Picture of Do It Yourself Hand Cranked Coffee Roaster.

As a Colombian I love coffee, but roasting it has always been a pain in the neck. The other day while I was watching videos I saw an antique roaster being used and I knew I had to make one like that to make roasting easier. I went to the room where I keep my scrap and found everything I needed to make it right at home, so here it is guys. Enjoy it!

Step 1: Materials.

Picture of Materials.
The materials I used are as follows:

- A 3/8" construction rod which was getting rusted in my backyard (2 meter long). 
- A piece of aluminum pipe where the rod will fit loose (for the crank). To be honest, I'm not too good at aluminum sizes, so just look        
    at the pictures please.
- Two tuna cans. 
- A scrap stainless steel sheet that was left from another project (30 Cm X 20 Cm).
- A couple of washers. 
- A short piece of thick wire about 1/8".

You are a genius. I have always wanted to try roasting some coffee beans Thank you for posting this

Be careful. Many cans have a plastic like film on the inside, be sure to burn it off or find a way to remove it. This film can release toxins into your food when heated. With that safety note aside this is a fantastic idea.

You're right. That's one of the reasons I chose to use stainless steel, but I actually forgot to mention that you have to "break-in" the roaster without any beans for at least 20 minutes. Thanks for reminding me. I'm going to update the instructable.

This device can be used to roast also sunflower seeds, thanks for sharing it.
