Reuss, my apologies....didn't realize the audio in the video link would be difficult for you to hear well enough to understand the speaking. The interesting older gent being interviewed and being the tour guide is Jay Lehman, founder of Lehman's, and restorer of many of the items they have on display.

Here is a transcript of what he said in that clip:
Jay:
When you put pipe in the ground, and you have flanges on them, and you bolt them together. Then every so often you put a valve in there so you can shut them, and the valve comes down in there like this, at a taper. And then that there machine here -- the different sizes are to resurface the seats, so when the valve comes down there -- it resurfaces it so it shuts off right.

Interviewer:
So it sits in a groove?

Jay:
Yeah.

Now, do you s'pose there could be someone around there who very sneakily moves those explanation signs around to confuse visitors/customers/tourists....and then stands back watching and listening and GoPro recording peoples' various reactions....kind of a private Candid Camera type amusement to watch at home for hoots and giggles?

Now, about this other thing:
I tried to give the Get-Out-of-Jail-Free card to 'The Man', so I could be out and about, again. He took one glance and fumed,
"What?!?! You think I'm some antique or somethin' ?!?! A 2MB card ?!?!"
(He was really fumin', and gettin' louder, veins poppin' out all over -- neck, forehead, ears, eyelids... gettin' redder than raw water buffalo meat...he prob'ly could'a lit his cigar on the side o' his cheek!! )
"You think I can operate my warp speed, uber-MP,
poly/titanium/mirrorless/shutterless/errorless/noiseless/diffractionless/artifactless stratosphere-glamor level genius camera on an ancient 2MB card, and expect me to let you out with that ?!?! What? You can't count to 512GB, or what ?!?!"

I think he's gonna make sure I'm double-shackled in the chain gang, and I'll just haf'ta settle for hopin' I'm in a good spot to hear the calliope tweeting along when that train goes by.

Yessir on the oilers....some homemade varieties on some of those, too.
Keep the wick-type from getting dried out, too, or some ctitters will try to eat the wick. I was really quite young, probably before old enough for school, so I don't recall exactly, but I believe it was turpentine that one old fellow used to keep the wick rosined up, so a couple of his hogs wouldn't eat whatever they could reach of the wick, even when it wasn't getting dried out.

Sippy, it's designed for external on the flange faces, as you mention, but it also is made to work the internal seat faces for the valve gate, as well.
See the step at the outer end of the platten?.....right side end of the vise looking frame in the upper part of the case.

For flange faces, the valve flange is set in the platten in the lower position so it can make those faces parallel.
For the tapered internal seat faces, the flange is set up on the step at that outer end, to set the center shaft that few degrees off the center line axis of the valve bore, so the die will work the tapered face. With the bonnet unbolted and the shaft, handle, gate and all those parts removed, the die is inserted in place of the gate, then the internal seat faces can be worked.

The ratcheting part of the die setup can be worked in that throat where the bonnet was removed, with about as much ratchet travel space as you can see it has where the dies are stored in the case, as seen in the pic Reuss has at the beginning.

Modern facing/dressing tools are pretty much electric- or hydraulic- or pneumatic-powered ring motors to rotate the dies.

For any slightly interested, but not familiar with the valves, this is pretty basic, not worded super-technically.

This is a slightly different seat configuration, usually with harder seating surface material for reduced wear.

Oh......just one more thing....
Reuss, don't overdo your modesty on getting 'national attention' for Lehman's.....you are probably getting them some international, worldwide attention. I mean, UK, Argentina, Phillipines, New Zealand, France......gee willikers, how many places have people been who took a peek at what you presented?
If Lehman's internet sales go up enough because of this, they may recontact you to drive up to their place several times per week to help them process orders.....never know.

I'm impressed, I think you got out the entire last two paragraphs without taking a breath. And don't forget that one Aw Shit cancels out all the atta-boys you've collected.
