Next step: roasting coffee. A few unanswered questions at the moment, which I will ponder:
1. Is the heat/RF shielding from an Xbox 360 food safe... Appears to be just plain old aluminum, no coatings. Probably fine.
2. Same question on the bits of slight gold-tint TV antenna I used for the tilt wheel. Those TV antennas are a soft aluminum, as well, unclear to me what the gold/bronze tint on those is.
(both obviously can be replaced now that this works, mechanically -- can definitely replace the disk with a random piece of $1 or $2 pizza pan from the dollar store instead of an Xbox 360... and can find some non-colored metal for the angled part inside).

Looks like TV antennas are typically extruded 6061 aluminum. Aluminum is used as a cookware (used to be more common) and we do drink out of aluminum cans.... But apparently they don't suggest aluminum anymore due to some toxicity issues. Looks like I will go snag a cheap steel pizza pan from the dollar store and cut a new wheel, just because.

Okay, opted for the food grade thin steel and will also roll my own spacers from the material, just to be safe. Bicycled down to the dollar store. The frame bag I sewed looks to be the right size for snacks, maybe a lunch. Right side zipper was fortuitous as it makes it easier to snack while riding..

Pizza pan parts made. Built my own round stock from pizza pan parts. #diy #coffeeroaster

First bean test... failure! The angled metal failed to resist the weight of beans. I pulled them from the shaft and pushed the collars and bent the disk. #diy #coffeeroaster

Once that was fixed, determined it was having issues if coffee was over the shaft in depth. Not a lot of capacity. Half of a Talenti container. #diy #coffeeroaster

I think this is the right video... #coffee

239F with heat gun set to "high". Ambient temp is 56F. #coffee

Roasting! This is right st "first crack"
-
FLIR says 465F after first crack #flir

Final roasted product! It went a little farther than I wanted, but the headlamp I was using ran out of batteries and I had no visual of the roast at the end. These are halfway between first and second crack, I believe. I was aiming for slightly lighter. This is REALLY consistent roasting compared with my usual. #coffee #roasting
