    honing cylinders

    so i have the motor torn apart to replace the oil seals hone the cylinders and replace the piston rings. any suggestions on how far to go? i don't have a dial caliper at he moment so i cant get an exact measurement but when i started, the grooves in the cylinder were not deep enough to hang a fingernail in. i have made several passes and its looking better but i don't know how far i can go. i am using a mild to light stone so its not just grinding the metal away.
    thanks for any info

    I use a ball type medium hone and just get a nice cross hatch. If your nail cant feel anything then you have what I call false bernalin. You will be fine just make sure you put your new rings and check for proper ring gap.
