Propane + air silver soldering small parts?
I used to make jewelry as a hobby and I made a lot of it.
I used a Prestolite torch and did very well with it. However, there is one best way to go and that is with the Smith Little Torch (changed ownership now) and a "B" acetylene bottle and either a small oxygen bottle or a propane bottle (if Smith makes propane tips) and you will be set. In fact, I am very surprised that many folks on here and the sci.engr. joining group don't have a Smith Little Torch I darned near would bet money that once they saw one in action, they would rush right out to complete their welding repertoire. j/b " wrote in message ... I have a few propane units .. some are large hardware store units that I use for heating saxophone parts. But I need a small cheap propane and AIR or that uses AIR not Oxygen (way too expensive $10 for 15 minutes is tooo much) to do silversoldering on small parts. I mean real silver soldering that is high temperature and results in high strength attachment as in saxophone parts like keys that I want to make. There is a type of solder with silver in it but I mean 1200F melting temp solder that is almost brazing temp. ..any help here? I have tried the sax forums but they have not been very helpful for some reason. I have BernzoMatic TS4000 ..puts out a lot of heat but flame is way way too large ..can I get smaller nozzle to fit on ti ... I have tried but information is lacking. This unit mixes air to give the right heat but too large a unit. Also BernzoMatic 370A to use with TX-9 container Also Bernzomatic MPS gas and oxygen bottles with small torch The best solution wouldd be the above TS4000 with a smaller nozzle for a smaller flame if anyone knows where or how I can obtain such a unit. thanks a lot Frax |

It is ok with detatched parts but too large to use near the body of an instrument. LLLB |

You can get tips with flame size so small you have to use a magnifier to set the mixture. Haven't had to use the smallest tip in the set, yet, just put it on and fired it up one time to see what it did. Just a small blue dot. Have to use a flame to light it, a sparker won't do the job. They also had a full range of tip accessories at one time, including bendable extension tubes in 6" and 12" lengths and ring burners that had three flames converging on the center. That's great for brazing tubing and fittings. Also had dual tip burners with the tips opposing. Don't think they're cataloged anymore, kind of specialized. Got mine before they disappeared. Got to be quick brazing copper or brass with O/A, it'll melt or boil in an instant if you're too slow. Stan |
