Friends,
Much thanx for all the good advice, pointers and helpful hints! This is the
sort of thing that really makes this mailing list fun.
I'll be sure to post my boiler making progress to the list, once I actually
get to doing something. Given my usual speed of operation, it will likely

Hmmm. I'm not sure about that one -- I had thought that the cat litter
functioned like the firebricks, to keep the heat from radiating off the

Hello Everyone,
This is in regard to a previous message where I couldn't think of the mix of
gas that we use on our burn table.
I looked today and made two discoveries. 1.) The large stainless tanks are
oxygen. (duh! you can tell I don't use the burn table much, huh?) 2.) Propylene

Tips from an old weldor. NEVER ever attempt to use a torch on concrete.
Concrete will explode and send small pieces in the air and some usually come
in contact with body parts causing pain and injury. (I know this from
experience)

You might be remembering MAP gas, a common substitute for acetylene in the

The oil soak is cheaper (around here anyway).

I think I missed something, but the hearth is used for protecting your work area
from the heat and flame and to retain as much heat as possible into the work area,

You mean there's something other than cat litter to soak up oil?

Hello Everyone,
My two cents worth:
At my place of work (and most home shops), oil soak is much more prevalent
than cat litter. I've seen it used many times at described by Vance.
On the subject of refractory (fireplace) brick, you might have a difficult
time finding them anymore. With the
What about the Butane-Nitrous torches. Are there full size versions of
these? My hobby torch is super easy to use and I've soldered 45% silver
solder with it without a problem.

What a relief to see someone mention oxy-propane. I've been using it for
years, especially in the "home" shop. The soot from acetylene is not welcome
in the confines of domestic habitation. I happen to be using a Smith's torch,
very old but still usable. The oxy-propane is a little more difficu
Casey,
Ah something on this list that I feel a bit authoritative on. Having been a
jeweler and a metal sculpturer most of my life I have had one torch or
another in my hands. At present I own seven torches of varying uses.
If you are going to limit yourself to silver soldering boilers
If what you are going to do is medium size model boilers, then I would stick
to air-propane. After all, the cost is low, both for the equipment (you can
use a propane weed burner if you want), and the gas itself. However, if you
think that you might want to get into the larger models (say a 7 1/2"

there's no one at McMaster who knows diddly squat about silver-
soldering boilers. Bob's a terrific resource, and always willing to
share his vast knowledge with the rest of us.

Friends,
I'm tooling up to build a couple of locomotive boilers and am looking for
advice on details. I have already silver soldered couple of small boilers
using an ordinary hand held propane torch and a hardware store variety
