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

For some small stuff I use an OA torch, my normal torch goes down to 1
cubic foot/hour IIRC range tip wise, this other torch starts at about
that size and goes lower. Fuel consumption is negligable so I don't
don't where you get $10 for 15 minute use. I'm in the UK and your price
seems expensive. Another option might be to look into a water torch,
they seem to be used by jewelers .
