Oh bugga, Ian.  :palm:

I would go with the stud and threadlock idea, to stabilise the remaining threads.

I have used Loctite 270, for many years.
Even for steam engine (exhaust) pipe joints, and hot air engine displacers. Never had a failure........  :thumbup:

Loctite 270 is down to less than half it's strength at 150 deg C and the makers don't push their graph beyond that temperature !

I'm sure, they used to quote 250 deg!

I've used it for many years, without problem.........

Everyone. Make your own mind up.  :thumbup:

They quote 250 deg C as the temperature to raise it to to break the joint

What sort of temperatures is the cylinder likely to reach?
