Dogmeat Dad, SASS #48563L Posted June 13 Share Posted June 13 Howdy, The title basically says it all, but I have a TTN shotgun that I have been using for a number of years and one of the firing pin nuts just won't stay tight. I have pulled the hammer and put a socket on it and tightened it as much as I feel is appropriate for a nut that size, but it typically only goes a couple of matches before it's loose again. I don't want to give it the full "Mongo" torque, but I don't want it to come loose during a match and lose it, the firing pin, and spring. I figure there are four options... Install a crush washer under the nut, but I need to make sure the nut fully seats as that sets the firing pin position. Crunch the nut a tiny bit to make it a "Lock Nut" but that will likely trash the threads on the receiver. Use a little thread-lock compound like LocTite 222, but I am concerned about it eating the bluing. Of course, there is always a lacquer like nail polish or the like. Anyone else have this issue? What was your solution? Thanks in advance, Dogmeat Quote Link to comment Share on other sites More sharing options...

Abilene, SASS # 27489 Posted June 13 Share Posted June 13 Hey Dad, my old TTN has always done the same thing, right side only. I think I tried some sort of thread locker on it at some point, but I just remember to check it before each match. My right side plate screw likes to come loose, too.

Dogmeat Dad, SASS #48563L Posted June 13 Author Share Posted June 13 (edited) Larsen, I was hoping you would pop up with the answer. I was going to put a dot on the barrels under the wood forend as a test, but now I can just do it! I was about to grind a perfectly good box end wrench to be thin enough to fit without removing the hammer! I'm sure that would have been exciting! LOL Thanks!

Colorado Coffinmaker Posted June 13 Share Posted June 13 PLUS ONE for Larsen E. Blue or Purple LocTite are your friends. DO NOT TORQUE it. Torque is NOT your friend. That Chinese steel is quite soft. Strip the threads and you'll have a fine Wall Hanger Quote Link to comment Share on other sites More sharing options...

Torque is NOT your friend. That Chinese steel is quite soft. Strip the threads and you'll have a fine Wall Hanger Yep, I can feel the softness of the metal. Had me thinking of how to fix it if it stripped. A new nut could be made, but the other would require drilling out the tube and making an insert to replace the original. Could be done, not easily, but it could be done. Got me to thinking about an oversized nut and an helicoil used backwards. Hopefully, it will never get to that point. I blew a brake line on the truck (During Thunder Valley Days of course!) and have to make a run to Home Despot to get a new small pipe cutter as my old small one it lost in the garage somewhere. When I finally die, my kids are going to be cleaning out the house wondering why Dad had 10 of the same dang tool! I will pick up a fresh tube of Blue Loctite222 while I am there. Last one is probably 20 years old and, you guessed it, lost in the garage somewhere... 1 1 Quote Link to comment Share on other sites More sharing options...
Rooster Ron Wayne Posted June 15 Share Posted June 15 Never had that problem with a Stoeger. I would suggest Blue Loctite. Rooster 1 Quote Link to comment Share on other sites More sharing options...

Blackwater 53393 Posted June 18 Share Posted June 18 Schoolmarm says I’m a loose nut with a tight grip on the wheel!! Yeah!! Blue LocTite!! 1 Quote Link to comment Share on other sites More sharing options...
Dogmeat Dad, SASS #48563L Posted June 18 Author Share Posted June 18 Well, Sunday night I did the deed. Cleaned and prepped the nuts (more like I flange bolt with a hole drilled through it) and the mating threaded hole in the receiver. I also discovered that there was a bur on the end of nut that kept loosening which may have prevented it from seating fully. Buffed that out with a jewelers file and stone. Used a toothpick to carefully apply the Loctite to the threads of the nut, and snugged it up. Did both of them. Next match (and the first test) is this coming Saturday near Williamsburg, VA, Smoke on the Mattaponi, then Black Gold, then Gunfight at the Double C, then Appalachian Showdown, and then hopefully, North Carolina. Not doing too many monthly matches at the moment, life is too complicated these days... Thanks for the info, I will report back occasionally with status. Hope it works! 6 Quote Link to comment Share on other sites More sharing options...
