    Warner Swasey Turret Lathe

    Not mine. Note the M number makes it an antique

    No need for it, no space for it and no way to move it. But it sure would be cool.

    What the heck are those Swiss cheese things on the turret?

    Regards.

    You can mount boring bar type tooling, say as many as you have holes for, and do multiple operations in a single pass.

    Also... fat guide bars that engage socket on top of head stock (not present) to steady up turret in the cut(s)

    That is the "why" some of the "Swiss cheese" holes are so high up - to mount these bars

    Sort of an "over arm" except on a lathe - and in each turret station thought needed

    Normal extra heavy duty stuff 80 years ago.


    I knew instantly this was a big hole when I saw the photo of the headstock cast iron around the front bearing behind the chuck

    Edit in scan from one of their 1934 catalogs (lower right text block unrelated)

    This Swasey does not have them, but when were the telescopic way covers offered for the ways?

    Same 1934 catalog, which is for 1A/2A/3A shows them proudly in detail on two facing pages. Maybe this 4A USED to have them.

    I ran a 4A some years ago and remember the way covers. It was a nice setup and seemed bullet proof.

    Since you don't see big old WS that often, here are the CL listing photos for posterity

    And the other five. The listing states the spindle hole is 7 1/2".

    That spindle bore is really convenient and combined with the right chuck really makes this a great lathe.
    That slot in the front prism way really nags at me.
    An upgrade would be the rapid travel joystick and the missing way covers.

    Here are the way cover pages from the 1934 1A/2A/3A catalog

    Latest patent on this 4A is 25 September 1928:
