I am mechanically inept. To roast green coffee beans use a WestBend Hot Air Corn Popper or Popper II, 1200 watts, 120 volts. These have side air vents. Avoid air poppers with the air vent on the bottom as this will burn the green beans.
Put in 3/4 C green beans plug in and in 10 minutes or so your beans will be roasted. You can increase the time to suit your taste. Watch the color while they are being roasted to decide how dark and shiny you want your beans.. Cool roasted beans are ready to grind. Mix and match roasted beans and times to suit your taste. Here green beans are $4/lb.
Beware. These machines are becoming harder and harder to find used as people are figuring out this method.

Hi,
I am interested in building this project, but I'm wondering if there are better templates available? The article shows a photo of somone (the author presumably) using a template placed directly on the aluminum stock to cut the triangle piece. And the article says that those templates are available here. However, since the blueprints provided here are .gif files they do not print in their actual dimensions. Are there perhaps pdf files available? Or perhaps I'm missing something, is there an easy way to do this, or is everyone just drawing the shaps onto the material?
thanks!Posted by electricz on December 02, 2006 at 08:46:11 Pacific Time

Hey, sorry for that post, I just measured my print-outs of the .gif's again and they are pretty accurates. I mis-measured the first time. Woops!Posted by electricz on December 02, 2006 at 08:53:05 Pacific Time

I really want to make this coffee roaster, but I'm not sure I have the time or energy to craft the basket. If someone else makes the jig and crafts the basket, I'd pay 20 bucks for a finished basket. Anyone interested?Posted by btravis on November 10, 2006 at 17:11:26 Pacific Time

I'm planning to make one and if I make one I can make two. It may cost more than $20 though, depending on the cost of materials.Posted by millwright on November 11, 2006 at 20:04:45 Pacific Time

Let me know your price!
I bought a stainless steel strainer from Bed Bath & Beyond, but I don't know if it'll do the trick. It's kinda shallow.Posted by btravis on November 12, 2006 at 07:26:22 Pacific Time

.025 stainless steel mesh is the only material I found that would resist the heat. Lesser thickness and quality mesh results in burn-through which then leaks (oil-containing) beans into the propane burner--not safe. Please stick with .025 stainless.

Let us know how that works out.
Be aware there are different grades of stainless. I bought a neat little stainless tea kettle from Amazon that I had to send back because it stunk so bad when I heated it on the stove.Posted by millwright on November 12, 2006 at 18:33:46 Pacific Time
