For future reference: Brownell's sells a 56% silversolder in .030 dia and .005 sheet. Jeweller's supply places will have stuff like that too. They're handy for making small preforms when appearance is important. It's stronger than Staybrite, but requires considerably higher temp and the color match with stainless isn't as good because it has some copper in it.

That does sould handy, especially for oven heating.

I stole the harris stay bright solder out of my PM reseach kit and tryed some test joints. It seems to work well and with a little practice I think it will work for my project. Thanks

Be advised the 56% stuff can't be heated in an ordinary kitchen oven.

Your oven doesn't go to 1200 deg F? :)

I know, but someday I really need to learn how to silver solder so I guess I just got to keep on trying. I thought this was some of the easier (and more general purpose) SS, so I figured I should get an oz. to try out.

You will need different flux for the high-temp material. I like the black stuff.

Ask for the the black stuff because most beginners initially overheat the work and kill the flux. It also seems to work well on stainless.

A year or so ago, I ordered some silver solder from MMC and black flux because it was recommended in this group. Frankly I tried the black flux and I don't it much so this time I ordered white flux. The while flux was recommend by the welding company selling the harris silver solder too.

I suspect I got some learning to do!

It'll work fine if you watch your heat, which is a good idea anyway.

Don't we all! That's what makes it fun.
