a Dean Smith and Grace will weigh a few tons, and that is for a small one.
The one we have is 3 tons for a 17X48... The chip pan is cast into the frame... lol

Here's another one...

Smaller lathe... One that I want with an Imperial/Metric screwcutting box...
There was a very cheap mint myford in the YVR CL last week. likely family selling the old mans prized lathe.
Yeah, crazy capability, made to a great standard!
Way outta my league to move and keep though. Monarch was REALLY generous when they started hanging dimensions on their lathes. Understated to a fault, with the capacities well over the other machines that shared the same designation. Not cheap with the cast iron, not cheap with anything!
A friend of mine has a slightly smaller (CK model, IIRC) Monarch, and it would not be a good lath to use for chambering in the headstock, as the headstock is longer than many barrels. Kinda hard to set up a spider in the middle of the bore!
Great machine, and you could not by similar made today.
Gonna need a crane over the bed, or room for a forklift, to load and unload, though!

Could possibly make it work to chamber through the headstock with something like this to hold the barrel...

I've seen this lathe in person... it's in incredible shape. Almost new shape except for faded paint. If I had room, I'd grab it in an instant... But it's a big MF...
Man I dream of having a machine like that for my "cannon" hobby, my 1440 Taiwanese hobby lathe is a good machine within a "non-commercial" realm but workpiece size limitations limit my "hobby enjoyment" . I do have room for that Monarch but have no where near the power source it would require.
Gonna have a heckuva time adjusting it while the barrel is stuck halfway down that long bore.
Short answer. No.
But with a bed as long as that, it isn't that much of an ordeal, to set up the muzzle end in a four jaw chuck and use a steady rest.
Otherwise, you have to come up with a means to adjust the barrel while also sorting out how to measure the runout, all while working down the bore of the spindle.
Sorta reminds me of the joke about the Colo-rectal surgeon that rebuilt the car engine through the tailpipe, that!
Seems a lot harder to do than it should be!

While I understand what you're saying, I think there's a bit of a disconnect here... This device is about 8" long, and sits flush with the face of your chuck. You put your barrel through it, and you have screws like a spider in the front, middle and rear. If you're taking light cuts to cut the tennon, shoulder, and thread the barrel and chamber it, it should hold just fine. On the phone, the guy and PT&G told me that it eliminates the need for a rear spider until you get the barrels large enough that they'd engage the spider anyways... Bonus is that you'd be able to do all your adjusting near your measuring gauges anyways.
OK, looking at it hard, I can sorta see that. Maybe.
They don't make much of a compelling sale pitch there on the site. Sorta thing you wouldn't really look at twice, if you didn't already have a solid idea how it works or why you might want it.
That said, it's a tube with some tapped holes in it. Make one.

amosfella;13021940[B said:]I think this may be a bit oversized for you cannon hobby[/B]... It's about 10' between centers. I'd guess it's north of 18k pounds. Get a 3 ph enclosed gen set and go for it. Those gen sets are going cheap right now.
Nope...gives a guy room to "expand" his horizons, mmmm you know a replica of one of those WWII "Howitzers" might be intriguing and I think I have a piece of h/w pipe 8 ft long laying in the shop that is close to 105 mm bore......should have never come close to this thread.
