The Old One – Broken Tap Removal?

[Nigel Graham 2Participant @nigelgraham2]

NDIY –

Ah yes, I knew heat can speed a reaction though I had forgotten the numbers. Still, if room temperature suffices and time is not important, not heating it saves money!

The corrosion had not reduced the fragment much, probably only a few thou', but enough to loosen it further. It also removed a tiny " whisker " of steel that had prevented wiggling it out previously.

The stainless-steel was untouched save for a slight matting and change in colour, unimportant for its purpose.

Incidentally I once sectioned a worn-out injector from a miniature locomotive, and discovered that pickling it in mild acid neatly illustrated the cones and body as separate by their different grades of brass turning slightly different colours.
