is not necessary in
    our old engines. You are grinding away precious cylinder wall
    material. The extra piston to cylinder wall clearance will allow the
    piston to rock around in the cylinder and will break the seal of the
    rings. If you can’t resist the extra honing get a piece of emery
    paper and do it by hand. When your arm is tired you know that
    you are done.
