Soup can coffee roaster


How awesome is this drill powered drum roaster? Very awesome.


I never tire of seeing new takes on building your own sample roaster. Keeping the beans moving is the key to an even roast. Tim Eggers decided to use a drill to turn his drum, made from a soup can. He cut and folded vanes into the drum to aid the tumbling. A second soup can drum focuses the heat from his stove-top burner. Genius idea, and look at those lovely beans.
