The Washington Post article from which is comes refers to it as a turret la
the (2/3 the way down the article, and just a "lathe" elsewhere) in this ob
ituary on "Rosie the Rivetter". But it looks more like a milling machine
with a rotary table than a turret lathe. Is it a gear broach?
Anybody recognize it?
I don't think it's a lathe of any kind. It looks like a
special-purpose bed-type milling machine, built to handle that big
rotary table. The drive shaft suggests that it's a production machine,
but it looks like she's locating the setup with the handwheels -- for
an operation that could have no possible relation to the powered
shaft. Here's a sharper version of that photo:
I question whether the photo is of a real operation, or whether it was
cooked up for the photo. The reason I say that is that there's a gear
fixtured on top, and a toolholder that looks like it could be for a
shaping operation. But the toolholder doesn't look like it's holding a
shaping tool. And there's no way, in wartime production or any kind of
production, that you would cut a gear like that with a single-point
cutting tool making straight cuts. Even if you did, one of the
handwheels would have a big and obvious index-pin dial on it.
The whole setup is screwy. The lathe chuck on top, on top of all of
that fixturing, looks like a kludge. There is no way you'd use a chuck
that way for gear work. And if the suggestion is that she's indicating
or gaging a gear tooth, there is no apparent
way to accomplish the measuring. And that is no freaking measuring
I'd give it four Pinocchios. d8-)

There were multiple Rosies, one a local NH woman:
It looks to me like a lash-up to broach an oddball keyway or splines,
unless somone just placed the gear atop the jaws for appearance. I
suspect it was chosen for the photo to show her face next to something
complex and exotic-looking that wasn't in use, covered with oily chips
and spewing them toward the camera.
First, that Tiny URL I posted above doesn't seem to work. That's the
first time that's ever happened for me. Tiny URL seems to have a
problem with the full URL. Here's the full one:
It's physically possible that it's set up to cut a keyway, but I still
don't believe the setup. It's an awful kludge. And if it's intended to
cut splines, how is she indexing it? Finally, if that's figured out, I
hope she's not in a hurry -- it's not like there was a war going on or

Spam your own group instead of spreading your insanity all over the
web. You claim to be the grown-up; prove it. Thank you.
That was just a reply to something that came from whatever group
you're posting from. Did you also post this message to the poster who
included your group in the list? No? And why not?
Pay attention to the headers. I didn't post the spam.
I think it is a shaper. The tool looks MUCH like a shaper tool, and seems
like it might be held in a clapper box, although it looks kind of different
from what I'm used to seeing. If the setup is the way it was used, and not
just something thrown together for the photo, then she would be cutting a
groove in the FACE of the gear.
Whoooeee! That's a right nice lookin' machinist. Hubba hubba.
Naomi, if you were Rosie's inspiration, ya done good, girl. RIP
It looks more like a vertical shaper to me, set up for gear ID
slotting. (not that I'd know anything about either, yet. ;)
There were vertical turret lathes:
I bought a transmission-end motorcycle chain drive sprocket for my
sawmill and then discovered it has a 13-spline center hole, that I
couldn't index to groove the shaft. The final milling setup using a
52-tooth Sears AA lathe change gear was about that kludgy.
My opinion is that it is a slotter and the machine is set up for
making a gear. as there ar no chips around, it does not depict a
production situation, maybe a photo op of a nice looking female next to
I'm no help with that one. I only know it from texts too.
Metal working stuff is my hobby line. I was an electricians apprentice
for several years while studying radio electronics. Worked as a two-way
radio, printer and terminal tech for most of my career. We probably
know a lot of the same jargon in those areas :)
Images 3, 5, and 7 are for a different machine than the rest. These
show 3 controls on the front while all the rest have only one.
I think you nailed it, though.
Is "slotter" one brand's name for "shaper"?
BTW, when did you start top-posting? I noticed it yesterday.
That's it, all right. Now, what was Rosie doing with the handwheels?
She's not indexing it; she isn't even looking at the indexing
handwheel. Is she eyeballing the rotary indexing and the X-Y
positioning? Unlikely, unless the bore of the gear has been marked out
on a surface plate and she's setting it up to cut to the mark.
But if she's doing that, how does she know that she's set up
perpendicular to the centerline?
Once again, it looks like a photo op.
