Thompson 1928 A1
Back in the mid 80s I purchased a
Thompson 1928 A1 (would be the Navy Commando Carbine model of WW2 style) from The American Historical Foundation and made at and by Auto Ord. as a Navy commemorative model. #25 of(300 ?)
I have recently fired it and stripped it to clean it.I very seldom fire this weapon, so have never stripped it down.While at the range the compensator keep turning about 15 degrees clockwise and I kept turning it back thinking it needed the compensator tightened. Consequently, upon stripping it,the barrel unscrewed easily.I also purchased a republished manual on the gun and it said(military copy) not to take down the barrel.
Is there anything I should do to assure the barrel doesnt loosen as easily?? (the manual said to tighten back up with a leather strap,so I bought a strap wrench at Sears to do this)
I saw where a person used Lock tite and was trying to borrow a tool to put his back together.Any comments??

Comments....yes; the barrel should not screw out that easily, and the use of a strap wrench is to tighten it without marring it--both of which facts I'm sure you already knew. As for Locktite threadlocker, you basically have two choices: red, which is just about a permanent installation as it requires almost 500 degrees of heat to break the bond and get it loose, and blue, which will release with mechanical force and basically just gums up the threads to prevent them from backing out easily. Go with the blue. Make sure that you thoroughly degrease both male and female threads before using, and use it generously. It would be nice if the class of thread fit were such that it did not back out, and you might solve this by trying a replacement barrel. I imagine, though, that yours is a high polish blue, and you will find most replacement barrels to be finished to a lesser polish that may not match the rest of your gun well. 0
