Stopping tin solder from flowing?

Does anyone have a cure for stopping tin solder from flowing? We
have a moveable hinge that we try to solder in a hollow tube, the
problem we are having is the solder runs to the other half of the
hinge and freezes. We have tried talc, oil, milk of magnesia and
silicon, NO LUCK. Is there a miracle cure for this problem???

Rick,

Does anyone have a cure for stopping tin solder from flowing? 

I don’t know if it will work on Tin Solder or not but Yellow Ochre
will work for silver. My guess is it will work with the Tin but I
could be leading you off a cliff! :wink: I used to get it at Rio
Grande… no idea if they still carry it. A tiny bottle lasts for
years! Just warm the metal and apply it. It dries near instantly.
Then do the solder job. Let us know if this works… you made me
curious!

Good Luck. Dan.
