I guess I am doing a job where it would come in handy. We had to make two cylinder mount ends for some low boy cylinders. Customer did specifically say he wanted a lot of clearance for grease and rust.

Unfortunately, comachinist didn’t quite bore them out enough, and after welding them onto the barrels, they warped .030. And we did not verify the pins fitting ( we didn’t have the pins on hand to test fit) after welding. Delivered the cylinders to the customer, and when they found out the pins would not fit, they were a bit upset.

So now I am boring out an egg shaped hole to make a 2-3/8” pin fit. Only machine I have big enough is the big radial arm Fosdick drill press. I have a boring head setup in the #5 Morse taper spindle. Taking light cuts and praying the head does not come out of the Morse taper.

I do not have enough distance the way I am set up to take entire 10” long bore, so I have to do 5”, then turn barrel over and come in from other side. Hopefully I’ll get it close enough to get pin to slide thru.

Amazing how much a weld can distort and warp things. Unfortunately, this mistake was on us, especially since we did not verify the pin fitting after welding. No quick fixing this mistake.
I did make up a big centering tool to help line the head up. The drill press is not perfectly level, so it the head will move by itself before the column clamp locks down, making it hard to make fine adjustments. This way I can just pull the quill down and center it in hole, and then lock the column.

You obviously have experience dealing with scrap yards.

Experience has thought me it is best to have a good relationship with whoever moves the inventory and to communicate with them your intention.

Another hazard is having parts removed. Salvaging parts from machines is common practice at this yard. I have a good relationship with the whole crew there. They are keeping an eye on the machine for me.

Thanks to the link posted by digr I learned two things.

The machine weighs about 700 pounds more than I thought, but this indicated weight might be with an attachment that I see in the picture. It looks like an arbor support!

It started to sprinkle just as I was leaving the yard. I promptly covered it when home.

Here's a catalog sheet. Shows an optional outboard support.

Here's one that is a bit different - has a rotary tamle on the spindle.

Another: https://www.youtube.com/watch?v=Zl1xjG7IgkU

A couple guys at Practical Machinist have one. Perhaps one of them has found a manual or can answer questions you may have. Especially user KPOTTER (Kevin Potter). He's into vintage machinery.

You said this :
"Machines generally aren’t necessary to make anything unless they need to be made quickly.

It is not surprising that the skills of the hand are being lost to the believe that some machine or special tool is needed. There is little profit for corporations by promoting old skill values.

Corporations have been promoting speed and convenience for few generations now. The result is a loss of the skills that our predecessors have spent a lifetime learning, one of humanities greatest tragedies I think."

so "No machines for YOU !"

Because I like machines, especially ones that I can save from being reprocessed.

To be clear, my aversion to machines begins where the human element of control ends. I simply see computer control in any form as a disservice to humanity.
