Useless advice.

But near enough the same as all the other *practical* people on here have
given? But it's nice to see you've taken my advice and started to deal
with simple things.

If it doesn't move, then use a blowlamps and heat the
copper around the old immersion. This expands the metal and the brass
immersion slips out.

You'd have to expand it a long way before the immersion would 'slip' out.

You forgot, physics

Maxie, it is best you stick to the soldering iron in your enchanted
workshop.
