I've got the top to a Fosters can (a bad joke Australia plays on the rest of the world) cut and drilled like Tinny's Sketti stove but I was thinking a Heinie can bottom. Gotta work out the inner wall as the upper half of a Fosters is a bigger diameter that the bottom of either jumbo can.
I did build a jumbo open top side burner like yours. It burns really hot and it can hold 4+ ounces of fuel but it is fussy and tough to light. It can cook spaghetti but if you are burning 4 ounces of Heet for one meal you should probably use another type of stove. Still fun to tinker with them...
After choking down 3 canned Heinekens I'm thinking your original offer was a very generous one.
Thanks to all!
