before i solder a bezel, i have draped a really worn 600 grit piece of sandpaper over the center of my sink and sanded the back/bottom of the bezel under water flow.
This way, the bezel is perfectly flat on the bottom too.

I was having this issue also until i remembered that i had to sand each plumbing fitting plumbing houses so the solder would flow easier.
Good idea. I keep a strip of 200 grit psa sc sandpaper stuck to a paint stick handy for the same purpose.

Thank you all for responding!

Dickb,

I'm using My-T-Flux from RioGrande. The torch is a micro torch. I think you may be right to think the torch and the amount of heat it produces may be the issue here. That is the only difference in how I do things between the small test piece and the actual production piece: size. The flame can't be controlled on the micro torch either. Today I'm going to get a small propane tank and try my new orca torch I got for Christmas. I really hope this will do the trick.   

Mirkaba,

yes, beginning to think that is the issue, will try new orca torch today.

Phishisgroovin,

I have made sure the bezel setting and the backing is flush and sand lightly before each attempt.

Hate being frustrated! Wish me luck today. I'll keep you guys posted.

You will love the Orca torch. I've had one for awhile and it works great. One caution on it. Mine did not come with the regulator for a one pound size propane tank, the small ones used with a camping stove, I had to buy it separately. Mine came with the regulator for a 5 gallon tank like you use for backyard grills.
As a soldering torch they are hard to beat and talk about portable. With the three tips you can handle most any soldering job. Good luck.

Good Luck. I am not familiar with the Orca torch. But I started out using the old blue hand held bottle torch and it has to be an improvement. I recently switched from My-T-Flux to Ready Flux and don't see any difference between the two. Both work well. I keep a bottle of Pripps flux handy for copper and brass. I got the Smiths "Little Torch" because I already had tanks and regulators for my "Big" Smith. :) I started out working with scrap silver from my girlfriends wire wrapping and broken jewelry from a pawn shop. Just played around melting and brazing and repairing until I got comfortable with it. Every new project is still a challenge though. I have a mental block when it comes to Bezel setting. Still have to get good (comfortable)at it...................Bob

Charles,
I was lucky, my orca came with the proper attachment for the small bottles. Ideally I'd like one of the mid'size tanks (4.9 lb) but for that one I will have to get a different connector.

Eureka!!!  dancer  Like I said, when it works, it's magic and that's how it felt. The orca torch is absolutely AWESOME!!! It finally flowed!!! ura It actually startled me because I didn't expect it to go so fast. With the micro torch I'd stand there for 2-3 min heating, heating, heating and watching the pallions oxidize. With Orca, I warmed the whole setting from underneath for a few seconds, started working around the outside of the bezel on the top and, poof, if just went. And truly, it formed a perfect joint, if I may so myself LOL:



It's amazing the difference the proper equipment makes. The micro torch has a very pointed, unadjustable, narrow flame and is good for very small jobs, but not for something bigger. I've learned some lessons from this project:

1.  As it is always said: solder flows towards the heat. And the heat it should flow towards is the metal you are trying to solder. So if it doesn't flow, it's the setting that isn't hot enough, not the solder.
2.  Do not put heat directly on the solder. If the setting isn't hot enough, it won't flow but solder will oxidize instead.
3.  Use the proper equipment for the job at hand! Ha ha, that should be a no-brainer, but isn't always obvious.

I was so happy last night, I was dancing! Thank you all for your replies and help. Now, to finish the job.

You did good!!!!! Yea.

The join is very well done. A little fire scale on the inside, but that could be from the earlier attempts. It's really hard to teach when your not standing next to the person to demonstrate technique and coach as the work is being preformed. U tube video's do a good job but soldering is a skill that needs to be developed by each person. Kind of like learning to ride a bike.

Your skills will improve and with each attempt it will get easier, the more difficult jobs will get finished and you will be able to call yourself a smith.

I'm glad we were able to help you.

Very good yes

I know nothing about an Orca touch. If it came with Smith regulators it has to be nice and pricy. When I use as a step up from a micro torch I use a cheep propane oxygen that I got at Rual King. It does work but the regulators  arnt very linear. Smiths have been on my wish list for a long time.

Happy for you

Bless

It is done!!! I was on the roll yesterday after the soldering success so just buckled down and finished it.  Very shiny and hard to photograph. There is just a light, bluish patina on it that contrasts with the gold rutilation. I did have to file down the bezel edge in some spots to compensate for the stone's irregular height. It turned out quite even.




Here is the back:

Beautiful. The engraved lines really do compliment the pattern in the stone. They will love it!
