Kozo has mentioned in his books that he uses Sievert torches.
He has not, to the best of my knowledge ,specified a specific model.
Can anyone offer a model that would be used to build a
1 1/2" scale locomotive and a good source for purchasing one?
Thanks.
Wally

Hi Wally, I bought mine from Sulpher Springs (link below) several years ago, talk to them about what application you are using and I'm sure they will recommend which tip to use....John www.sssmodels.com/ |

I have 3 different torches I purchased in the past all of the do it yourself types, even the one that burns Map and OXygen. Propane torches are basicaly all the same it is the venturi for the oxygen that makes the diffence and of course the regulator. I have made 2 of my own for blast furnace puporses.The design can be checked out by searching for a Ron Reil Burner, I dont have the site on hand. But these could be modified for boiler building ( What I intend to do ) there is also a complete article " Make yourself a set of Propane Torches " by George Hill in the August 1977 Live Steam. This may be a little of the track of the original question However I find that there is alternative to sometimes expensive tools if one is willing to give themselfs the trouble, or that the budget is restrained. Just think you are going to make a boiler !! a little more complicated than making a torche, anyhow that is my opinion, in no way am I trying to convince anyone of anything, just sharing information I have acquired in my research in the hope it will be of use to someone.
Cheers,
IronMan ;D

For what its worth... In a fit of desperation I used my propane foundry burner, based on the Reil burner, for just that. And it worked great! I was silver soldering my "test boiler" made with 4" copper pipe with 1/8" thick walls. My hand held unit just didnt have the btu's needed to heat the mass of the boiler.
Good luck!

Thanks Alan,
I had in mind to make 2 modified version for when I get to making a 1.5" scale boiler. A lot of pictures I have seen of people making larger boiler, used 2 torches one is for heating the rest of the boiler so the heat does not disipate from the brazing area. I dont think that the Benz-o Matic type torch will be up to part on this one!!
Cheers,
IronMan

I work in the refrigeration field. We use 15% silver aloy mostly but use "silver" solder when joining steel. We use "Turbotourch" brand tourches. You can get tips of all sizes. It uses acetylene and air. It produces all the heat you'll need.
Just Google Turbotorch.

Thanks Jim.
I will give that search a try and see where it takes me.
Cheers.

Thank you for the site address. Looks like the web page took more effort than building the engine.

I used the Sievert 32mm nozzle size #2943 on my A3 boiler. You do not want anything smaller for boiler work. Propane/air and a large nozzle gives you the ability to heat a large mass like a boiler without it getting too hot at the flame tip. You will also want some smaller nozzles for smaller brazing jobs.
