I have ridge reamed several engines and 3 stone honed, re-ringed and re bearing-ed, back through the years some are still around running good. I have a craftsman I bought in high school, back in the late 80's.Best way is to use the ridge reamer properly, 3-finger hone, then finish with a ball if you want it to look pretty. 3 finger does a better hand job than a ball because with some firm pressure you can straighten it some.
