    Stripped Screw and JB Weld

    Tried the JB Weld trick with a stripped out frame screw. I've let the allen wrench sit inside the JB Weld while it cures for up to two days. Everytime I twist the allen wrench, the JB Weld just snaps like plastic. I'd drill out the screw or cut a slot in it, but since it's the frame screw, it's in kind of an awkward place. Any ideas or am I using the JB Weld improperly?

      Around 24 hours. Should I wait longer?

        Dear God I hope it isn't the 12th Man Mag.....

        Definitely let it sit for more than 24 hours. Also, try to make sure it isn't in a humid environment.

        I know it's hard to wait it out, but more time equals a tighter bond (to a certain extent).

        I had a stripped ASA screw (recessed, so cutting a slot wasn't an option) that I was using the JB Weld method to remove. Three times I had the JB Weld break after 24 hours of curing time. Finally, I set it up and went away for an entire weekend. When I returned it came out without any problems.

        Give it a good 72 hours in a warm and dry environment. Also, make sure you are using the largest possible wrench that will fit in the screw (A torx head is preferable).

        Good luck and don't worry, you will beat that screw. Just don't let it frustrate you. Frustration = scratched up marker.

          No. An old classic that I'm trying to clean up.

            Rob it happened to me on one of my emags. To cut a slot into the screw use a hacksaw blade (without handle) and tape around the part you hold with your hand. Use a fine blade and cut in the forward direction with minimum downward force..

              Just to be sure, you are mixing the two parts in the JB Weld 1 to 1, right?

                That is the screw that connects the knob of a CP ASA to the body. Extractor bits shredded the brass and failed with flying colors.

                It was such a great feeling when I finally got that out. I swear I have NEVER seen a screw with more red LocTite. They must get a nice bulk discount on it at CP.

                    I have to go to the hardware store tomorrow, so I'll pick up a hacksaw blade as a backup.

                      That's a GREAT picture! I have hope now.

                        I dremeled a slot in mine and still could not get it out. I resorted to some Kroil Oil and a center punch. If you put he punch on the outer edge of the screw head and tap it down and counterclockwise, it eventually starts to turn. Since the head is already gone, it's not a problem as long as you can stay off your frame.

                          the screw is more than likely a buttonhead so itll be hard to tap it off. if the jb doesnt work, i dont know what will. ive got a brill bit set that has a set of hex heads. ive got the regular sizes and than a set that has the same sizes but just a little bit bigger. theyre probably metric but they work great to remove stuck screws. i tap the head in with a hammer and then just twist off.
