you will gain an eye for cans of all types if you keep playing around with these stoves, heh. I believe jim wood lists the various types of cans that are aluminum, but you can make it easy by looking for the gold colored fancy feast cat food cans, you can tell if it's aluminum by tapping on the can once you get a feel for it too. Steel tends to also have a rolled joint on the bottom, while aluminum tends to be pressed. Not always, but usually.
For a heatshield ace hardware sells 6" flashing, maybe also 5", for almost nothing per foot. You can also buy a oven roasting pan then carefully cut the edges off and fold it flat then cut the screen out that. the flashing is strong enough to hold it's form when packed / rolled up inside the pot vertically, the stove pan isn't, but is foldable.
I believe jim wood recommends about a 1/2" gap in the screen, ie, diameter of screen is 1" larger than pot diameter. Measure pot diameter from the bottom of the pot, not the top, because the top has a lip that sticks out and doesn't count.
These require a fair amount of air, so you want air holes along half the wind / heat screen, so you can always face it opposite the wind. wind totally wipes out stove performance, which you will discover, but a good reasonably tall wind screen, and situating the stove out of the wind, helps a lot.
It's useful to pick up some 1oz medicine measuring cups, some pharmacies have them, so you know what it actually takes to boil the amount of water you want to boil per meal, that way you can bring a bit more than what you need but not too much more.
A heat reflector cut out of a pie tin or the rest of the stove pan, inserted under the stove, helps avoid forest fires, and also reflects heat back up to the pot, that's real threat. it's only a matter of time in my opinion before alcohol stoves are banned increasingly in summers in more and more parks due to the poor practices and designs out there.
Your pot is perfect for all stoves made I believe, just the right width. Do keep in mind with the jim wood super cat, if you knock the pot over, you knock the stove over too, that's personally why I prefer stoves with stands, but the super cat is a fine stove to start out with, but the efficiency is not very good. Jim wood to his credit states that he's not an engineer or designer, and doesn't pretend to have developed the best stove out there, just one that cooks pretty fast. Super cat is good for speed by the way, the ion is slower, which is one reason it's more efficient, that and a more efficient general design.
