Some messages on this thread mention a butane-propane fuel mix. Is it safe
to be using a fuel with propane in it for our models? Ever notice how heavy
and thick the metal is on a propane torch fuel bottle? Propane has an
enormous vapor pressure (around 200 psi at room temperature) that

Well, I don't really think there's that much danger in it (or I wouldn't
have tried it!). If you have two or three gallons of water, that's as
good as having it surrounded by sandbags. That water is going to
absorb a _lot_ of kinetic energy.

Anecdotal evidence follows: I have used the butane/propane mix (gaz) upon the
recommendation of Sulphur Springs, in COLD weather only. During warm weather, using
only iso-butane, I made a run with the messy Steamlines Shay following my friend
Ted's porter he built on a Roundhouse boiler/drive.
I found Iso-Butane at REI backpacking stores in Oregon.
This fuel is for MSR stoves. MSR stoves are distributed world wide, so I expect most
backpacking stores have the 6 oz/ 170g cans. Sulphur Springs markets an adaptor for
the fuel cans.
I believe, but did not record and do not remember, that
There have been a number of discussions about butane/propane mixtures.
What I am hearing is that there are quite a few people using a 80/20 and
70/30 camp stove fuel with great success. I read some where on one of the
message boards about a gentleman in Florida that did a lot of
Thanks for the pressure test hints Vance. Do you have a similar way to test boilers?
I have a metal scrap yard close by with lots of copper tubing...
If the tank is full of fuel and ruptures, the force is channeled and abated by the
water bath, but the fuel would escape into the air correct?
I'll gladly draw up and post my tank design, if anyone is
interested.

I suppose I should note that this tank requires silver soldering; don't
think that ordinary soft solder will withstand the pressures. (It may,
but I don't think so.)

Vance,
I concur with your design completely, but just want to add my two cents
worth. For ultimate safety the stay should be made of phos-bronze. The
Does anyone know what pressure that the gasket on the filler valve will
fail? It seems that this might be something to consider in the tank design.

I have been given what I think are the parts for a Steamlines smoke

Can anybody please help with advice, or preferably a sketch or image

Thanks

Carl, in theory no. In practice, I can state that at least one of them
went to approx. 200 psi and did not fail. Note that, using a
All Right - who of you out there is using Tiag Machine Tools (lathe and mill)
and what do you think of them?
The mill has a fairly good write - up in the new Garden Railways.
I bought a Taig Lathe (and all the tooling available, including the milling
attachment) 26 years ago. I was 13 at the time and it took forever to save up!.
I have made countless parts and can highly recommend it to anyone who needs a no
frills, low cost setup. On the Taig, working to precision
Hi, folks,
Mike Martin wrote me the following note, kindly offering to share a

Casey,
I think nearly all of us have used the propane mix at one time or another. My local
supply is now 100%
butane and here in California
Mike,
Looks like quite a gas tank. In what order did you braze up the pieces, or did you
just rely on capillary action
to hopefully "wick up" the solder between the joints surfaces?
