The Pop-Pop Steamboat in MAKE Volume 28 calls for using small tea candles for the engine’s heat source, but I found that it didn’t work very well. So I decided to make this small alcohol-burning lamp instead, and it significantly improved its performance.
In this project I will go over how to turn down two brass end-caps on a small lathe and then solder them onto a short length of copper pipe to make an alcohol-burning lamp to fuel your Pop-Pop boat. This project is for those who have basic skills with a lathe and metalworking. I will not go over dimensions, so you can come up with your own design. Have fun!
