I've done quite a bit of soldering with stainless steel,
since most of my pushrods and my RDS hardware is SS.
I simply use acid flux, aka tinner's fluid, together
with ordinary soft solder and a normal soldering iron.
Nothing fancy. The acid flux is hydrochloric acid with
zinc chloride salt

hazard but then warn about fumes of unknown composition.

Hey now,
Maybe you're using the wrong flux? Rosin flux won't work, you need
acid flux to sloder to steel. Don't get your electronics close to it
though, corrosion city!

Gidday all,
What you are trying to solder is most likely stainless steel and the only
flux worth its salt is phosphoric acid. You will be amazed how well it
works on stainless or any other material for that matter.
A smidgeon on the end of a balsa stick is all that is needed and resin cored
Are you using rosin core solder...if you are that's it.you need to use
silver solder and make sure you are using the acid cleaner with it.

Are you using rosin core

I appreciate this. In the past I have used regular lead and tin solder
after having used an acid flux. It works well enough
In addition to the other comments you also need to be sure to use enough heat.
The steel pushrod must be hot enough to melt the solder.
The three big reasons why solder won't flow out are;
1. Not enough heat.
2. Surface not clean.
3. Wrong flux or not enough flux.

Silver solder that I am aware of requires a torch. Will the kit you are
talking about here work with a soldering iron? And is there a special kit
for the work we are talking about?
This one, from Tower, says it flows at 430 F.

Concur on the Sta-Brite kit. Often found in local hobby craft
shops. Worked great with the stainless tube push-rods (actually tubes)
that came with my Muller Esprit. Have used the flux with other solder on
"stubborn" joints too. Best to use an iron vice a torch, torch burns away
flux too
Again, try GOOP (Marine, Plumbers, Household, etc - they are all the
same according to MSDS), or Shoe GOO, or PFM. Create a small fillet,
submerse the tube apply some over the tube and let dry. Do prevent this
adhesive from sagging, wet your finger and rub lightly to cause it to
skin over.

Jerry,
Believe it or not regular masking tape sticks to those kind of pushrod
housing real well. What you do is to wrap the tape tightly around the tube
wherever you want to glue the tube and then glue to the tape. The glue
sticks good to the outside of the tape.
See Ya,
