A good publication to get is TM 31-210 Improvised Munitions Handbook. Again, for reading purposes only, so don’t go out and break laws. Like I said, knowledge isn’t illegal, but making some things can put you behind bars for a VERY long time.
I hope that I’d never have to rely upon some of the things in that book, but there may come a time, so I’d like to have a general idea of how to do some of those things now should an event see fit to put me in such situations.
Again, use your head, don’t be an idiot.
As for the use of thermite in welding, yes it works extremely well, and could find a role in some SHTF rebuilding project.
