I just want to solder silver jumprings

I've searched, and the information is overwhelming. I just want to know: can I solder silver jumprings closed with a soldering iron? If so, what kind of solder do I need? And if not, what is the cheapest possible way to do this? The jewelry store will charge me like $10 per, and this is unacceptable for my purposes. This is for small silver charms. Doesn't have to look perfect, but I also don't want to poison myself. [more inside]

Can I stretch out my light bulb?

I have a candelabra chandelier (E12) and I want to use LED bulbs in them. The problem is, the bases of the bulbs are so wide that they bottom out in the socket before the bulb's end pin can make contact with the bottom of the socket. The socket does not have a tab I can pull out, and the chandelier is made in a way that replacing the sockets does not seem very accessible. I have encountered this with two different brands of light bulbs, and looking around, it seems that it is a common problem with LED lights. So, I want to stretch out my light bulbs. [more inside]

How to turn my line out into an external speaker out?

Wiring/music equipment question: I have a fairly cheap 30WVox guitar amplifier with a phone/line out jack on the back. When I plug something into the jack, sounds stops coming from the amp's speaker and starts coming out of whatever I plugged in instead. However, I would like it if the sound would come out of both at the same time. How easy or difficult would it be to rewire the amp so that it works this way? I'm good with a soldering iron, but not too great with circuit analysis.

Should I eat -- er, solder -- this? On the aging and toughness of ceramic disc capacitors.

Should I eat – er, solder – this? I'm building a preamp and I just discovered that I'm low on 0.1μF 50v ceramic disc capacitors. My question is about whether it's worth trying to salvage more from another (already disassembled) piece of equipment. [more inside]

How to get a new cable soldered onto my mic?

I managed to slice most of the way through both the rubbery insulation and the copper cable on my stereo condenser microphone. Don't ask me how (I'm a total idiot). Is there somewhere I can send it to have the cord (miniplug stereo) replaced? I realize it's basic geek task, but I'm not quite confident enough myself. And I have zero idea where to send such a thing to be done. I could just solder the existent cord myself and crimp it, but that wouldn't work 'cuz the mic gets lots of rough use.

Superglue conductive?

Is super glue (cyano acrylate) electrically conductive when dry? or wet? I just finished soldering something, and the joints are very close together. I'm trying to figure out if it's a good idea to coat everything in super glue to better insulate it.

What soldering gun

GuitarTechFilter: I have purchased some replacement pickups (humbuckers) for an old Les Paul. Rather than paying the $60-80 bench time to have the local music shop do it, I was considering doing it myself. In order to do this, what kind of soldering gun do I need? Any particular gauge/weight of solder? What else do I need in terms of equipment to pull this off? [more inside]
