After nearly 5 years and several hundred pounds of roasted coffee, my Poppery roaster gave up. The motor will only run at about half speed. It appears the brushes are worn out. This thing has been a workhorse. The brushes could probably be replaced, but they are not designed as such and it would be a challenge.
I've learned alot along the way. I'll admit to being just a little sentimental when I took it apart and diagnosed the problem.
It is one of two that I alternate when roasting (one cools while the other roasts). I have a few backup units stashed in the garage, but they will need the mods to get up and running. I will probably do that since I've been looking at an Arduino based controller setup, and I think these will work well for small batches.
I've many times considered moving on to something bigger and with more control, but until now I've been satisfied. I did send a note to an acquaintance who has a Behmor sitting in his closet collecting dust. Hopefully a deal can be made there. I roast 2-3 lbs a week, so the volume is hot huge, but that is more than 2 hrs of my time. Something that would do 9 to 12 oz roasts would cut that time in half.
