[time-nuts] Tin Can Soldering (was Wenzel Oscillator Repair)

[Robert Atkinson]

Hi, Wasn't following this one "real-time" but there is a useful trick used on aircraft instruments wit soldered cases. They put a ring of tinned copper wire in the joint before they solder it, leaving a "tail" sticking out. Next time you want to open it, you just pull the wire out (cold) and it brings the solder with it. It also provides a good surface and heat spreader when you are soldering. The aircraft cans have space left for the wire, but many pressed cans have a radius that helps or push the end in below flush.
