Greetings, I'm a new member.  I purchased at auction a number of older steam toys which I am woefully unprepared to operate.  In particular, I'd like advise on what type of fuel I should be using for a medium sized (24" long) Case tractor and where I might be able to acquire the needed parts.  I'm aware that most of the steam toys are powered by alcohol or flammable pellets.  The items I purchased seem to be set up with gas burners.  I am attaching a couple of pictures of the Case tractor showing a threaded metal tube extended out the back.  The tube connects to what I assume is a gas burner sitting under the boiler.  I'm guessing that I need a pressurized gas cylinder with a flexible gas line to connect the canister to the tube.  Is this familiar to anyone and can you lend me any advise in putting it into operation?

Many thanks,
Tom Sanborn

Welcome from Minnesota! Very nice model! Looks to have been built with a Stuart Turner engine.

You can find gas tanks here (maybe built a little water cart and hide it in inside) :

Gas can be bought in the camping sections of stores, Butane or Butane/Propane 70/30 mix.

Not sure if you want to say where you're located (guessing US) but there might be a member near you that could help you get them going.

Thanks Nick!  I'm located in Santa Barbara CA (but please don't hold it against me!).  I'd love to find some folks in the Ventura/Santa Barbara/Goleta area that could give me some direction with my new toys.
The Ministeam tanks and burners look great.  I was concerned that my existing burner might require more gas than their tanks can provide.  The connection on the back of the tractor is a 1/2 20 threaded connection.  It looks like the Ministeams are closer to 1/4" so I assume they are designed to deliver a lower flow of gas.  The tanks look great and I'm sure that one of them could be mounted on the rear deck of the tractor.  In that case, I would need to use a short flex line with reduction fittings to connect to the rear connector.  Alternatively, I could replace the existing burner with a Ministeam tank and burner set up but I have some concern that modifying the existing tractor too much might be consider blaspheme by people that really know these machines.  I have a couple of old cars and people cringe every time I use something that isn't an NOS part.  I also need to find some 1/8" flex tubing to replace some of the deteriorating tubing that connects the boiler to the the engine.  Is there a source for tubing that can handle the heat and pressure?

Thanks again for all your help!

Tom

A bit too far for me to travel, but I would have loved to have come help! Clevedon steam is another great site for parts, you can screw these valves right onto the disposable camping tanks, run that up to your existing burner and pull it behind on a trailer.

I wouldn't worry about modifying this tractor as it is a home-built (but very nicely done)

I missed where you asked about new flex pipe from the boiler to engine. I would highly recommend going with a new copper line soldered in place. Easy to do, but if you're not comfortable I am sure there is some type of model club near you with someone that would help.

Thanks.  I'm not uncomfortable with soldering but not sure how it's done with copper tubing.  I'm familiar with using fittings to join copper tubing (I'm an architect) but want to learn to do it right with solder.

First, what a beautiful traction engine. You have done well!  

Caution though, this hobby is highly addictive!

There are lots of good tutorial videos on YouTube for silver soldering. That's what I recommend if you want to give it a go. But, find some material to practice with first!  Silver soldering takes patience and practice, but will give you the best results.  The most important thing is to get solder with a high silver content. The common solders available from the big box stores is ineffective. 

Here is one video I used when I started from Keith Appleton (who has lots of good videos related to model steam engines):



In addition to the sites referenced in prior posts, you may also get the necessary fittings for connecting the gas line from Forest Classics or from Stuart Models.  Links below.

http://www.forest-classics.co.uk/

One other note, never put any water in the boilers other than distilled water, never leave water in the boilers and always oil all moving parts with a good steam oil before and after each steam up (which you can also buy form Stuart Models, Forest Classics or Ministeam). 

Welcome from the great State of Texas and good luck!  And please post a video when you get the traction engine going.

Non-active member Dean Williams also has some good advice in the reference library

My thanks to you and Nick for your advice.  I see that the silver soldering utilizes fittings so it is not much different than doing copper plumbing in a house that I'm use to.  I hadn't understood that there were fittings in these smaller sizes and was having trouble imagining that the tubes could be soldered together cut face to cut face.  Mission Impossible.  Looking at the tractor, I see metal tubing joined together at points with some kind of flexible tubing, probably silicon.  These are the tubes that have degraded and need to replaced.  I'll look into starting fresh with continuous runs of cooper tubing.  If there is a source for some kind of flex tubing that I can use in the meantime, just to get the thing fired up, please let me know.
