Trangia question

[tyggriffic]

So, I just managed to score a second-hand Trangia cookware system on gumtree for $10. Upon closer inspection, I notice that the actual burner part internal section where the fuel goes seems to have holes and isn't watertight. I filled it with water to a marked level to check and water definitely leaks from the inner chamber to the outer and if I empty the water out there is still a portion that remains inside that exits via the holes. I've tried searching everywhere, but can't find out if this is a serious defect and I shouldn't use it or if it's completely ok if not normal. Any advice appreciated.

All good from my understanding of your process. The burners have two chambers with a wall in-between, the holes go into the second/exterior chamber and magic happens and it pressurises or something like that and makes a sweet flame. Try it with some metho, you wont blow yourself up. Just give it a couple of minutes of burn time to let it pressurise and make jet like flames. Should be a video out there somewhere detailing a Trangia burner. Good luck.

Completely normal. Fuel has to move from inner to be outer in order to be burned and exit via the jets. There is also a wick lining the outer compartment.

You scored a bargain!

This is what a Trangia burning looks like, the flames will get bigger as it heats up.

Just one thing....check that there is an O ring seal on the lid of the burner as it will leak without one if you leave some Metho in it.
Don't fill it full up just up to roughly the flangey bit that it sits on in the windshield.
You have done very well for $10.00....absolute bargain.

Indeed a bargain. Before going on a walk with the stove, it will probably pay you to cook with the stove in the back yard or open air. Trangias are foolproof but fiddly to adjust. Trangias can flare, which makes them a bit dodgy for cooking inside some tents.

It's normal to keep the meths in the burner head when stored in the pack. The lid has an O ring to seal the holes. It's quite important to make sure that the head is nearly cold before putting the lid on. If the head is too hot the O ring will melt against the holes in the head. When the lid is taken off the O ring will stay on the head. This happened to a mate and he did not see the O ring until it caught fire, big stink. Putting the lid on when the head is still warm ensures a slight vacuum, making a spill unlikely.

You may wish to carry a spare O ring wrapped in a small plastic bag to preserve the integrity. Allow about 100 ml of meths a day.

Thanks guys. I was pretty impressed with the score myself, especially when I checked retail, and even resell prices. Have given it a good clean today, making sure to scrub around the vents. Am just drying it out and will give it a test tomorrow. It has the o-ring. It was rather well stuck to the lid, so I gave it a wash too and used some waterproof o-ring lube I had in the toolbox. The whole thing seems to be complete, burner, stove parts, kettle, both saucepans, frying pan and grips. And didn't need much cleaning at all. Looking forward to making cooking a little more enjoyable and easy. Will add a little bit more weight but I'm sure if I just take the parts I need for now it will be fine. Thanks for the advice.

If you want to cut down on the rather large volume of a Trangia, try this. Get a 425 g tin of anything. Remove the top, empty, clean. Cut a hole in the side for the burner head lid to go though and a dozen large holes near the lip. The billy sits on the top of the tin, or if the billy is smaller than the tin, on a piece of wire. This is much more compact than a Trangia, but its probably less efficient. If the billy is smaller than the tin, the tin can live in the billy when walking.

Yeah after packing it today for tomorrow's trip, we'll definitely be looking at some of these trangia hacks to cut down the bulkiness. I always go with my parter, so we share the weight, but as we both use really light backs, the smaller the better.
