The 6” Craftsman metal turning lathes (made by Atlas) had 1”-8
spindle nose thread until 1959 when the Craftsman changed to the
Timken tapered roller bearing headstock. Then the spindle nose
changed to 1”-10. From 1940 through 1958 the Craftsman 6” lathes
had the bronze bushing headstock. The first Craftsman 6” metal
turning lathe which came out in 1938 had a 3/4-16 spindle nose.
You are correct stating that the Atlas 618 lathes always had
Timken bearing headstock with the 1”-10 spindle nose. This is
based on a review of Craftsman catalogs that I have on pdf.
