Now that's a tool post grinder...
There are so many awesome things about that machine it is difficult to choose where to even begin...
I wish there was someone standing close to it for some idea of scale.
Flat belt drive. Somewhere above this is a large power shaft.
I like the pit afterthought for the larger threading change gears.
I wonder where it is now??? thats truly awesome. I want it in my tool shed!!!
tin roofing dies?
I was thinking Coragated Roofing dies as well. I'm not positive though. The size of the dies makes me wonder about something heavier. The next "Lathe" behind shows a new one in begining machining stage. I marvel at the process compared to today's machines.
these days tin dies are about 4" dia, these days we know how to do lots of stuff we knew how to differently long ago.
or they could be machining tires for trains.....:lol:

That observation is not far from reality. The good old day's before CNC...
Expanding the view reveals the tracer pattern, lower left of machinist's feet. The V has an involute-like form, so the stylus is radiused; smaller than where they converge, fillet where they meet parallel sides, and where those meet outer diameter. Many tracers are hydraulic only, depth controlled by crossfeed, first passes
don't create full contour. In mill profiling the cutter is most often ball end. Lathe work then, works likewise, with a radiused tip bit, either case is to scale of pattern and stylus. Roughing was accomplished by changing stylus or cutter size accordingly, as most patterns were 1:1, but ratios work too.
Since parting is still profiling, it's not uncommon to chamfer edges with same cutter before depth gets too far along, using the compound. best results are when [you guessed correctly] parting tool has small corner radii and square face.

nowdays it's almost like everything is disposable... or if it's been there long enough it's replaced with better and old sent to aisa.
That big lathe looks a lot like the Poreba I used to run once in awhile. Ours wasn't a tracer, but it had a 60 inch chuck and was 40 feet between centers, with 2 saddles. Attachment 37618
that would wear me out just cleaning every night.
We had one guy that never cleaned up. If he was making a LOT of chips, he always got the gofer guy to scoop chips for him. When I had to follow him, I always wrote the time spent on my card as "clean up after xxxx".
I remember those guys. we did have one machine that stayed covered in cast iron shavings.it pissed off the boss when he saw it ,till I explaned to him that is I leave the shavings there the machine wont rust...if I remove them it will...then I told him I clean it almost every day.as I was cleaning it before every use. when I left there after about 2o years that machine still looked good.a few months lator it was not quite the same..and somewhat. I miss running that shop...well I miss the equipment.

Oh - shoot.
??? WHAT??? NO TIC TOK DANCE THIS TIME??? IM SO DISAPPOINTED.:flame:
In an odd way, this explains equipment and PILES loaded onto adjacent flat bed carts, in the photo rather clearly.

a striper with no tic tok. what next? women with brains?:idea:
I'm honestly constantly amazed at the deep specialization of the hobby world. A store devoted to HO and N scale models of just steel mill equipment. The advent of 3D printers has been revolutionary for this niche.
(all the photos of the actual parts they sell look like they're resin-printed. )
where wood we bee with out them.

I like all the rollers...like snakes sticking their heads up to have a look to see whats for lunch.
Interesting too, swivel body casters not plate mounted or ball-transfers. Appears they swivel on each mounting post; and at least one seems to have a coil spring for height adjustment. Unsure how all those were leveled with shear platen, or extent how many we don't see.
Leveling would be fairly easy. Start at machine and work your way back while dragging a piece of sheet metal behind you. If it rolls from where it starts to where you need it, you're done.
