    BAZMAK-Diary of a Myford super 7b lathe restoration

    Accurate Edge Finding ??

    Hi I Have not read every post so hope I am not repeating someone else, apologies if I do. In the late 60's and 70's I worked for quite a while on jig borers, typical tolerance +\ - 0.0002" max was probably 0.0005" occasionally a little wider on production stuff. However one method of edge...
