Soldering question...not plumbing related

Hello, I know this is not about plumbing but I have no where else to turn. I am tring to fix an antique pepper mill that is made of several different metals. there is an outer cylinder of brass and then an inner sleve (stainless steel) that is supposed to be fixed to the inside of the cylinder. I want to solder the sleve into the cylinder (it has become detached) but I don't know what kind of flux and solder to use, and don't know if I MUST have a soldering iron or if my blow-torch will do the trick. Any and all help is greatly appreciated.

solder

Go to a refrigeration supply store. I am not sure if there is any solder that will adhere to stainless, but they may have a low temperature brazing rod that will. It will need its own special flux, unless the rod has a flux coating. You will need at least a blowtorch, but even that may not get hot enough.

Solder

Also use map gas........

Stainless might need oxy-acetylene.

i also do welding

we use tri gas with our mig for stainless. try the brazing rod from weld supply . you,ll need flux also

That's what I love about this web site... an amazing amount of advice and knowledge is out there are people willing to share it.

Don't know what your pepper mill is - collectible, useable, valuable?? But my two cents worth as a DIYer - considering the complications obviously involved in soldering/brazing these dissimilar metals? Epoxy..........

soldering brass to stainless

I found an answer on the following site:

The Tin Man Respondeth

I think you will get both high strength and good appearance with a high (25% or greater) hard (high temp, 1100F) silver solder. Use a good flux, and make sure the metals remain bright and silvery during the heating process, as overheating will kill the brightness and hence ruin the silver.

Use a large tip, and a soft (quiet) feathery (carbeurizing) flame."
