Sometimes I just use a .45-70 Government for cleaning. Then go buy a new one all shiny and pretty that actually works.

Hey, I was where you are until one evening when my wife (a food scientist) said, "Put it in the freezer". I replied, "Honey, that's the opposite of what we want to do! Everything will contract and my frozen Poseidon DIN bolt will be even tighter!"I never use...that ridiculous put it in the freezer system

She said, "Trust me."
So I did, and I video'ed both the first attempt at removal and when I tried again after overnight in the freezer (since this was in preparation for one of my repair seminars).
Night and day difference. Maybe 30+ Nm and the breaker bar wouldn't budge the connector. I was afraid the hex key was going to damage the broach.
Out of the freezer, and it loosened with less than 20Nm. Piece of cake. I've got it on video, and play that every class.
Everything contracts. The bolt gets smaller, and on the outside, the reg body contracts, too. But it doesn't contact around the bolt. It evidently contracts away from the bolt, microscopically speaking.
It's my first trick, before I start throwing the whole reg in the ultrasonic, or four days of dripping Kroil penetrating oil into the threads. It doesn't work every time, but when it works, it's amazing.
I'm not sure that's entirely accurate, and it's one of those concepts I always struggle to fully grasp.[...]
