There's quite a few things in 4"dia. x 2:5"high tins, pineapple rings etc.but the best (thickest) seems to be Heinz sponge puddings. So remove one end and use a church key opener to punch x10 triangular holes right through the wall at the open end.These can be wiggled backwards and forwards untill they snap off.Then at the closed end only jus pierce through with the opener to make small triangular holes these although harder to do can also be snapped off long nose pliers help.Then a quick burn off the paint in a fire and a sand for cosmetics.The air intakes being above the bottom allow for priming meths without spilling burning fuel. This being only 2nd post I'll try and put two photos here, shown with a 12cm Zebra billy, for the 1000 word picture the small tin is an 80 gm. Tuna tin to use as a snuffer.
