    I think a domestic oven rotisserie would be a little slow, coffee roasters are circa 30RPM
    Temperature should prob be pre-heated to about 220-240C, there would be a fair drop in temperature when you open the door and load the beans but it should recover pretty quick as it's a small volume.

    ...but give it a try and let us know how goes!

    Take lots of notes, eg: coffee weight before and after, times and you will be able to adjust future roasts from what you learn.

    I've since chosen to stick with my original path which is a BBQ roaster drum in a BBQ. My first drum I made from perforated aluminium, my welds are hideous but it does the trick for first go and cost nothing. It'll comfortably do up to 5kg but I mostly do 1kg in about 10-11min. I use a 4 burner bbq on natural gas. I've modified a windscreen wiper motor to run at about 35rpm, I've wasted only about 5kg to get the hang of it but the results are amazing! I'm now setting up several PID's and monitoring software so I can get better consistency and develop profiles. Killing my Behmor after upgrading it to plus and leaving it unattended then smoking out the whole yard was a good motivator!

    Interested to know how/where you're setting up the temp probes as inputs to the PID.

    I'm running a slip ring at the end of the shaft, then wires through the shaft and finally two probes, one at the bottom section inside the basket so It sits in the middle of the beans to monitor the bean temp; the second about an inch below the main shaft which monitors the air temp in the basket. I'll also be adding two more to monitor air temps both in and out
