Owner Change/rotate spark plugs?

If you're talented enough! Don't forget your torque wrench, new
gaskets and antiseize compound.

Copper gaskets can be annealed by heating red hot and quenching in
cold water. They can be reused three or four times this way until their
diameter gets too large from being squashed. Using used, unannealed
gaskets can result in small leaks, and a leaking plug can carry carbon
into the threads and make it really hard to remove without damaging the
head's thread socket.

That's how you harden them.
To anneal them, heat them red hot and let them cool gradually.

No, copper is annealed by quenching rapidly.

OK, you got me there. As it turns out, copper may be annealed by aircooling
or quenching. To harden copper requires a temperature decrease of about
10,000 degC per second which isn't going to happen if you drop 'em in water.

By the way, you'll never get copper hot enough to anneal with a propane torch.
Oxy-propane, yes.

WRONG!! Copper behaves the same way as aluminum -- quenching from red
hot results in softening -- not hardening.

Steel wants to cool slowly to soften, though.

Ah no.....Orval was 100% correct.

And you're posting this during a discussion of the question whether or
not an owner can change their own plugs.

So that means that means that wheher the gaskets are annealed or
reused without annealing is irrelevant? That the owner wouldn't benefit
by knowing about using new or annealed gaskets? Come on.

Well, I have learned from elsewhere in this thread that NEW gaskets are DEFINITELY the way to go since there is
debate as to whether the proper treatment of used gaskets is to include cold water quenching or ambient air
cooling...
