I've got a 15mm SS nut and I want to braze a (SS?) hex wrench to

But I don't weld. All I've got is one of those itty-bitty MAPP
gas torches, some bronze and silver brazing rods, and some
brazing flux for each.

Is there any hope of getting a decent bond that way?

Intended use is on the water - so I'd rather not determine
whether it will drop off or not experimentally.... -)

I'll crosspost this to a home repair group. There might be
someone who can answer that there. I do a little welding but
not professionally.

I'm no welder, but I've done some welding and brazing over the years.
I've never heard of brazing stainless steel. It could be possible, but
I have my doubts. If all you want to do is hold the nut in the wrench,
I'd just JB Weld it in there. If you want to be 100% sure it dont come
loose, take it to a professional welder. They have special equipment
for SS. Even if they charge $50 an hour, it will probably take no more
than 10 minutes to put a little weld on it, so I doubt it would cost
more than $10. Another thing would be to get a piece of SS about 1/4
thick or more, drill and tap threads in it. You'd probably need to make
a bend toward the bottom end. But that would probably take more work
and cost more.

Whenever I have to weld anything other than steel, I just let the
welding shop do it. They have the equipment for SS, cast iron,
aluminum, etc.
