I have a pipe cutter. Would that work?

No, only one side of the pipecutter rollers will fit over the Copper bobbin.
That leaves the other side sitting in mid air and it won't work.

The Copper bobbin is actually very soft. Given any chance at all it will deform.
Using a metal tube with a slot in it to slip over the bobbin before clamping it in the lathe will work.
If you try and clamp the bobbin directly in the chuck it will deform, go out of center and the tool will grab and break off into the twisted Copper bobbin.

The Coppers very soft, and the where Stainless steel end caps welded, the welds very hard.
You have to use a parting off blade and cut a groove into the Copper, just inside from the weld.

Once you cut thru the Copper, its thin, the ends will nearly fall off except for the Copper rod inside, or the Tungsten rod, depending on which end you cut off.

I tried to use my tiny mini lathe, but I can only grab the stainless steel tube and as soon as the tool hits the metal it bends.
It will wait till I get access to a good large lathe, I have a 5 gallon bucket full of them.
