an interesting stove Mags - is it similiar to a kelly kettle thingie ?
The cooker was originally intended for use with Meta fuel tablets...the Swiss equivalent of Hexi and Esbit tablets.I've tried about every alky stove version I can think of in it,,,problem is that anything pressurized will get overheated and flare up or burn inefficiently from the thermal feedback. After much experimentation, I've settled on using gelled fuel in mine. Using a steel tuna can with a single row of holes...basically a Supercat used in chimney mode. I get an inward jet effect which keeps the flames away from the walls of the stand. The tuna can gets stowed upside-down on top of the cork.I have seen photos of meltdowns caused by burning wood in these cookers. I think the users used pieces of splitwood and allowed the coals to build up. I would not use wood in mine, but I think bunches of small, fast burning twigs not larger than pencil size would be OK.The bottle is the same diameter as a 1L Sigg. I'm not able to lock the cup closed because it looks like the shoulder of the SIgg is higher and interfere with the cup. Mine are contemporary bottles...I wonder if an older Sigg has a lower shoulder?
