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 .
