Anybody good at soldering?

[Howard Clark]

I'm with Jay. Ain't nuthin made of metal (except light white metal alloys) that can't be soldered. And even aluminum can be, it is just a royal pita and requires special stuff.

Clean the keys up shiny and bright (only necessary where you want to stick the solder), and then "tin" the place on the key where you want the pin to go. That is to say, heat the key, apply the flux, then apply solder to the bright area where the pin goes, and flow some solder onto the key first. Then stick the pin back on. And remember, when soldering the parent metal must get hot enough to melt the solder, don't just melt the solder. There's a lovely little "silver bearing" solder kit sold at most decent hardware stores. Little plastic tube with a coil of solder and the right acid based flux to use it. The silver bearing stuff flows at about 430F and will stick to most anything iron or copper based without too much trouble.

My apologies if you already knew all of this.

Epoxy is ok, and JB weld is probably the best of the easy to find ones.

Obviously my flux and solder combos aren't what they should be...I've had mixed results at best with anything but copper pipes.
