so I hadn't built the penny stove correctly after all... duh... I left out the 6 jets on the edge. once I found the pushpin again and put those where they belonged, it worked much better. I could fill the stove more because the alcohol flowed into the chamber better, and the jets meant the fuel could burn easily without the penny buzzing around in the middle. it's quieter, hotter, and burns longer. and I found a short pipe nipple, maybe 1-1/4" or so, that works perfectly to raise it to within about an inch of the pot it's heating. I'm in business! I may not be buying those butane canisters ever again, but even if I do, I'll be using them a lot less.
