This is on the money. Those usually also come with excellent bits to fit every type screw perfectly.
With a few years in machine shops and millwright welder I've got a couple other tricks up my sleeve.
The more time you've got the more gentle you can be with it. BE GENTLE with that impact driver and BE GENTLE with that torch. A propane torch is plenty to ruin the heat treat on that barrel. Using the impact driver you can use the pen oil and the driver together making sure there is always oil available to the screw threads with any minuscule movement and just tapping the driver repeatedly. Over and over and over more times than I want to type if you have the time and set it aside to soak intermittently.
There are two types of Locktite, red and blue. The blue is probably what they used if they used any and it is intended to release with heat.
Just the tapping and the use of a hair drier is enough heat if you do it repeatedly eventually it will just move and you'll wonder if it was ever tight. The temp changes between the screw and the steel around it will "suck" in that oil a little each time it warms or cools.
