SPECIAL AND NUMBERED STONES
If I need to touchup a seat after machining, even on the Serdi, I go to my numbered stones and holders. I have three numbered holders and always use them as pairs. Sometimes if I just need a quick touch up and the stone is good, I won’t need to dress it. If it does need dressing it will generally take less to clean it up so less dust. I keep dedicated stones for different heads I work on regularly and it speeds up the job. I just did a 466 JD and had the correct stone, so the touch up went fast.
