step 2: honing I bought a cheap cylinder hone and wore 1 of the stones out doing the first 3 cylinders . how does 1 stone wear out while the other 2 look identical with hardly any wear ? any old school tricks for dealing with the ridge ? it's not much of a ridge but if theres a way to smooth it without machining the block then I'm all ears otherwise I'll just have to wear out some more stones LOL !
