button/switch repair

[FreeTheArmy]

i have a few OTFs. the Piranha Excal., the Microtech Troodon, a Microtech Ultratech Clone (all black, stamped with an airborne symbol on the clip), and a 7" italian OTF (some sellers call these the small Sinatra).
the 7" i've had for years and years, it's a fun little toy, and was hoping for it to be the first to hand down to my kid. however...
the button has detached from the internal mechanism. i removed the front scales and soldered it back on which held for about a week (maybe 20 times open/close).
the solder is not holding. i've gone through a few types of solder short or silver. but perhaps there is a metal bonding that will be more secure?
i saw a material to material breakdown review of the DKW Sandshark. the narrator stated that the small springs attached to the locking mechanisms were held in-place by a bonding agent.
anyone know this bonding agent??? or perhaps have a suggestion?

What about JB weld?

[FreeTheArmy]

JB weld... I've never used it. I suppose its worth a shot. Thanks!

[FreeTheArmy]

JB weld. wow. i think i've fallen in love. thanks leighdog. perfect suggestion.

I admit to using JB on lots of things, but never a knife. A couple months ago I patched a hole in the oil pan of my truck with the stuff.

[FreeTheArmy]

Well, I've seen my old man use it on a few things around the farm, but nothing this small, just a wheelbarrow, a pot belly stove, and a freezer door.

Its great stuff.

JB Weld? A tube? Never heard of it....

[whippersnapper]

Tom, it's a 2 part epoxy kind of stuff. The original comes with 2 tubes (hardener and steel resin). Mix equal parts together and it sets up pretty strong. There are a few different kinds including one called waterweld that is supposed to work in water.

It can usually be found in the automotive section in stores.

Fantastic. i use JB all the time, for all kinds of stuff, but wouldn't have thought of it for repairing an OTF spring action. great suggestion.
