Ok, another HT member said he "silver soldered" a oem honda fuel line bracket and a steel AN fitting together. He said it fills in space and it won't leak.

Anyone know how to "silver solder"? What is used to do so?

 

Silver soldering is mostly silver with a little bit of tin in it, you melt it and it gets sucked into the pores of the metal. Its reasonably strong and can be used on dissimilar metals like you have there. Its not the easiest thing in the world and I'm no expert but thats the gist of it.

 

It's just brazing using a silver alloy.

 

some bike frames are made with silver soldered tubes, seems to hold up well enough.

 

So what is needed to silver solder??

 

brazing torch set and silver alloy solder.

 

where can i purchase that from??

Does a oxy/act torch get hot enough?? I seen those in home depot but with small tanks and they don't sell the refills like they do with propane. Who refills those small tanks with oxy/act??

 

An acetylene torch will get more than hot enough. You get the tanks refilled at a welding supply store.

 

Can get silver solder from Jewelery supply stores. Oxy torch gets too hot and usually the air pressure will blow your solder away. For something that small try using the accetylene with a small tip. Be sure to use flux. I'd like to see pics when you are done too. Also when using it for jewelry the real trick is making sure that your metal is not enough to bond to the solder. Not sure how that will work with metals you are using, I've only done it with copper and silver. Oh, one more thing, if they ask if you want hard or soft solder they are referring to the melting point of the solder and you probably want hard solder. Good Luck

 

Radiator repair shops use it to fix brass tanks. You can check there as well.

There is a link to a Home Depot version. You will need to get bottles, you can either buy or lease some from a gas supply shop/weld store and you can also get your silver filler from there. You need Oxygen and Acetylene. In the picture their is two tips, the one on the bottom not connected to anything is for brazing. Try setting your regulators to about 5psi each and go from there. It might help to get a book or something to get you started. IMO brazing is pretty hard, or at least to make it look good.

PM user Wes V and im sure he'll be happy to tell u whatever u want to know. That is Wes V's picture isnt it?

 

Yes its wes v's but i know he said he isn't on much anymore.....so i figured he wouldn't see my message anytime soon

 

He still signs on every now and then. He did a fuel line setup for me and its still in one piece. LOL. He knows what hes doing.

 

So do you have pics??

 

 

Go buy your local Hydrualics shop with a case of beer and they will do it for you.It is a effective method for bonding providing its done right.

 

same thing as brazing uses 5% or 15% silver brazing rod i got all needed let me know if ya need anything

 

the problem with silver solder is it does'nt bond into the metal......... no penetration it literally just sits there and hardens..........

IE not even close to the strenght of a weld, i would'nt count on that lasting forever. we silversoldered a hole in a compressor tank, and the pressure just blew it off.......

Well this isn't really needed for strenght..cause the fuel line goes into the bracket and the silver solder is used to fill the spaced to prevent any leaks!
