Default Brazing vs Silver soldering

I want to do one or the other for some simple music wire landing gear. Which is better? Is either easier than the other? I have some brazing rod with flux coating and would use my butane torch, or try and use the torch with the silver solder. Thank You in advance for your opinions.

Use fuse wire binding and soft solder. Brazing or silver soldering will take the metal beyond the critical temp and the wire will harden and break on the first landing.

I gotcha on the soft solder. I have the copper wiring. Would rosin core solder be considered soft? If not, recommendations, please? Thanks again.

Yes, electrical solder and plumber's solder are considered soft solder. Either should be fine provided that you make a good mechanical connection before soldering.

Stay Brite is abetter solder to use as is contains a small amount of silver. so it is stronger than regular solder

Just make sure you wash the flux off after soldering. The rosin core wont corrode, but most other solder fluxes have acid in them and this needs to neutralised. I use a quick wash with boiling water...

Radioshack sells a solder called silver bearing solder. It has a higher silver content than the typical electrical solders sold. Needs a good high temperature iron but is much stronger that most solder types typically available.

if you need an easy way to stop the solder, just take pencil and mark the area that you dont want the solder. you can solder/braze up to it and stop. but you can force past the pencil mark if you really want.

Hi!
As has been said earlier...brazing or silver solder will not work on piano wire as it softens the steel rod.
Best metod is to use sweet solder and reinforce with some kind of thin wire, copper or steel.

Best solder to use is "Stay Brite" as it contains a flux that makes soldering soo easy (very corrosive) and a solder that contains silver which make the soldering joint much stronger than ordinary thin/lead solder.

Most plumbing solder has silver in it now, as they are trying to remove lead from our drinking water. The better plumbing solders have a lot, and require much more heat. Read the label for melting points.
