The Cardas is just beautiful. Easy to melt, good active flux that's easy on the surfaces, wets readily, leaves a clean shiny joint, just the right gauge for electronics (though a little skinny for, like, speaker wires). I've been building a lot this last year, and I've hardly put a dent in that half pound spool.

Listen to ya Unca Poinz; go on down to the sewing store, and get a lump of beeswax. Make sure it's real 100% beeswax. With your iron, sweep over one flat side of the lump, and stick it to your stand, right next to the sponge. Not too close to the iron holder, now.

No cheating, each and every time you pick up the iron out of the stand, touch it to the wax, wipe well on the sponge, and give it a little tin with the Cardas. Perfect joints every time, and no overheating of the circuit.

Prosperous New Year, guys,

Poinz
