    Like this but smaller?:
    King 42" Vertical Turret Lathe - business/commercial - by owner - sale
    It is in California though.

    Probably more like a Motch.
    Used Motch Vertical Turret Lathe Mvsl 2 | HGR Industrial Surplus
    Used Motch Vertical Turret Lathe 125ts Vnc | HGR Industrial Surplus

    Better yet is a double CNC VTL with robot loader.

    Oh yeah, some of these animals run with the chuck on top, chips
    fall nicely into conveyor.

    If this is what you have a budget for, IIRC McKean Machinery had one or more
    of these, could be MAAG ?

    Yes a VTL but 100 a day is rather low numbers so other options could work at this level.
    Build tolerances less than .010 so easy to hit but the op has many flavors to contend with and I doubt he has build prints for them all.
    With a known family the op is well under 60 seconds. I have seen and tooled close to 100 per hour but that is fixed, know stuff in big operations and of no help to the OP.
    Not sure a robot load type thing works well for a place doing a hundred different part sizes and variations at this daily quantity.
    I would only go to mill as a last resort as in the only machine in the building handling the size and not in a hurry to get things done.

    I figured you would know what was going on. Some of the others might not fully understand. It's the slightly
    variable nature of the weld that complicates things a bit. I'm not sure if a fully automated process would get it
    right every time...

    I have a few tricks if the weld has made it "out of place".....

    Now the question....how accurate are they made ?
    Repeatability ?
    Yep, known as “joggled” tank head.

    Why not set up a small welding positioner with a plasma cutter so that they both start at the same time. Once you get the speed correct you should get perfect cuts every time.

    Plasma cutting doesn’t have a depth control. That joggled rim needs preserving.


    If the compound was set to the joggled rim profile, instead of straight in, that would help.

    I suspect the closest to automating the process is have the depth of cut incremented by 15 thousandths or so, by a tap of a screen/button, allowing the operator to turn their attention to a second (or third) lathe.

    I found a Jones & Lamson No 3 turret lathe.

    What do you think of this lathe?

    It has 11" swing over cross slide.

    108" long

    What your opinion of the gearbox,

    feeds, ect ?

    Tks

    I use a 16x50 lathe for cutting open T/C's and have a manufactured mount for the air ram.
    The lathe also sees use for other tasks so serves...…..Kiwi

    Is the ENTIRE machine 108"? Like kiwi said it will be useful for other lathe work also

    Gonna have to double up on JB Bergman, for a short, awkward piece like you are talking, a vtl would take up less floor space, be easier to center the parts, be a lot easier on the operator, probably be safer, just ... better.

    And I hate turret lathes .... they are cumbersome, heavy to operate, not that great for accuracy .... mostly what they are good at is hogging material and beating the crap out of operators. Man-killers don't lend themselves to high production numbers. This ain't 1943.

    I could get you a pretty nice new cnc one for about 50-60, or there's a bazillion old 24" machines hidden in barns.

    How do you see cut/chip.
    I mean is your head sideways?

    Does anyone know what the swing over the cross slid is on a warner and swasey 1420?
