You need a ratio of around 1:5 to 1 I tend to go upto 1:8 to 1 and they run well
When I get a little more time if you are going to build a Stirling Jan Ridders has a very good write up on his site for the basics of designing these little engines
This is my take on a very old Doll design circa 1890-1910

And this one despite what people say Stirlings can produce enough power to drag themselves along

Be careful they become addictive
I find stainless steel with a simple heat dam or better still glass hot end caps work well.The glass ones are just cut down test tubes although for clumsy hands like mine they are a bit fragile
for the stainless kitchen tools are handy as is electrical conduit and car exhaust pipes .Lifes simple to short to machine them from sold and a copper end cap hard soldered on works well
cheers
frazer

This is the link to some design info for building these engines
Iv used it to build several of my own designed engines with no problems and more importantly no failures

Hi Tony,

A couple of verticals to ponder over.

You have two of these cast iron stoves maybe a twin cylinder

Also found this one which would be a good conversion for you.

Julius has a couple of fan designs that may well fit, also look at Brians "head cold" thread for another sterling based on a fan design.

You will need a way to let the gasses out either holes or a chimney.

If you do go the steam/boiler route then you could substitute your casting for the Mapp gas cylinder used on this rather nice engine.

Hi Frazer,

Many thanks for the links and information, alas the internet here in Madeira is very slow so I really won't be able to appreciate them until we are back in the UK. Also I have no means of printing so looking at plans etc on my lap top is a bit of a pain.

Hi Jason,

Thank you also for the information. A very interesting use of empty propane bottles.

We should be back in the UK in twelve days or so and I am looking forward to having a good look at the ideas that members have suggest for a use of the stove.

Regards Tony.

Madeira? . . . As in Madeira Portugal!
Tony I have a new suggestion. . . . . Stay in Madeira as long as you can.
We just went through a week of Cold Weather Advisories (-30 to -37 wind chills) from Environment Canada. Sad to think that this morning when I saw that the wind chill was only -22C I thought “good it’s finally warming up”. I remember earlier you mentioned that it was 17C and come to think of it that’s as warm as it gets at work. They’ve gone Green and turned down the boilers.
Enjoy the rest of your vacation

Hi Bob,

Yes Madeira about 300 miles off North Africa. You might be right looking at the weather at home with low temperatures and snow! Though there is snow in Madeira at the moment on it 6000 foot mountains, today it is a pleasant 19 C though as our apartment is 1800 feet above the sea it is a few degrees lower. When I say over the sea I mean just that we are about 200/300 feet horizontally from the sea but it is a long way down. On weekends para gliders wave as they pass our balcony!

We have another 10 days or so before we return to Old South Wales and we are not looking forward to the temperature drop. Still it will be good to get back to the shed after it has warmed up and play with the stove along with other projects.

Regards Tony.
