Stay Warm with the Heiny Heater!

Don't cut out the entire bottom of the soup can. Instead, cut a hole in center of the soup can's bottom leaving about 3/8 inch (1 cm) band of metal around the perimeter. I used tin snips. Slide the soup can over keg top tabs then bend the tabs back over soup can bottom perimeter band. I used a piece of dowel to bend the tabs back. You could use a hammer handle. For a more secure mount, drill through the tabs and soup can and install 2-3 sheet metal screws connecting together the tabs, can and keg.
