How can I remove the stub of a pencil zinc from its bronze anode
holder?

The pencil zinc screws into the anode holder. But the loss of zinc
from the anode means that I cannot get a mechanical grip on it to
unscrew it.

Cheers and thanks for ideas

Try a 'broken tap extractor' but if all else fails drop the whole thing in
some battery acid until all the zince has gone

Melt it out?
Zinc -419.53 °C, 787.15 °F, Bronze 950 degrees C

If the zinc is that far gone it is usually pretty fragile. Try
drilling the remains out and cleaning the threads with some small
sharp pointed piece of metal.

Put it on your checklist of things to do BEFORE they rot out that far?

I second the recommendation to drill it out, zinc is pretty soft and should
come out without too much trouble. Try an easy-out first and if that fails
just drill more of it out and then pick out the remains.

I did all of the things that have been posted here to try to salvage a brass
anode holder. I finally gave up and bought a new one at WM for about $5 or
so more than the zinc.

Yep... sometimes throwing money at a problem *is* the solution. LOL

Getting into a boiled egg can be tricky for some people..

I've heard it's quite cramped in there....

Leave it in white vinegar for a few days. Maybe needs new vinegar
after a few days if it's a large one.
