This is my offering- hubby and I made it a couple of years ago to heat my tipi. We left the valve open, upside down, for a week, then removed it (not standing over it, just in case, I didn't fancy a permenantly fixed bindi protruding from my forehead
) and filled with water twice, right up to the top as propane is heavier than air and I hadn't got him insured yet. We left it full for a few days each time then marked out, drilled the corners to start the cuts off, welded strip inside and a couple of lugs for a grating, some hinges and cheap door handles in and the jobs a good 'un!
he chimney attaches with a little collar- its essential to get a good draw when its cold and made the tipi a lot less smoky. You can balance a crusader nicely on the rim or for warm wash water, in the handle against the chimney.
I use the ash pan as a griddle... you get nice crunchy bits unless you cover over with some silicon fabric though! A good wire brushing after the first fire gave a real nice effect removing the heated paint layers... this is from last weekend so its developed more of a rust patina nowdays!
If I did another, I'd add a bead for fire rope round the doors and insert a butterfly valve into the chimney so it could be banked and kept in overnight. It isn't lightweight camping though!
