Get a stove top pressure cooker and modify the pop off valve to receive tubing. Plastic will do.
Buy a length of coppper tubong, 1/4" id is fine. Roll it into a coil around a a mandrel roughly 3 1/2 inches in diameter. An old orange juice or coffee can will do.
Obtain a used #10 can from a cafeteria some where and drill a 1/4 inch hole in the side near the bottom. Place the copper coil (minus the mandrel) in the #10 can and feed the bottom end out the hole. Seal with JB weld epoxy or solder around the joint to stop leaks.
Connect the length of tube from the pressure cooker to the coil. Fill the #10 can with water. Voila.... a still.
Place the beer, the fermented product, in the cooker and bring to a boil. Regulate the heat to produce a simmer. The alcohol will boil off and condense in the coil dripping out into a receptacle. If steam comes out the bottom of the coil, reduce the heat. If the water in the #10 can gets hot, remove and replace with colder water.
For corn likker, ferment cornmeal and sugar with wine yeast.
