This is something for the Caravel lovers. I will be using this when out camping and such. It is a Trangia style gas burner inside a Caravel. The burner does heat up the base a bit and it has no spark starter so to negate this I start the burner and put the empty or mostly empty boiler on. I add boiling water so I can make shots quicker. I can start cooling the boiling water with cold water if I make more shots and it starts to get too hot. If I am making just one shot I just add water from a rolling boil and make a shot on the fly. I kept the old electric setup as it is working and is more practical when using the machine at home. I would discourage you to do this gas conversion as the thermostat is finicky to put back together.

Wow cool, Are you modified this? Any step by step pictures for this modification ?

Hi,
you need a Trangia style gas burner and you unscrew it and remove the clamp from the burner. You then insert it in to your gutted Caravel.



I also used a screw from the ceramic insulation as shown. The burner base is a very tight fit. It does not move at all.


The electric thermostat on this machine is a work of art. It has a 10 degree dead spot and once removed it is hard to make it click again.

Wow ! Great modification ! Emidio Salati would have been proud of you.

Some Aluminum foil to protect/isolate the body could be a good addition.

That's very clever! Perhaps at some point you'll find a small piezoelectric igniter you can sneak into the case to make things easier.

Your comments got me thinking about somehow using a Peltier on the Caravel for phone charging while camping. Just thinking out loud, sorry. I also hope Mr. Salati approves and is not turning in his grave.

Nice idea Primus! My only thought: Does the burner get enough air to provide good fuel combustion after the water container is in place?

spressomon you have a good point. Trangia has more side air intake and more of a top gap than the Caravel. I will put some small spacers on the Caravel so the legs are a bit higher and also try withouth the bottom cover and see what that does. I do use a very low flame as opposed to when using the Trangia.
Thanks for your question.

Hi Primus,

This is a really cool er..... I mean very hot mod on the Caravel! Would be great to see it in action.

Cheers

hi Gabor, yes it is a hot mod. haha. I took some pictures. I will try and make a video eventually, but I have to find a helper.


the pictures show a change, the burner is further down so the flame has more oxygen, thank you spressomon for your advice.
