I know lathes in general - not the Hardinges. I have a nice Sheldon
that Dad and I bought together as a young boy.
When little we had three boarders renting rooms (very large house) and using
one side of our 100'x100' shop. They made steam engines that took heavy duty
four wheel trailers and a commercial truck to pull (early 50's).
I had the pleasure of meeting one of them four years ago! Still a machinist,
he was top notch - working for special defense projects. Now retired.
If I knew 1/10 of their knowledge I could write books.
If we get more inputs and insights - we might be able to sort things out.

Martin, do you know these Hardinges, as it seems? Can that guy talk to
you perhaps? He is a super guy, NRA and whatever.

Just thinking.
Was it shipped in with the "Half nut lever" engaged ? And the end stop or
tail stock was run up against it ? or it on the Headstock?
Is the Feed clutch in drive in/out and the cross slide is at and end ?
e.g. is the front lead screw turning for some reason ? Not a basic function.
The spindle might be dry and heats up. The pop might be a bushing expanding
or the like.
Didn't say that the machine stopped when it popped.
More input is needed.

Motors have end bell red buttons.
Some might be just internal. I had some that way.
Might be a current sensing unit in a power I/O box.
I have no idea what the control looks like - mine is a barrel switch
and a motor with belts and gears.
Many are electronic speed control in a lathe foot or cabinet.
Thermal breaker has a push out button. It pops.
I wasn't there so I can't say if a Klixon clicked or that was the
back gear that was jammed and the friction drive was used with to much
back force. [ Klixon is or was a Texas Instrument temperature switch
of high quality - bi-metal plate that flexes and that might be the pop.]
Rather hard to diagnose since I have not seen one or touched it.
Can you say were the pop came from ?
Any more input ?

Sounds to me the Hardinge is running. The pop is likely a
re-settable temp
thermal breaker. An overload is present. I don't have one.
We couldnot find one, and also why would it pop???
Is there a back gear lock engaged ? spindle lock ? shipping that way ?
No. It spun just fine. And then, click -- and it stopped.
I would hope a Hardige owner / user would step in .
