This seemed as if it's the most likely forum for this. Not exactly smoking maple sap but you are cooking it.......sort of. My brother and I (mostly my bro) have a very small sugaring operation every spring. Attached a pic or two of the arch that he jerry rigged. That coffee can balanced by the chimney holds about a gallon of sap. There is a nail hole neat the bottom that "meters" a stream of sap as it boils away. Work isn't work when you're havin' fun.
