When you’re looking to roast your own coffee, a popcorn popper or heat gun can be called up for the job. Then again, as one intrepid DIY-er shows us, a drill, a soup can and ingenuity can sub in just fine.
Tim Eggers’ soup can roaster set up is cheaper than pretty much any DIY roasting setup we’ve posted before, and doesn’t require much more than a willingness to punch a hole through a can. As he explains:
Roasting is simple. As you can see I simply stand the drill on my stove with the drum over the burner. The burner has no problem (even on low) heating the drum. I run the drill by using a pipe clamp over the trigger. I have added another large can (with the top and bottom removed) on the burner to condense the heat going up to the drum (photo below) …
I spent less than 10 bucks and thirty minutes building the drum. The drill and Dremel tool I already had. This is a simple to build and very sturdy drum.
Cheap, fairly simple, and it gets the beans roasted. Depending on what type of people your coffee snob friends are, it might just win you some major cred, too. If you’ve got a similarly bare-minimum roasting setup, do tell in the comments.
