Tig would be best there
Not everyone has access to that
But it is really painless way
Just me sharing
yep, no quicker way to add an extreme amount of heat very quickly without doing damage to other parts....same shrink method can be used to "restore" cox cylinders but with a torch instead of welding. cherry red then air cool and you're ready to just the top of the cylinder and you can even get some taper.
