...
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

You can get the little B or MC bottles from any plumbing, HVAC, or welding
supply.

If you really need a lot of heat, get this tip.

That'd be my suggestion as well - one of the top two outfits on that
page, depending on the actual size of the parts. Additional larger or
smaller tips are inexpensive. I think the Swirljet tips would be
unnecessarily harsh for the intended use.

A MAPP torch like this would probably also work, but nowhere near as
well.
